Excelize

Introduction

Excelize is a library written in pure Go providing a set of functions that allow you to write to and read from XLSX files. Supports reading and writing XLSX file generated by Microsoft Excel™ 2007 and later. Supports saving a file without losing original charts of XLSX. This library needs Go version 1.10 or later. The full API docs can be seen using go's built-in documentation tool, or online at go.dev and docs reference.

Basic Usage

Installation
go get github.com/hjki456789/excelize
Create XLSX file

Here is a minimal example usage that will create XLSX file.

package main

import (
    "fmt"

    "github.com/hjki456789/excelize"
)

func main() {
    f := excelize.NewFile()
    // Create a new sheet.
    index := f.NewSheet("Sheet2")
    // Set value of a cell.
    f.SetCellValue("Sheet2", "A2", "Hello world.")
    f.SetCellValue("Sheet1", "B2", 100)
    // Set active sheet of the workbook.
    f.SetActiveSheet(index)
    // Save xlsx file by the given path.
    if err := f.SaveAs("Book1.xlsx"); err != nil {
        fmt.Println(err)
    }
}
Reading XLSX file

The following constitutes the bare to read a XLSX document.

package main

import (
    "fmt"

    "github.com/hjki456789/excelize"
)

func main() {
    f, err := excelize.OpenFile("Book1.xlsx")
    if err != nil {
        fmt.Println(err)
        return
    }
    // Get value from cell by given worksheet name and axis.
    cell, err := f.GetCellValue("Sheet1", "B2")
    if err != nil {
        fmt.Println(err)
        return
    }
    fmt.Println(cell)
    // Get all the rows in the Sheet1.
    rows, err := f.GetRows("Sheet1")
    for _, row := range rows {
        for _, colCell := range row {
            fmt.Print(colCell, "\t")
        }
        fmt.Println()
    }
}
Add chart to XLSX file

With Excelize chart generation and management is as easy as a few lines of code. You can build charts based off data in your worksheet or generate charts without any data in your worksheet at all.

Excelize

package main

import (
    "fmt"

    "github.com/hjki456789/excelize"
)

func main() {
    categories := map[string]string{"A2": "Small", "A3": "Normal", "A4": "Large", "B1": "Apple", "C1": "Orange", "D1": "Pear"}
    values := map[string]int{"B2": 2, "C2": 3, "D2": 3, "B3": 5, "C3": 2, "D3": 4, "B4": 6, "C4": 7, "D4": 8}
    f := excelize.NewFile()
    for k, v := range categories {
        f.SetCellValue("Sheet1", k, v)
    }
    for k, v := range values {
        f.SetCellValue("Sheet1", k, v)
    }
    if err := f.AddChart("Sheet1", "E1", `{"type":"col3DClustered","series":[{"name":"Sheet1!$A$2","categories":"Sheet1!$B$1:$D$1","values":"Sheet1!$B$2:$D$2"},{"name":"Sheet1!$A$3","categories":"Sheet1!$B$1:$D$1","values":"Sheet1!$B$3:$D$3"},{"name":"Sheet1!$A$4","categories":"Sheet1!$B$1:$D$1","values":"Sheet1!$B$4:$D$4"}],"title":{"name":"Fruit 3D Clustered Column Chart"}}`); err != nil {
        fmt.Println(err)
        return
    }
    // Save xlsx file by the given path.
    if err := f.SaveAs("Book1.xlsx"); err != nil {
        fmt.Println(err)
    }
}
Add picture to XLSX file
package main

import (
    "fmt"
    _ "image/gif"
    _ "image/jpeg"
    _ "image/png"

    "github.com/hjki456789/excelize"
)

func main() {
    f, err := excelize.OpenFile("Book1.xlsx")
    if err != nil {
        fmt.Println(err)
        return
    }
    // Insert a picture.
    if err := f.AddPicture("Sheet1", "A2", "image.png", ""); err != nil {
        fmt.Println(err)
    }
    // Insert a picture to worksheet with scaling.
    if err := f.AddPicture("Sheet1", "D2", "image.jpg", `{"x_scale": 0.5, "y_scale": 0.5}`); err != nil {
        fmt.Println(err)
    }
    // Insert a picture offset in the cell with printing support.
    if err := f.AddPicture("Sheet1", "H2", "image.gif", `{"x_offset": 15, "y_offset": 10, "print_obj": true, "lock_aspect_ratio": false, "locked": false}`); err != nil {
        fmt.Println(err)
    }
    // Save the xlsx file with the origin path.
    if err = f.Save(); err != nil {
        fmt.Println(err)
    }
}

func (*File) AddSparkline 

func (f *File) AddSparkline(sheet string, opt *SparklineOption) (err error)

AddSparkline provides a function to add sparklines to the worksheet by given formatting options. Sparklines are small charts that fit in a single cell and are used to show trends in data. Sparklines are a feature of Excel 2010 and later only. You can write them to an XLSX file that can be read by Excel 2007 but they won't be displayed. For example, add a grouped sparkline. Changes are applied to all three: 

err := f.AddSparkline("Sheet1", &excelize.SparklineOption{
    Location: []string{"A1", "A2", "A3"},
    Range:    []string{"Sheet2!A1:J1", "Sheet2!A2:J2", "Sheet2!A3:J3"},
    Markers:  true,
})

The following shows the formatting options of sparkline supported by excelize: 

 Parameter | Description
-----------+--------------------------------------------
 Location  | Required, must have the same number with 'Range' parameter
 Range     | Required, must have the same number with 'Location' parameter
 Type      | Enumeration value: line, column, win_loss
 Style     | Value range: 0 - 35
 Hight     | Toggle sparkline high points
 Low       | Toggle sparkline low points
 First     | Toggle sparkline first points
 Last      | Toggle sparkline last points
 Negative  | Toggle sparkline negative points
 Markers   | Toggle sparkline markers
 ColorAxis | An RGB Color is specified as RRGGBB
 Axis      | Show sparkline axis

func (*File) AddTable 

func (f *File) AddTable(sheet, hcell, vcell, format string) error

AddTable provides the method to add table in a worksheet by given worksheet name, coordinate area and format set. For example, create a table of A1:D5 on Sheet1: 

err := f.AddTable("Sheet1", "A1", "D5", ``)

Create a table of F2:H6 on Sheet2 with format set: 

err := f.AddTable("Sheet2", "F2", "H6", `{"table_name":"table","table_style":"TableStyleMedium2", "show_first_column":true,"show_last_column":true,"show_row_stripes":false,"show_column_stripes":true}`)

Note that the table must be at least two lines including the header. The header cells must contain strings and must be unique, and must set the header row data of the table before calling the AddTable function. Multiple tables coordinate areas that can't have an intersection.

table_name: The name of the table, in the same worksheet name of the table should be unique

table_style: The built-in table style names 

TableStyleLight1 - TableStyleLight21
TableStyleMedium1 - TableStyleMedium28
TableStyleDark1 - TableStyleDark11

func (*File) AddVBAProject 

func (f *File) AddVBAProject(bin string) error

if err := f.SetSheetPrOptions("Sheet1", excelize.CodeName("Sheet1")); err != nil {
    fmt.Println(err)
}
if err := f.AddVBAProject("vbaProject.bin"); err != nil {
    fmt.Println(err)
}
if err := f.SaveAs("macros.xlsm"); err != nil {
    fmt.Println(err)
}

func (*File) AutoFilter 

func (f *File) AutoFilter(sheet, hcell, vcell, format string) error

AutoFilter provides the method to add auto filter in a worksheet by given worksheet name, coordinate area and settings. An autofilter in Excel is a way of filtering a 2D range of data based on some simple criteria. For example applying an autofilter to a cell range A1:D4 in the Sheet1: 

err := f.AutoFilter("Sheet1", "A1", "D4", "")

Filter data in an autofilter: 

err := f.AutoFilter("Sheet1", "A1", "D4", `{"column":"B","expression":"x != blanks"}`)

column defines the filter columns in a autofilter range based on simple criteria

It isn't sufficient to just specify the filter condition. You must also hide any rows that don't match the filter condition. Rows are hidden using the SetRowVisible() method. Excelize can't filter rows automatically since this isn't part of the file format.

Setting a filter criteria for a column:

expression defines the conditions, the following operators are available for setting the filter criteria: 

==
!=
>
<
>=
<=
and
or

An expression can comprise a single statement or two statements separated by the 'and' and 'or' operators. For example: 

x <  2000
x >  2000
x == 2000
x >  2000 and x <  5000
x == 2000 or  x == 5000

Filtering of blank or non-blank data can be achieved by using a value of Blanks or NonBlanks in the expression: 

x == Blanks
x == NonBlanks

Excel also allows some simple string matching operations: 

x == b*      // begins with b
x != b*      // doesnt begin with b
x == *b      // ends with b
x != *b      // doesnt end with b
x == *b*     // contains b
x != *b*     // doesn't contains b

You can also use '*' to match any character or number and '?' to match any single character or number. No other regular expression quantifier is supported by Excel's filters. Excel's regular expression characters can be escaped using '~'.

The placeholder variable x in the above examples can be replaced by any simple string. The actual placeholder name is ignored internally so the following are all equivalent: 

x     < 2000
col   < 2000
Price < 2000

func (*File) InsertPageBreak 

func (f *File) InsertPageBreak(sheet, cell string) (err error)

InsertPageBreak create a page break to determine where the printed page ends and where begins the next one by given worksheet name and axis, so the content before the page break will be printed on one page and after the page break on another.

func (*File) InsertRow 

func (f *File) InsertRow(sheet string, row int) error

InsertRow provides a function to insert a new row after given Excel row number starting from 1. For example, create a new row before row 3 in Sheet1: 

err := f.InsertRow("Sheet1", 3)

Use this method with caution, which will affect changes in references such as formulas, charts, and so on. If there is any referenced value of the worksheet, it will cause a file error when you open it. The excelize only partially updates these references currently.

func (*File) MergeCell 

func (f *File) MergeCell(sheet, hcell, vcell string) error

MergeCell provides a function to merge cells by given coordinate area and sheet name. For example create a merged cell of D3:E9 on Sheet1: 

err := f.MergeCell("Sheet1", "D3", "E9")

If you create a merged cell that overlaps with another existing merged cell, those merged cells that already exist will be removed. 

             B1(x1,y1)      D1(x2,y1)
           +------------------------+

NewStreamWriter return stream writer struct by given worksheet name for generate new worksheet with large amounts of data. Note that after set rows, you must call the 'Flush' method to end the streaming writing process and ensure that the order of line numbers is ascending. For example, set data for worksheet of size 102400 rows x 50 columns with numbers and style: 

file := excelize.NewFile()
streamWriter, err := file.NewStreamWriter("Sheet1")
if err != nil {
    fmt.Println(err)
}
styleID, err := file.NewStyle(`{"font":{"color":"#777777"}}`)
if err != nil {
    fmt.Println(err)
}
if err := streamWriter.SetRow("A1", []interface{}{excelize.Cell{StyleID: styleID, Value: "Data"}}); err != nil {
    fmt.Println(err)
}
for rowID := 2; rowID <= 102400; rowID++ {
    row := make([]interface{}, 50)
    for colID := 0; colID < 50; colID++ {
        row[colID] = rand.Intn(640000)
    }
    cell, _ := excelize.CoordinatesToCellName(1, rowID)
    if err := streamWriter.SetRow(cell, row); err != nil {
        fmt.Println(err)
    }
}
if err := streamWriter.Flush(); err != nil {

Rows return a rows iterator. For example: 

rows, err := f.Rows("Sheet1")
if err != nil {
    fmt.Println(err)
    return
}
for rows.Next() {
    row, err := rows.Columns()
    if err != nil {
        fmt.Println(err)
    }
    for _, colCell := range row {

SetConditionalFormat provides a function to create conditional formatting rule for cell value. Conditional formatting is a feature of Excel which allows you to apply a format to a cell or a range of cells based on certain criteria.

The type option is a required parameter and it has no default value. Allowable type values and their associated parameters are: 

 Type          | Parameters
---------------+------------------------------------
 cell          | criteria
               | value
               | minimum
               | maximum
 date          | criteria
               | value
               | minimum
               | maximum

 unique        | (none)
 top           | criteria
               | value
 bottom        | criteria
               | value
 blanks        | (none)
 no_blanks     | (none)
 errors        | (none)
 no_errors     | (none)
 2_color_scale | min_type
               | max_type
               | min_value
               | max_value
               | min_color
               | max_color
 3_color_scale | min_type
               | mid_type
               | max_type
               | min_value
               | mid_value
               | max_value
               | min_color
               | mid_color
               | max_color
 data_bar      | min_type
               | max_type
               | min_value
               | max_value
               | bar_color
 formula       | criteria

The criteria parameter is used to set the criteria by which the cell data will be evaluated. It has no default value. The most common criteria as applied to {"type"："cell"} are: 

between                  |
not between              |
equal to                 | ==
not equal to             | !=
greater than             | >
less than                | <
greater than or equal to | >=
less than or equal to    | <=

You can either use Excel's textual description strings, in the first column above, or the more common symbolic alternatives.

Additional criteria which are specific to other conditional format types are shown in the relevant sections below.

value: The value is generally used along with the criteria parameter to set the rule by which the cell data will be evaluated: 

f.SetConditionalFormat("Sheet1", "D1:D10", fmt.Sprintf(`[{"type":"cell","criteria":">","format":%d,"value":"6"}]`, format))

The value property can also be an cell reference: 

f.SetConditionalFormat("Sheet1", "D1:D10", fmt.Sprintf(`[{"type":"cell","criteria":">","format":%d,"value":"$C$1"}]`, format))

type: format - The format parameter is used to specify the format that will be applied to the cell when the conditional formatting criterion is met. The format is created using the NewConditionalStyle() method in the same way as cell formats: 

format, err = f.NewConditionalStyle(`{"font":{"color":"#9A0511"},"fill":{"type":"pattern","color":["#FEC7CE"],"pattern":1}}`)
if err != nil {
    fmt.Println(err)
}
f.SetConditionalFormat("Sheet1", "A1:A10", fmt.Sprintf(`[{"type":"cell","criteria":">","format":%d,"value":"6"}]`, format))

Note: In Excel, a conditional format is superimposed over the existing cell format and not all cell format properties can be modified. Properties that cannot be modified in a conditional format are font name, font size, superscript and subscript, diagonal borders, all alignment properties and all protection properties.

Excel specifies some default formats to be used with conditional formatting. These can be replicated using the following excelize formats: 

// Rose format for bad conditional.
format1, err = f.NewConditionalStyle(`{"font":{"color":"#9A0511"},"fill":{"type":"pattern","color":["#FEC7CE"],"pattern":1}}`)

// Light yellow format for neutral conditional.
format2, err = f.NewConditionalStyle(`{"font":{"color":"#9B5713"},"fill":{"type":"pattern","color":["#FEEAA0"],"pattern":1}}`)

// Light green format for good conditional.
format3, err = f.NewConditionalStyle(`{"font":{"color":"#09600B"},"fill":{"type":"pattern","color":["#C7EECF"],"pattern":1}}`)

type: minimum - The minimum parameter is used to set the lower limiting value when the criteria is either "between" or "not between". 

// Hightlight cells rules: between...
f.SetConditionalFormat("Sheet1", "A1:A10", fmt.Sprintf(`[{"type":"cell","criteria":"between","format":%d,"minimum":"6","maximum":"8"}]`, format))

type: maximum - The maximum parameter is used to set the upper limiting value when the criteria is either "between" or "not between". See the previous example.

type: average - The average type is used to specify Excel's "Average" style conditional format: 

// Top/Bottom rules: Above Average...
f.SetConditionalFormat("Sheet1", "A1:A10", fmt.Sprintf(`[{"type":"average","criteria":"=","format":%d, "above_average": true}]`, format1))

// Top/Bottom rules: Below Average...
f.SetConditionalFormat("Sheet1", "B1:B10", fmt.Sprintf(`[{"type":"average","criteria":"=","format":%d, "above_average": false}]`, format2))

type: duplicate - The duplicate type is used to highlight duplicate cells in a range: 

// Hightlight cells rules: Duplicate Values...
f.SetConditionalFormat("Sheet1", "A1:A10", fmt.Sprintf(`[{"type":"duplicate","criteria":"=","format":%d}]`, format))

type: unique - The unique type is used to highlight unique cells in a range: 

// Hightlight cells rules: Not Equal To...
f.SetConditionalFormat("Sheet1", "A1:A10", fmt.Sprintf(`[{"type":"unique","criteria":"=","format":%d}]`, format))

type: top - The top type is used to specify the top n values by number or percentage in a range: 

// Top/Bottom rules: Top 10.
f.SetConditionalFormat("Sheet1", "H1:H10", fmt.Sprintf(`[{"type":"top","criteria":"=","format":%d,"value":"6"}]`, format))

The criteria can be used to indicate that a percentage condition is required: 

f.SetConditionalFormat("Sheet1", "A1:A10", fmt.Sprintf(`[{"type":"top","criteria":"=","format":%d,"value":"6","percent":true}]`, format))

type: 2_color_scale - The 2_color_scale type is used to specify Excel's "2 Color Scale" style conditional format: 

// Color scales: 2 color.
f.SetConditionalFormat("Sheet1", "A1:A10", `[{"type":"2_color_scale","criteria":"=","min_type":"min","max_type":"max","min_color":"#F8696B","max_color":"#63BE7B"}]`)

This conditional type can be modified with min_type, max_type, min_value, max_value, min_color and max_color, see below.

type: 3_color_scale - The 3_color_scale type is used to specify Excel's "3 Color Scale" style conditional format: 

// Color scales: 3 color.
f.SetConditionalFormat("Sheet1", "A1:A10", `[{"type":"3_color_scale","criteria":"=","min_type":"min","mid_type":"percentile","max_type":"max","min_color":"#F8696B","mid_color":"#FFEB84","max_color":"#63BE7B"}]`)

This conditional type can be modified with min_type, mid_type, max_type, min_value, mid_value, max_value, min_color, mid_color and max_color, see below.

type: data_bar - The data_bar type is used to specify Excel's "Data Bar" style conditional format.

min_type - The min_type and max_type properties are available when the conditional formatting type is 2_color_scale, 3_color_scale or data_bar. The mid_type is available for 3_color_scale. The properties are used as follows: 

// Data Bars: Gradient Fill.
f.SetConditionalFormat("Sheet1", "K1:K10", `[{"type":"data_bar", "criteria":"=", "min_type":"min","max_type":"max","bar_color":"#638EC6"}]`)

The available min/mid/max types are: 

min        (for min_type only)
num
percent
percentile
formula
max        (for max_type only)

mid_type - Used for 3_color_scale. Same as min_type, see above.

max_type - Same as min_type, see above.

min_value - The min_value and max_value properties are available when the conditional formatting type is 2_color_scale, 3_color_scale or data_bar. The mid_value is available for 3_color_scale.

mid_value - Used for 3_color_scale. Same as min_value, see above.

max_value - Same as min_value, see above.

min_color - The min_color and max_color properties are available when the conditional formatting type is 2_color_scale, 3_color_scale or data_bar. The mid_color is available for 3_color_scale. The properties are used as follows: 

// Color scales: 3 color.
f.SetConditionalFormat("Sheet1", "B1:B10", `[{"type":"3_color_scale","criteria":"=","min_type":"min","mid_type":"percentile","max_type":"max","min_color":"#F8696B","mid_color":"#FFEB84","max_color":"#63BE7B"}]`)

 Enumeration Value              | Description
--------------------------------+-------------------------------------------------------------
 bottomLeft (Bottom Left Pane)  | Bottom left pane, when both vertical and horizontal
                                | splits are applied.
                                |
                                | This value is also used when only a horizontal split has
                                | been applied, dividing the pane into upper and lower
                                | regions. In that case, this value specifies the bottom
                                | pane.
                                |
bottomRight (Bottom Right Pane) | Bottom right pane, when both vertical and horizontal
                                | splits are applied.
                                |
topLeft (Top Left Pane)         | Top left pane, when both vertical and horizontal splits
                                | are applied.
                                |
                                | This value is also used when only a horizontal split has
                                | been applied, dividing the pane into upper and lower
                                | regions. In that case, this value specifies the top pane.
                                |
                                | This value is also used when only a vertical split has
                                | been applied, dividing the pane into right and left
                                | regions. In that case, this value specifies the left pane
                                |

                                | pane.

Pane state type is restricted to the values supported currently listed in the following table: 

 Enumeration Value              | Description
--------------------------------+-------------------------------------------------------------
 frozen (Frozen)                | Panes are frozen, but were not split being frozen. In
                                | this state, when the panes are unfrozen again, a single
                                | pane results, with no split.
                                |
                                | In this state, the split bars are not adjustable.
                                |
 split (Split)                  | Panes are split, but not frozen. In this state, the split
                                | bars are adjustable by the user.

x_split (Horizontal Split Position): Horizontal position of the split, in 1/20th of a point; 0 (zero) if none. If the pane is frozen, this value indicates the number of columns visible in the top pane.

y_split (Vertical Split Position): Vertical position of the split, in 1/20th of a point; 0 (zero) if none. If the pane is frozen, this value indicates the number of rows visible in the left pane. The possible values for this attribute are defined by the W3C XML Schema double datatype.

top_left_cell: Location of the top left visible cell in the bottom right pane (when in Left-To-Right mode).

sqref (Sequence of References): Range of the selection. Can be non-contiguous set of ranges.

An example of how to freeze column A in the Sheet1 and set the active cell on Sheet1!K16: 

f.SetPanes("Sheet1", `{"freeze":true,"split":false,"x_split":1,"y_split":0,"top_left_cell":"B1","active_pane":"topRight","panes":[{"sqref":"K16","active_cell":"K16","pane":"topRight"}]}`)

An example of how to freeze rows 1 to 9 in the Sheet1 and set the active cell ranges on Sheet1!A11:XFD11: 

f.SetPanes("Sheet1", `{"freeze":true,"split":false,"x_split":0,"y_split":9,"top_left_cell":"A34","active_pane":"bottomLeft","panes":[{"sqref":"A11:XFD11","active_cell":"A11","pane":"bottomLeft"}]}`)

An example of how to create split panes in the Sheet1 and set the active cell on Sheet1!J60: 

f.SetPanes("Sheet1", `{"freeze":false,"split":true,"x_split":3270,"y_split":1800,"top_left_cell":"N57","active_pane":"bottomLeft","panes":[{"sqref":"I36","active_cell":"I36"},{"sqref":"G33","active_cell":"G33","pane":"topRight"},{"sqref":"J60","active_cell":"J60","pane":"bottomLeft"},{"sqref":"O60","active_cell":"O60","pane":"bottomRight"}]}`)
