Excelize

Introduction

Excelize is a library written in pure Go providing a set of functions that allow you to write to and read from XLAM / XLSM / XLSX / XLTM / XLTX files. Supports reading and writing spreadsheet documents generated by Microsoft Excel™ 2007 and later. Supports complex components by high compatibility, and provided streaming API for generating or reading data from a worksheet with huge amounts of data. This library needs Go version 1.16 or later. The full 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/xuri/excelize
  • If your packages are managed using Go Modules, please install with following command.
go get github.com/xuri/excelize/v2
Create spreadsheet

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

package main

import (
    "fmt"

    "github.com/xuri/excelize/v2"
)

func main() {
    f := excelize.NewFile()
    defer func() {
        if err := f.Close(); err != nil {
            fmt.Println(err)
        }
    }()
    // Create a new sheet.
    index, err := f.NewSheet("Sheet2")
    if err != nil {
        fmt.Println(err)
        return
    }
    // 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 spreadsheet by the given path.
    if err := f.SaveAs("Book1.xlsx"); err != nil {
        fmt.Println(err)
    }
}
Reading spreadsheet

The following constitutes the bare to read a spreadsheet document.

package main

import (
    "fmt"

    "github.com/xuri/excelize/v2"
)

func main() {
    f, err := excelize.OpenFile("Book1.xlsx")
    if err != nil {
        fmt.Println(err)
        return
    }
    defer func() {
        // Close the spreadsheet.
        if err := f.Close(); err != nil {
            fmt.Println(err)
        }
    }()
    // Get value from cell by given worksheet name and cell reference.
    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")
    if err != nil {
        fmt.Println(err)
        return
    }
    for _, row := range rows {
        for _, colCell := range row {
            fmt.Print(colCell, "\t")
        }
        fmt.Println()
    }
}
Add chart to spreadsheet file

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

IndexedColorMapping is the table of default mappings from indexed color value to RGB value. Note that 0-7 are redundant of 8-15 to preserve backwards compatibility. A legacy indexing scheme for colors that is still required for some records, and for backwards compatibility with legacy formats. This element contains a sequence of RGB color values that correspond to color indexes (zero-based). When using the default indexed color palette, the values are not written out, but instead are implied. When the color palette has been modified from default, then the entire color palette is written out.

The optional parameter "AutoFit" specifies if you make image size auto-fits the cell, the default value of that is 'false'.

The optional parameter "Hyperlink" specifies the hyperlink of the image.

The optional parameter "HyperlinkType" defines two types of hyperlink "External" for website or "Location" for moving to one of the cells in this workbook. When the "HyperlinkType" is "Location", coordinates need to start with "#".

The optional parameter "Positioning" defines two types of the position of an image in an Excel spreadsheet, "oneCell" (Move but don't size with cells) or "absolute" (Don't move or size with cells). If you don't set this parameter, the default positioning is move and size with cells.

The optional parameter "PrintObject" indicates whether the image is printed when the worksheet is printed, the default value of that is 'true'.

The optional parameter "LockAspectRatio" indicates whether lock aspect ratio for the image, the default value of that is 'false'.

The optional parameter "Locked" indicates whether lock the image. Locking an object has no effect unless the sheet is protected.

The optional parameter "OffsetX" specifies the horizontal offset of the image with the cell, the default value of that is 0.

The optional parameter "ScaleX" specifies the horizontal scale of images, the default value of that is 1.0 which presents 100%.

The optional parameter "OffsetY" specifies the vertical offset of the image with the cell, the default value of that is 0.

The optional parameter "ScaleY" specifies the vertical scale of images, the default value of that is 1.0 which presents 100%.

func (*File) AddSparkline 

func (f *File) AddSparkline(sheet string, opts *SparklineOptions) 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.SparklineOptions{
    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
 Axis        | Used to specify if show horizontal axis
 Reverse     | Used to specify if enable plot data right-to-left
 SeriesColor | An RGB Color is specified as RRGGBB

func (*File) AddTable 

func (f *File) AddTable(sheet string, table *Table) error

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

err := f.AddTable("Sheet1", &excelize.Table{Range: "A1:D5"})

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

disable := false
err := f.AddTable("Sheet2", &excelize.Table{
    Range:             "F2:H6",
    Name:              "table",
    StyleName:         "TableStyleMedium2",
    ShowFirstColumn:   true,
    ShowLastColumn:    true,
    ShowRowStripes:    &disable,
    ShowColumnStripes: 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 range reference that can't have an intersection.

Name: The name of the table, in the same worksheet name of the table should be unique, starts with a letter or underscore (_), doesn't include a space or character, and should be no more than 255 characters

StyleName: The built-in table style names 

TableStyleLight1 - TableStyleLight21
TableStyleMedium1 - TableStyleMedium28
TableStyleDark1 - TableStyleDark11

func (*File) AddVBAProject 

func (f *File) AddVBAProject(file []byte) error

AddVBAProject provides the method to add vbaProject.bin file which contains functions and/or macros. The file extension should be XLSM or XLTM. For example: 

codeName := "Sheet1"
if err := f.SetSheetProps("Sheet1", &excelize.SheetPropsOptions{
    CodeName: &codeName,
}); err != nil {
    fmt.Println(err)
    return
}
file, err := os.ReadFile("vbaProject.bin")
if err != nil {
    fmt.Println(err)
    return
}
if err := f.AddVBAProject(file); err != nil {
    fmt.Println(err)
    return
}
if err := f.SaveAs("macros.xlsm"); err != nil {
    fmt.Println(err)
    return
}

func (*File) AutoFilter 

func (f *File) AutoFilter(sheet, rangeRef string, opts []AutoFilterOptions) error

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

err := f.AutoFilter("Sheet1", "A1:D4", []excelize.AutoFilterOptions{})

Filter data in an auto filter: 

err := f.AutoFilter("Sheet1", "A1:D4", []excelize.AutoFilterOptions{
    {Column: "B", Expression: "x != blanks"},
})

Column defines the filter columns in an auto filter 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 function. 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*      // doesn't begin with b
x == *b      // ends with b
x != *b      // doesn't 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) CalcCellValue 

func (f *File) CalcCellValue(sheet, cell string, opts ...Options) (result string, err error)

CalcCellValue provides a function to get calculated cell value. This feature is currently in working processing. Iterative calculation, implicit intersection, explicit intersection, array formula, table formula and some other formulas are not supported currently.

func (*File) SetConditionalFormat 

func (f *File) SetConditionalFormat(sheet, rangeRef string, opts []ConditionalFormatOptions) error

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
               | MinValue
               | MaxValue
 date          | Criteria
               | Value
               | MinValue
               | MaxValue
 time_period   | Criteria
 text          | Criteria
               | Value

               | MinValue
               | MaxValue
               | MinColor
               | MaxColor
 3_color_scale | MinType
               | MidType
               | MaxType
               | MinValue
               | MidValue
               | MaxValue
               | MinColor
               | MidColor
               | MaxColor
 data_bar      | MinType
               | MaxType
               | MinValue
               | MaxValue
               | BarBorderColor
               | BarColor
               | BarDirection
               | BarOnly
               | BarSolid
 icon_set      | IconStyle
               | ReverseIcons
               | IconsOnly
 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: 

err := f.SetConditionalFormat("Sheet1", "D1:D10",
    []excelize.ConditionalFormatOptions{
        {
            Type:     "cell",
            Criteria: ">",
            Format:   format,
            Value:    "6",
        },
    },
)

The value property can also be an cell reference: 

err := f.SetConditionalFormat("Sheet1", "D1:D10",
    []excelize.ConditionalFormatOptions{
        {
            Type:     "cell",
            Criteria: ">",
            Format:   format,
            Value:    "$C$1",
        },
    },
)

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 function in the same way as cell formats: 

format, err := f.NewConditionalStyle(
    &excelize.Style{
        Font: &excelize.Font{Color: "9A0511"},
        Fill: excelize.Fill{
            Type: "pattern", Color: []string{"FEC7CE"}, Pattern: 1,
        },
    },
)
if err != nil {
    fmt.Println(err)
}
err = f.SetConditionalFormat("Sheet1", "D1:D10",
    []excelize.ConditionalFormatOptions{
        {Type: "cell", Criteria: ">", Format: format, Value: "6"},
    },
)

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(
    &excelize.Style{
        Font: &excelize.Font{Color: "9A0511"},
        Fill: excelize.Fill{
            Type: "pattern", Color: []string{"#FEC7CE"}, Pattern: 1,
        },
    },
)

// Light yellow format for neutral conditional.
format2, err := f.NewConditionalStyle(
    &excelize.Style{
        Font: &excelize.Font{Color: "9B5713"},
        Fill: excelize.Fill{
            Type: "pattern", Color: []string{"FEEAA0"}, Pattern: 1,
        },
    },
)

// Light green format for good conditional.
format3, err := f.NewConditionalStyle(
    &excelize.Style{
        Font: &excelize.Font{Color: "09600B"},
        Fill: excelize.Fill{
            Type: "pattern", Color: []string{"C7EECF"}, Pattern: 1,
        },
    },
)

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

// Highlight cells rules: between...
err := f.SetConditionalFormat("Sheet1", "A1:A10",
    []excelize.ConditionalFormatOptions{
        {
            Type:     "cell",
            Criteria: "between",
            Format:   format,
            MinValue: 6",
            MaxValue: 8",
        },
    },
)

type: MaxValue - The 'MaxValue' 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...
err := f.SetConditionalFormat("Sheet1", "A1:A10",
    []excelize.ConditionalFormatOptions{
        {
            Type:         "average",
            Criteria:     "=",
            Format:       format1,
            AboveAverage: true,
        },
    },
)

// Top/Bottom rules: Below Average...
err := f.SetConditionalFormat("Sheet1", "B1:B10",
    []excelize.ConditionalFormatOptions{
        {
            Type:         "average",
            Criteria:     "=",
            Format:       format2,
            AboveAverage: false,
        },
    },
)

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

// Highlight cells rules: Duplicate Values...
err := f.SetConditionalFormat("Sheet1", "A1:A10",
    []excelize.ConditionalFormatOptions{
        {Type: "duplicate", Criteria: "=", Format: format},
    },
)

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

// Highlight cells rules: Not Equal To...
err := f.SetConditionalFormat("Sheet1", "A1:A10",
    []excelize.ConditionalFormatOptions{
        {Type: "unique", Criteria: "=", Format: 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.
err := f.SetConditionalFormat("Sheet1", "H1:H10",
    []excelize.ConditionalFormatOptions{
        {
            Type:     "top",
            Criteria: "=",
            Format:   format,
            Value:    "6",
        },
    },
)

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

err := f.SetConditionalFormat("Sheet1", "A1:A10",
    []excelize.ConditionalFormatOptions{
        {
            Type:     "top",
            Criteria: "=",
            Format:   format,
            Value:    "6",
            Percent:  true,
        },
    },
)

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.
err := f.SetConditionalFormat("Sheet1", "A1:A10",
    []excelize.ConditionalFormatOptions{
        {
            Type:     "2_color_scale",
            Criteria: "=",
            MinType:  "min",
            MaxType:  "max",
            MinColor: "#F8696B",
            MaxColor: "#63BE7B",
        },
    },
)

This conditional type can be modified with MinType, MaxType, MinValue, MaxValue, MinColor and MaxColor, 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.
err := f.SetConditionalFormat("Sheet1", "A1:A10",
    []excelize.ConditionalFormatOptions{
        {
            Type:     "3_color_scale",
            Criteria: "=",
            MinType:  "min",
            MidType:  "percentile",
            MaxType:  "max",
            MinColor: "#F8696B",
            MidColor: "#FFEB84",
            MaxColor: "#63BE7B",
        },
    },
)

This conditional type can be modified with MinType, MidType, MaxType, MinValue, MidValue, MaxValue, MinColor, MidColor and MaxColor, see below.

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

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

// Data Bars: Gradient Fill.
err := f.SetConditionalFormat("Sheet1", "K1:K10",
    []excelize.ConditionalFormatOptions{
        {
            Type:     "data_bar",
            Criteria: "=",
            MinType:  "min",
            MaxType:  "max",
            BarColor: "#638EC6",
        },
    },
)

The available min/mid/max types are: 

min        (for MinType only)
num
percent
percentile
formula
max        (for MaxType only)

MidType - Used for 3_color_scale. Same as MinType, see above.

MaxType - Same as MinType, see above.

MinValue - The MinValue and MaxValue properties are available when the conditional formatting type is 2_color_scale, 3_color_scale or data_bar.

type StreamWriter 

type StreamWriter struct {
	Sheet   string
	SheetID int
	// contains filtered or unexported fields
}

StreamWriter defined the type of stream writer.

func (*StreamWriter) AddTable 

func (sw *StreamWriter) AddTable(table *Table) error

AddTable creates an Excel table for the StreamWriter using the given cell range and format set. For example, create a table of A1:D5: 

err := sw.AddTable(&excelize.Table{Range: "A1:D5"})

Create a table of F2:H6 with format set: 

disable := false
err := sw.AddTable(&excelize.Table{
    Range:             "F2:H6",
    Name:              "table",
    StyleName:         "TableStyleMedium2",
    ShowFirstColumn:   true,
    ShowLastColumn:    true,
    ShowRowStripes:    &disable,
    ShowColumnStripes: true,
})

Note that the table must be at least two lines including the header. The header cells must contain strings and must be unique.

Currently, only one table is allowed for a StreamWriter. AddTable must be called after the rows are written but before Flush.

See File.AddTable for details on the table format.

func (*StreamWriter) Flush 

func (sw *StreamWriter) Flush() error

Flush ending the streaming writing process.

func (*StreamWriter) InsertPageBreak 

func (sw *StreamWriter) InsertPageBreak(cell string) error

func (*StreamWriter) SetColWidth 

func (sw *StreamWriter) SetColWidth(min, max int, width float64) error

SetColWidth provides a function to set the width of a single column or multiple columns for the StreamWriter. Note that you must call the 'SetColWidth' function before the 'SetRow' function. For example set the width column B:C as 20: 

err := sw.SetColWidth(2, 3, 20)

func (*StreamWriter) SetPanes 

func (sw *StreamWriter) SetPanes(panes *Panes) error

SetPanes provides a function to create and remove freeze panes and split panes by giving panes options for the StreamWriter. Note that you must call the 'SetPanes' function before the 'SetRow' function.

func (*StreamWriter) SetRow 

func (sw *StreamWriter) SetRow(cell string, values []interface{}, opts ...RowOpts) error

SetRow writes an array to stream rows by giving starting cell reference and a pointer to an array of values. Note that you must call the 'Flush' function to end the streaming writing process.

As a special case, if Cell is used as a value, then the Cell.StyleID will be applied to that cell.

	// ShowZeros indicating whether to "show a zero in cells that have zero
	// value". When using a formula to reference another cell which is empty,
	// the referenced value becomes 0 when the flag is true. (Default setting
	// is true.)
	ShowZeros *bool
	// TopLeftCell specifies a location of the top left visible cell Location
	// of the top left visible cell in the bottom right pane (when in
	// Left-to-Right mode).
	TopLeftCell *string
	// View indicating how sheet is displayed, by default it uses empty string
	// available options: normal, pageLayout, pageBreakPreview
