xls
Pure Golang xls library writen by MinkTech(chinese).
Thanks for contributions from Tamás Gulácsi.
English User please mailto Liu Ming
This is a xls library writen in pure Golang. Almostly it is translated from the libxls library in c.
It has just the reading function without the format.
Basic Usage
- Use Open function for open file
- Use OpenReader function for open xls from a reader
These methods will open a workbook object for reading, like
func (w *WorkBook) ReadAllCells() (res [][]string) {
for _, sheet := range w.Sheets {
w.PrepareSheet(sheet)
if sheet.MaxRow != 0 {
temp := make([][]string, sheet.MaxRow+1)
for k, row := range sheet.Rows {
data := make([]string, 0)
if len(row.Cols) > 0 {
for _, col := range row.Cols {
if uint16(len(data)) <= col.LastCol() {
data = append(data, make([]string, col.LastCol()-uint16(len(data))+1)...)
}
str := col.String(w)
for i := uint16(0); i < col.LastCol()-col.FirstCol()+1; i++ {
data[col.FirstCol()+i] = str[i]
}
}
temp[k] = data
}
}
res = append(res, temp...)
}
}
return
}

Open one xls file
Example ¶
if xlFile, err := Open("Table.xls", "utf-8"); err == nil {
fmt.Println(xlFile.Author)
}
Output:
func OpenReader ¶
func OpenReader(reader io.ReadSeeker, charset string) (wb *WorkBook, err error)

func (*WorkBook) GetSheet ¶
Get one sheet by its number
Example ¶
Output: read the content of first two cols in each row
if xlFile, err := Open("Table.xls", "utf-8"); err == nil {
if sheet1 := xlFile.GetSheet(0); sheet1 != nil {
fmt.Print("Total Lines ", sheet1.MaxRow, sheet1.Name)
col1 := sheet1.Row(0).Col(0)
col2 := sheet1.Row(0).Col(0)
for i := 0; i <= (int(sheet1.MaxRow)); i++ {
row1 := sheet1.Row(i)
col1 = row1.Col(0)
col2 = row1.Col(1)
fmt.Print("\n", col1, ",", col2)
}
}
}
Output:

type WorkSheet ¶
type WorkSheet struct {
Name string
//NOTICE: this is the max row number of the sheet, so it should be count -1
MaxRow uint16
// contains filtered or unexported fields
}
