Hi @dingweihua, file corrupted caused by missing top_left_cell when set panes, specify the location of the top-left visible cell in the bottom right pane:

if err = f.SetPanes(defaultSheet, `{"freeze":true,"split": false,"x_split":0,"y_split":`+strconv.Itoa(titleLineNum+1)+`,"top_left_cell":"A3"}`); err != nil {
    panic(err)
}

@xuri Yes, it's fixed! Thanks very much!

`package main

import (
"fmt"

"github.com/xuri/excelize/v2"

)

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 spreadsheet by the given path.
if err := f.SaveAs("Book1.xlsx"); err != nil {
fmt.Println(err)
}
}`

official example has the same problem.I have no idea , please help @xuri

Hi @MrWrong77, which version of the Excelize library and Go language version are you using?
