在Go中编写现有的Excel文件

Question

There's any way to write on an existing Excel file in Go?, i've tried with some libraries that are basically to create the excel file from blank but i need to write on an existing file.

Any help is appreciated, Thanks.

UPDATE Using the excel package @Marc recommended, i got this error:

CODE This is the code i tried to use.

package main

import (
    "fmt"
    "github.com/nivrrex/excel"
)

func main() {

    e := &excel.Excel{Visible: false, Readonly: false, Saved: true}
    filePath := "test.xlsx"
    e.Open(filePath)

    //Print
    fmt.Println(e.Cells(1, 1))
    e.Sheet(1)
    e.CellsWrite("Hello", 2, 2)
    e.Save()
    e.Close()

}

You should have a look at this package, which is built on top of the ole bindings for go that can be found here

The CellsWrite function should do what you want:

func (this *Excel) CellsWrite(value string, row int, column int) (err error)
