Use the excelize library in Go to create new Excel workbooks, set cell values, and save files with minimal code.

Use the github.com/xuri/excelize/v2 library to create, read, and write Excel files by initializing a workbook, manipulating cells, and saving the file.

package main

import (
	"fmt"
	"github.com/xuri/excelize/v2"
)

func main() {
	f := excelize.NewFile()
	index, _ := f.NewSheet("Sheet2")
	f.SetCellValue("Sheet2", "A1", "Hello world.")
	f.SetCellValue("Sheet2", "B1", "153")
	f.SetActiveSheet(index)
	if err := f.SaveAs("Book1.xlsx"); err != nil {
		fmt.Println(err)
	}
}
  1. Install the library by running go get github.com/xuri/excelize/v2.
  2. Create a new workbook instance using f := excelize.NewFile().
  3. Set a cell value with f.SetCellValue("Sheet1", "A1", "Your Text").
  4. Save the file to disk using f.SaveAs("output.xlsx").
