Excelize is a library written in pure Go providing a set of functions that allow you to write to and read from XLSX files. It supports reading and writing XLSX file generated by Microsoft Excel™ 2007 and later. It supports saving a file without losing original charts of XLSX. This library needs Go version 1.10 or later. The full API docs can be seen using Go's built-in documentation tool, or online at godoc.org and docs reference.

Create XLSX File
Here is a minimal example usage that will create an XLSX file.
package main
import "github.com/360EntSecGroup-Skylar/excelize"
func main() {
f := excelize.NewFile()
index := f.NewSheet("Sheet2")
f.SetCellValue("Sheet2", "A2", "Hello world.")
f.SetCellValue("Sheet1", "B2", 100)
f.SetActiveSheet(index)
if err := f.SaveAs("Book1.xlsx"); err != nil {
println(err.Error())
}
}
Reading XLSX File
The following constitutes the bar to read an XLSX document.
package main
import "github.com/360EntSecGroup-Skylar/excelize"
func main() {
f, err := excelize.OpenFile("Book1.xlsx")
if err != nil {
println(err.Error())
return
}
cell, err := f.GetCellValue("Sheet1", "B2")
if err != nil {
println(err.Error())
return
}
println(cell)
rows, err := f.GetRows("Sheet1")
for _, row := range rows {
for _, colCell := range row {
print(colCell, "\t")
}
println()
}
}
Add Chart to XLSX File
With Excelize, chart generation and management is as easy as a few lines of code. You can build charts based off data in your worksheet or generate charts without any data in your worksheet at all.

package main
import "github.com/360EntSecGroup-Skylar/excelize"
func main() {
categories := map[string]string{"A2": "Small", "A3": "Normal",
"A4": "Large", "B1": "Apple", "C1": "Orange", "D1": "Pear"}
values := map[string]int{"B2": 2, "C2": 3, "D2": 3, "B3": 5,
"C3": 2, "D3": 4, "B4": 6, "C4": 7, "D4": 8}
f := excelize.NewFile()
for k, v := range categories {
f.SetCellValue("Sheet1", k, v)
}
for k, v := range values {
f.SetCellValue("Sheet1", k, v)
}
if err := f.AddChart("Sheet1", "E1", `{"type":"col3DClustered",
"series":[{"name":"Sheet1!$A$2","categories":"Sheet1!$B$1:$D$1",
"values":"Sheet1!$B$2:$D$2"},{"name":"Sheet1!$A$3","categories":"Sheet1!$B$1:$D$1",
"values":"Sheet1!$B$3:$D$3"},{"name":"Sheet1!$A$4","categories":"Sheet1!$B$1:$D$1",
"values":"Sheet1!$B$4:$D$4"}],"title":{"name":"Fruit 3D Clustered Column Chart"}}`);
err != nil {
println(err.Error())
return
}
if err := f.SaveAs("Book1.xlsx"); err != nil {
println(err.Error())
}
}
Add picture to XLSX file:
package main
import (
_ "image/gif"
_ "image/jpeg"
_ "image/png"
"github.com/360EntSecGroup-Skylar/excelize"
)
func main() {
f, err := excelize.OpenFile("Book1.xlsx")
if err != nil {
println(err.Error())
return
}
if err := f.AddPicture("Sheet1", "A2", "image.png", ""); err != nil {
println(err.Error())
}
if err := f.AddPicture("Sheet1", "D2", "image.jpg",
`{"x_scale": 0.5, "y_scale": 0.5}`); err != nil {
println(err.Error())
}
if err := f.AddPicture("Sheet1", "H2", "image.gif",
`{"x_offset": 15, "y_offset": 10, "print_obj": true,
"lock_aspect_ratio": false, "locked": false}`); err != nil {
println(err.Error())
}
if err = f.Save(); err != nil {
println(err.Error())
}
}
