Excelize is a library written in pure Go and providing a set of functions that allow you to write to and read from XLSX files. Support reads and writes XLSX file generated by Microsoft Excel™ 2007 and later. Support save 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. GitHub: github.com/360EntSecGroup-Skylar/excelize Basic Usage
Installation - go get github.com/360EntSecGroup-Skylar/excelize
Create XLSX file
Here is a minimal example usage that will create XLSX file. - package main
-
-
import "github.com/360EntSecGroup-Skylar/excelize"
-
-
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 xlsx file by the given path.
-
if err := f.SaveAs("Book1.xlsx"); err != nil {
-
println(err.Error())
-
}
-
}
Reading XLSX file
The following constitutes the bare to read a 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
-
}
-
// Get value from cell by given worksheet name and axis.
-
cell, err := f.GetCellValue("Sheet1", "B2")
-
if err != nil {
-
println(err.Error())
-
return
-
}
-
println(cell)
-
// Get all the rows in the Sheet1.
-
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
-
}
-
// Save xlsx file by the given path.
-
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
-
}
-
// Insert a picture.
-
if err := f.AddPicture("Sheet1", "A2", "image.png", ""); err != nil {
-
println(err.Error())
-
}
-
// Insert a picture to worksheet with scaling.
-
if err := f.AddPicture("Sheet1", "D2", "image.jpg", `{"x_scale": 0.5, "y_scale": 0.5}`); err != nil {
-
println(err.Error())
-
}
-
// Insert a picture offset in the cell with printing support.
-
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())
-
}
-
// Save the xlsx file with the origin path.
-
if err = f.Save(); err != nil {
-
println(err.Error())
-
}
-
}
