Excelize

Introduction

Excelize is a library written in pure Go providing a set of functions that allow you to write to and read from XLSX files. Supports reading and writing XLSX file generated by Microsoft Excel™ 2007 and later. 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.

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"funcmain() {
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.iferr:=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"funcmain() {
f, err:=excelize.OpenFile("Book1.xlsx")
iferr!=nil {
println(err.Error())
return
}
// Get value from cell by given worksheet name and axis.cell, err:=f.GetCellValue("Sheet1", "B2")
iferr!=nil {
println(err.Error())
return
}
println(cell)
// Get all the rows in the Sheet1.rows, err:=f.GetRows("Sheet1")
for_, row:=rangerows {
for_, colCell:=rangerow {
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"funcmain() {
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()
fork, v:=rangecategories {
f.SetCellValue("Sheet1", k, v)
}
fork, v:=rangevalues {
f.SetCellValue("Sheet1", k, v)
}
iferr:=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.iferr:=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"
)
funcmain() {
f, err:=excelize.OpenFile("Book1.xlsx")
iferr!=nil {
println(err.Error())
return
}
// Insert a picture.iferr:=f.AddPicture("Sheet1", "A2", "image.png", ""); err!=nil {
println(err.Error())
}
// Insert a picture to worksheet with scaling.iferr:=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.iferr:=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.iferr=f.Save(); err!=nil {
println(err.Error())
}
}
