# Excelize
## Introduction
Excelize is a library written in pure Go providing a set of functions that allow you to write to and read from XLAM / XLSM / XLSX / XLTM / XLTX files. Supports reading and writing spreadsheet documents generated by Microsoft Excel™ 2007 and later. Supports complex components by high compatibility, and provided streaming API for generating or reading data from a worksheet with huge amounts of data. This library needs Go version 1.16 or later. The full docs can be seen using go's built-in documentation tool, or online at [go.dev](https://pkg.go.dev/github.com/xuri/excelize/v2) and [docs reference](https://xuri.me/excelize/).
## Basic Usage
### Installation
```bash
go get github.com/xuri/excelize
```
- If your packages are managed using [Go Modules](https://go.dev/blog/using-go-modules), please install with following command.
```bash
go get github.com/xuri/excelize/v2
```
### Create spreadsheet
Here is a minimal example usage that will create spreadsheet file.
```go
package main
import (
"fmt"
"github.com/xuri/excelize/v2"
)
func main() {
f := excelize.NewFile()
defer func() {
if err := f.Close(); err != nil {
fmt.Println(err)
}
}()
// Create a new sheet.
index, err := f.NewSheet("Sheet2")
if err != nil {
fmt.Println(err)
return
}
// 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 spreadsheet by the given path.
if err := f.SaveAs("Book1.xlsx"); err != nil {
fmt.Println(err)
}
}
```
### Reading spreadsheet
The following constitutes the bare to read a spreadsheet document.
```go
package main
import (
"fmt"
"github.com/xuri/excelize/v2"
)
func main() {
f, err := excelize.OpenFile("Book1.xlsx")
if err != nil {
fmt.Println(err)
return
}
defer func() {
// Close the spreadsheet.
if err := f.Close(); err != nil {
fmt.Println(err)
}
}()
// Get value from cell by given worksheet name and cell reference.
cell, err := f.GetCellValue("Sheet1", "B2")
if err != nil {
fmt.Println(err)
return
}
fmt.Println(cell)
// Get all the rows in the Sheet1.
rows, err := f.GetRows("Sheet1")
if err != nil {
fmt.Println(err)
return
}
for _, row := range rows {
for _, colCell := range row {
fmt.Print(colCell, "\t")
}
fmt.Println()
}
}
```
### Add chart to spreadsheet file
With Excelize chart generation and management is as easy as a few lines of code. You can build charts based on data in your worksheet or generate charts without any data in your worksheet at all.
```go
package main
import (
"fmt"
"github.com/xuri/excelize/v2"
)
func main() {
f := excelize.NewFile()
defer func() {
if err := f.Close(); err != nil {
fmt.Println(err)
}
}()
for idx, row := range [][]interface{}{
{nil, "Apple", "Orange", "Pear"}, {"Small", 2, 3, 3},
{"Normal", 5, 2, 4}, {"Large", 6, 7, 8},
} {
cell, err := excelize.CoordinatesToCellName(1, idx+1)
if err != nil {
fmt.Println(err)
return
}
f.SetSheetRow("Sheet1", cell, &row)
}
if err := f.AddChart("Sheet1", "E1", &excelize.Chart{
Type: excelize.Col3DClustered,
Series: []excelize.ChartSeries{
{
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: excelize.ChartTitle{
Name: "Fruit 3D Clustered Column Chart",
},
}); err != nil {
fmt.Println(err)
return
}
// Save spreadsheet by the given path.
if err := f.SaveAs("Book1.xlsx"); err != nil {
fmt.Println(err)
}
}
```
### Add picture to spreadsheet file
```go
package main
import (
"fmt"
_ "image/gif"
_ "image/jpeg"
_ "image/png"
"github.com/xuri/excelize/v2"
)
func main() {
f, err := excelize.OpenFile("Book1.xlsx")
if err != nil {
fmt.Println(err)
return
}
defer func() {
// Close the spreadsheet.
if err := f.Close(); err != nil {
fmt.Println(err)
}
}()
// Insert a picture.
if err := f.AddPicture("Sheet1", "A2", "image.png", nil); err != nil {
fmt.Println(err)
}
// Insert a picture to worksheet with scaling.
if err := f.AddPicture("Sheet1", "D2", "image.jpg",
&excelize.GraphicOptions{ScaleX: 0.5, ScaleY: 0.5}); err != nil {
fmt.Println(err)
}
// Insert a picture offset in the cell with printing support.
enable, disable := true, false
if err := f.AddPicture("Sheet1", "H2", "image.gif",
&excelize.GraphicOptions{
PrintObject: &enable,
LockAspectRatio: false,
OffsetX: 15,
OffsetY: 10,
Locked: &disable,
}); err != nil {
fmt.Println(err)
}
// Save the spreadsheet with the origin path.
if err = f.Save(); err != nil {
fmt.Println(err)
}
}
```
