# 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 1.25.0 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(); e
```
