## Introduction
|
|
|
|
Excelize is a library written in pure Golang 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 1.8 or later. The full API docs can be seen using go's built-in documentation tool, or online at [godoc.org](https://godoc.org/github.com/Luxurioust/excelize).

|
## Basic Usage
|
|
|
|
### Installation
|
|
|
|
```go
|
|
go get github.com/Luxurioust/excelize
|
|
```
|
|
|
|
### Create XLSX file
|
|
|
|
Here is a minimal example usage that will create XLSX file.
|
|
|
|
```go
|
|
package main
|
|
|
|
import (
|
|
"fmt"
|
|
"os"
|
|
|
|
"github.com/Luxurioust/excelize"
|
|
)
|
|
|
|
func main() {
|
|
xlsx := excelize.CreateFile()
|
|
// Create a new sheet.
|
|
xlsx.NewSheet(2, "Sheet2")
|
|
// Set value of a cell.
|
|
xlsx.SetCellValue("Sheet2", "A2", "Hello world.")
|
|
xlsx.SetCellValue("Sheet1", "B2", 100)
|
|
// Set active sheet of the workbook.
|
|
xlsx.SetActiveSheet(2)
|
|
// Save xlsx file by the given path.
|
|
err := xlsx.WriteTo("./Workbook.xlsx")
|
|
if err != nil {
|
|
fmt.Println(err)
|
|
os.Exit(1)
|
|
}
|
|
}
|
|
```
|
|
|
|
### Reading XLSX file
|
|
|
|
The following constitutes the bare to read a XLSX document.
|
|
|
|
```go
|
|
package main
|
|
|
|
import (
|
|
"fmt"
|
|
"os"
|
|
"strconv"
|
|
|
|
"github.com/Luxurioust/excelize"
|
|
)
|
|
|
|
func main() {
|
|
xlsx, err := excelize.OpenFile("./Workbook.xlsx")
|
|
if err != nil {
|
|
fmt.Println(err)
|
|
os.Exit(1)
|
|
}
|
|
// Get value from cell by given sheet index and axis.
|
|
cell := xlsx.GetCellValue("Sheet1", "B2")
|
|
fmt.Println(cell)
|
|
// Get sheet index.
|
|
index := xlsx.GetSheetIndex("Sheet2")
|
|
// Get all the rows in a sheet.
|
|
rows := xlsx.GetRows("sheet" + strconv.Itoa(index))
|
|
for _, row := range rows {
|
|
for _, colCell := range row {
|
|
fmt.Print(colCell, "\t")
|
|
}
|
|
fmt.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 sheet at all.
|
|
|
|
|
|
|
|
```go
|
|
package main
|
|
|
|
import (
|
|
"fmt"
|
|
"os"
|
|
|
|
"github.com/Luxurioust/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}
|
|
xlsx := excelize.CreateFile()
|
|
for k, v := range categories {
|
|
xlsx.SetCellValue("Sheet1", k, v)
|
|
}
|
|
for k, v := range values {
|
|
xlsx.SetCellValue("Sheet1", k, v)
|
|
}
|
|
xlsx.AddChart("Sheet1", "E1", `{"type":"bar3D","series":[{"name":"=Sheet1!$A$2","categories":"=Sheet1!$B$1:$D$1","values":"=Sheet1!$B$2:$D$2"},{"name":"=Sheet1!$A$2","categories":"=Sheet1!$B$1:$D$1","values":"=Sheet1!$B$3:$D$3"},{"name":"=Sheet1!$A$3","categories":"=Sheet1!$B$1:$D$1","values":"=Sheet1!$B$4:$D$4"}],"title":{"name":"Fruit 3D Line Chart"}}`)
|
|
// Save xlsx file by the given path.
|
|
err := xlsx.WriteTo("./Workbook.xlsx")
|
|
if err != nil {
|
|
fmt.Println(err)
|
|
os.Exit(1)
|
|
}
|
|
}
|
|
```
|
|
|
|
### Add picture to XLSX file
|
|
|
|
```go
|
|
package main
|
|
|
|
import (
|
|
"fmt"
|
|
"os"
|
|
_ "image/gif"
|
|
_ "image/jpeg"
|
|
_ "image/png"
|
|
|
|
"github.com/Luxurioust/excelize"
|
|
)
|
|
|
|
func main() {
|
|
xlsx, err := excelize.OpenFile("./Workbook.xlsx")
|
|
if err != nil {
|
|
fmt.Println(err)
|
|
os.Exit(1)
|
|
}
|
|
// Insert a picture.
|
|
err = xlsx.AddPicture("Sheet1", "A2", "./image1.png", "")
|
|
if err != nil {
|
|
fmt.Println(err)
|
|
}
|
|
// Insert a picture to sheet with scaling.
|
|
err = xlsx.AddPicture("Sheet1", "D2", "./image2.jpg", `{"x_scale": 0.5, "y_scale": 0.5}`)
|
|
if err != nil {
|
|
fmt.Println(err)
|
|
}
|
|
// Insert a picture offset in the cell with printing support.
|
|
err = xlsx.AddPicture("Sheet1", "H2", "./image3.gif", `{"x_offset": 15, "y_offset": 10, "print_obj": true, "lock_aspect_ratio": false, "locked": false}`)
|
|
if err != nil {
|
|
fmt.Println(err)
|
|
}
|
|
// Save the xlsx file with the origin path.
|
|
err = xlsx.Save()
|
|
if err != nil {
|
|
fmt.Println(err)
|
|
os.Exit(1)
|
|
}
|
|
}
|
|
```
