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 / XLSM / XLTM 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 1.10 or later. The full API docs can be seen using go's built-in documentation tool, or online at go.dev and docs reference.
Basic Usage
Installation
go get github.com/360EntSecGroup-Skylar/excelize
- If your package management with Go Modules, please install with following command.
go get github.com/360EntSecGroup-Skylar/excelize/v2
Create spreadsheet
Here is a minimal example usage that will create spreadsheet file.
package main import ( "fmt" "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 { fmt.Println(err) } }
Reading spreadsheet
The following constitutes the bare to read a spreadsheet document.
package main import ( "fmt" "github.com/360EntSecGroup-Skylar/excelize" ) func main() { f, err := excelize.OpenFile("Book1.xlsx") if err != nil { fmt.Println(err) return } // Get value from cell by given worksheet name and axis. 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") 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 off data in your worksheet or generate charts without any data in your worksheet at all.
package main import ( "fmt" "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 { fmt.Println(err) return } // Save xlsx file by the given path. if err := f.SaveAs("Book1.xlsx"); err != nil { fmt.Println(err) } }
Add picture to spreadsheet file
package main import ( "fmt" _ "image/gif" _ "image/jpeg" _ "image/png" "github.com/360EntSecGroup-Skylar/excelize" ) func main() { f, err := excelize.OpenFile("Book1.xlsx") if err != nil { fmt.Println(err) return } // Insert a picture. if err := f.AddPicture("Sheet1", "A2", "image.png", ""); err != nil { fmt.Println(err) } // 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 { fmt.Println(err) } // 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 { fmt.Println(err) } // Save the xlsx file with the origin path. if err = f.Save(); err != nil { fmt.Println(err) } }
