Go language reading and writing Excel

What's excelize? Golang writes a class library that is used to manipulate office Excel documents, based on the ECMA-376 office OpenXML standard. You can use it to read, write to XLSX files. Compared to other open source class libraries, Excelize supports writing documents with pictures (tables), supports inserting pictures into Excel, and does not lose the chart style after saving.

Installation

go get github.com/360EntSecGroup-Skylar/excelize

Create XLSX

package mainimport (    "fmt"    "github.com/360EntSecGroup-Skylar/excelize")func main() {    xlsx := excelize.NewFile()    // Create a new sheet.    index := xlsx.NewSheet("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(index)    // Save xlsx file by the given path.    err := xlsx.SaveAs("./Book1.xlsx")    if err != nil {        fmt.Println(err)    }}

Read and write existing documents

package mainimport (    "fmt"    "github.com/360EntSecGroup-Skylar/excelize")func main() {    xlsx, err := excelize.OpenFile("./Book1.xlsx")    if err != nil {        fmt.Println(err)        return    }    // Get value from cell by given worksheet name and axis.    cell := xlsx.GetCellValue("Sheet1", "B2")    fmt.Println(cell)    // Get all the rows in the Sheet1.    rows := xlsx.GetRows("Sheet1")    for _, row := range rows {        for _, colCell := range row {            fmt.Print(colCell, "\t")        }        fmt.Println()    }}

Insert a chart into Excel

Package Mainimport ("FMT" "Github.com/360entsecgroup-skylar/excelize") func main () {categories: = Map[string]str ing{"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. NewFile () 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": "Col3dclustered", "series": [{"Name": "sheet1! $A $ $", "categories": "sheet1! $B $: $D $ 1 "Values": "sheet1! $B $: $D $"},{"name": "sheet1! $A $", "categories": "sheet1! $B $: $D $", "values": "sheet1! $B $: $D $ "},{" name ":" sheet1! $A $4 "," categories ":" sheet1! $B $: $D $ "," values ":" sheet1! $B $4: $D $4 "}]," title ": {" name ":"    Fruit 3D Clustered Column Chart "}} ')//Save xlsx file by the given path. ERR: = xlsx. SaveAs ("./book1.xlsx") if err! = Nil {fmt. Println(ERR)}} 

Insert a picture into Excel

package mainimport ("Fmt" _ "Image/gif" _ "Image/jpeg" _ "Image/png" "github.com /360entsecgroup-skylar/excelize ") Func main () {xlsx, err: = Excelize. OpenFile ("./book1.xlsx") if err! = Nil {fmt. PRINTLN (ERR) return}//Insert a picture. Err = xlsx. AddPicture ("Sheet1", "A2", "./image1.png", "" ") if err! = Nil {fmt. PRINTLN (ERR)}//Insert a picture to worksheet 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 of offset in the cell with printing support. Err = xlsx. AddPicture ("Sheet1", "H2", "./image3.gif", "{" X_offset ":", "Y_offset": Ten, "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)}}
