import (
    . "github.com/Aspose-Cells/aspose-cells-go-cpp/v25"
)
// Load the source excel format.
workbook,_:= NewWorkbook_String("src_excel_file.xlsx")
// Save in required output format.
workbook.Save_String("output_excel_format.xlsx")

Convert Excel Formats to PDF with Compliance Level Settings

Go via C++ Excel Automation API supports conversion of Workbooks to PDF as well as support setting of compliance level and creation date. Developers can use PdfSaveOptions to set the PDF compliance. For conversion, API save method having PdfSaveOptions as parameter and speicified output file path.

Go via C++ Sample Code for Excel to PDF Conversion
package main

import (
    . "github.com/Aspose-Cells/aspose-cells-go-cpp/v25"
)

workbook, _ := NewWorkbook()
worksheets, _ := workbook.GetWorksheets()
worksheet, _ := worksheets.Get_Int(0)
cells, _ := worksheet.GetCells()
cell, _ := cells.Get_String("A1")
cell.PutValue_Int(5)
cell, _ = cells.Get_String("A2")
cell.PutValue_Int(15)
cell, _ = cells.Get_String("A3")
cell.PutValue_Int(25)
workbook.Save_String("HELLO_Convert.pdf")
println("Finish to convert to PDF , check .pdf file in output folder.")

Save Excel to Images

Go via C++ Code for Excel to Image Conversion
package main

import (
    . "github.com/Aspose-Cells/aspose-cells-go-cpp/v25"
)

 // Load the XLSX.
    workbook, _ := NewWorkbook("source-excel-file.xlsx")

// Access first worksheet.
    worksheets, _ := workbook.GetWorksheets()
    worksheet, _ := worksheets.Get_Int(0)

// Create image or print options object.
    imgOptions, _ := NewImageOrPrintOptions()

// Specify the image format. Below code is for JPEG
    imgOptions.SetImageType(ImageType_Jpeg)

// Specify horizontal and vertical resolution
    imgOptions.SetHorizontalResolution(200)
    imgOptions.SetVerticalResolution(200)

// Render the sheet with respect to specified image or print options.
    sheetRender, _ := NewSheetRender(worksheet, imgOptions)

// Get page count.
    pageCount, _ := sheetRender.GetPageCount()

// Render each page to jpeg image one by one.
    for i := int32(0); i < pageCount; i++ {
        data, _ := sheetRender.ToImage_Int(i)
        filename := "Image" + string(i) + ".jpg"
        file, _ := os.OpenFile(filename, os.O_WRONLY|os.O_CREATE|os.O_APPEND, 0644)
        defer file.Close()
        file.Write(data)
    }
