Excel, OpenOffice, Json, Csv ve Html Dosyalarını C++ ile Yükleme ve Yönetme

Yeni Bir Çalışma Kitabı Oluşturma

Aşağıdaki örnek sıfırdan yeni bir çalışma kitabı oluşturur.

#include <iostream>
#include "Aspose.Cells.h"

using namespace Aspose::Cells;

int main()
{
    Aspose::Cells::Startup();

    // Source directory path
    U16String srcDir(u"..\\Data\\01_SourceDirectory\\");

    try
    {
        // Create a License object
        License license;

        // Set the license of Aspose.Cells to avoid the evaluation limitations
        license.SetLicense(srcDir + u"Aspose.Cells.lic");
    }
    catch (const std::exception& ex)
    {
        std::cerr << ex.what() << std::endl;
    }

    // Instantiate a Workbook object that represents Excel file.
    Workbook wb;

    // When you create a new workbook, a default "Sheet1" is added to the workbook.
    Worksheet sheet = wb.GetWorksheets().Get(0);

    // Access the "A1" cell in the sheet.
    Cell cell = sheet.GetCells().Get(u"A1");

    // Input the "Hello World!" text into the "A1" cell
    cell.PutValue(u"Hello World!");

    // Save the Excel file.
    wb.Save(srcDir + u"MyBook_out.xlsx");

    Aspose::Cells::Cleanup();

    return 0;
}

Bir Dosya Açma ve Kaydetme

Aspose.Cells for C++ ile Excel dosyalarını açmak, kaydetmek ve yönetmek oldukça basittir.

#include <iostream>
#include "Aspose.Cells.h"
using namespace Aspose::Cells;

int main()
{
    Aspose::Cells::Startup();

    // Source directory path
    U16String srcDir(u"..\\Data\\01_SourceDirectory\\");

    // Output directory path
    U16String outDir(u"..\\Data\\02_OutputDirectory\\");

    // Path of input Excel file
    U16String inputFilePath = srcDir + u"Book1.xlsx";

    // Path of output Excel file
    U16String outputFilePath = outDir + u"dest.xlsx";

    // Create a Workbook object and open an Excel file using its file path
    Workbook workbook1(inputFilePath);

    // Adding new sheet
    WorksheetCollection sheets = workbook1.GetWorksheets();
    Worksheet sheet = sheets.Add(u"MySheet");

    // Setting active sheet
    sheets.SetActiveSheetIndex(1);

    // Setting values
    Cells cells = sheet.GetCells();

    // Setting text
    cells.Get(u"A1").PutValue(u"Hello!");

    // Setting number
    cells.Get(u"A2").PutValue(1000);

    // Setting Date Time
    Cell cell = cells.Get(u"A3");
    Date currentDate;
    currentDate.year = 2023; // Replace with actual current year
    currentDate.month = 10;  // Replace with actual current month
    currentDate.day = 5;     // Replace with actual current day
    currentDate.hour = 12;   // Replace with actual current hour
    currentDate.minute = 30; // Replace with actual current minute
    currentDate.second = 0;  // Replace with actual current second
    cell.PutValue(currentDate);

    // Setting style for date
    Style style = cell.GetStyle();
    style.SetNumber(14);
    cell.SetStyle(style);

    // Setting formula
    cells.Get(u"A4").SetFormula(u"=SUM(A1:A3)");

    // Saving the workbook to disk
    workbook1.Save(outputFilePath);

    std::cout << "Workbook saved successfully!" << std::endl;

    Aspose::Cells::Cleanup();
}
