Access and Update the Portions of Rich Text of Cell with C++

Aspose.Cells allows you to access and update the portions of the rich text of a cell. For this purpose, you can use Cell.GetCharacters() and Cell.SetCharacters() methods. These methods will return and accept an array of FontSetting objects that you can use to access and update various font properties such as name, color, boldness, etc.

Access and Update the Portions of Rich Text of Cell

The following code demonstrates the usage of Cell.GetCharacters() and Cell.SetCharacters() methods using the source Excel file. The source Excel file contains rich text in cell A1 with three portions, each having a different font. The code accesses these portions and updates the first portion’s font to “Arial”. The modified workbook is saved as the output Excel file.

C++ code to access and update rich text portions

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

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

    U16String srcDir(u"..\\Data\\01_SourceDirectory\\");
    U16String outDir(u"..\\Data\\02_OutputDirectory\\");

    U16String inputPath = srcDir + u"Sample.xlsx";
    U16String outputPath = outDir + u"Output.out.xlsx";

    Workbook workbook(inputPath);

    Worksheet worksheet = workbook.GetWorksheets().Get(0);

    Cell cell = worksheet.GetCells().Get(U16String(u"A1"));

    std::cout << "Before updating the font settings...." << std::endl;

    Vector<FontSetting> fnts = cell.GetCharacters();

    for (int i = 0; i < fnts.GetLength(); ++i)
    {
        FontSetting& fs = fnts[i];
        std::cout << fs.GetFont().GetName().ToUtf8() << std::endl;
    }

    if (fnts.GetLength() > 0)
    {
        FontSetting& fs = fnts[0];
        fs.GetFont().SetName(u"Arial");
        cell.SetCharacters(fnts);
    }

    std::cout << std::endl << "After updating the font settings...." << std::endl;

    fnts = cell.GetCharacters();

    for (int i = 0; i < fnts.GetLength(); ++i)
    {
        FontSetting& fs = fnts[i];
        std::cout << fs.GetFont().GetName().ToUtf8() << std::endl;
    }

    workbook.Save(outputPath);

    Aspose::Cells::Cleanup();
    return 0;
}
