Replace text in a workbook using Regular Expression with C++

Aspose.Cells provides the feature to replace text in a workbook using a regular expression. For this, the API provides the GetRegexKey() property of the ReplaceOptions class. Setting the GetRegexKey() to true indicates that the searched key will be a regular expression.

The following code snippet demonstrates the use of the GetRegexKey() property by using the sample excel file. The output file generated by the following code snippet is attached for reference.

Sample Code

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

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

    // For complete examples and data files, please go to https://github.com/aspose-cells/Aspose.Cells-for-C

    // Source directory path
    U16String sourceDir = u"..\\Data\\01_SourceDirectory\\";
    
    // Output directory path
    U16String outputDir = u"..\\Data\\02_OutputDirectory\\";

    // Create workbook from the input file
    Workbook workbook(sourceDir + u"SampleRegexReplace.xlsx");

    // Create replace options
    ReplaceOptions replace;
    replace.SetCaseSensitive(false);
    replace.SetMatchEntireCellContents(false);
    // Set to true to indicate that the searched key is regex
    replace.SetRegexKey(true);

    // Perform the regex replace operation
    workbook.Replace(u"\\bKIM\\b", u"^^^TIM^^^", replace);

    // Save the modified workbook
    workbook.Save(outputDir + u"RegexReplace_out.xlsx");

    std::cout << "Regex replace operation completed successfully!" << std::endl;

    Aspose::Cells::Cleanup();
