Reading CSV File with Multiple Encodings with C++

Sometimes, your CSV file contains multiple encodings (Unicode, ANSI, UTF8, UTF7, etc). Aspose.Cells allows you to load such CSV files and convert them into other formats, for example, PDF or XLSX.

Aspose.Cells provides the TxtLoadOptions.IsMultiEncoded property, which you need to set to true to load your CSV file with multiple encodings properly.

The following screenshot shows a sample CSV file that contains two lines. The first line is in ANSI encoding and the second line is in Unicode encoding.

Input file

The following screenshot shows the XLSX file converted from the above CSV file without setting the TxtLoadOptions.IsMultiEncoded property to true. As you can see, the Unicode text was not converted properly.

Output file 1: no accommodation made for multiple encoding

The following screenshot shows the XLSX file converted from the above CSV file after setting the TxtLoadOptions.IsMultiEncoded property to true. As you can see, the Unicode text is now converted properly.

Output file 2: IsMultiEncoded is set to true

Below is the sample code that converts the above CSV file into XLSX format properly.

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

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

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

    // Path of input CSV file
    U16String filePath = srcDir + u"MultiEncoded.csv";

    // Create TxtLoadOptions and set MultiEncoded property to true
    TxtLoadOptions options;
    options.SetIsMultiEncoded(true);

    // Load the CSV file into Workbook with the specified options
    Workbook workbook(filePath, options);

    // Save the workbook in XLSX format
    workbook.Save(filePath + u".out.xlsx", SaveFormat::Xlsx);

    std::cout << "File converted successfully!" << std::endl;

    Aspose::Cells::Cleanup();
}
