Avoid exponential notation of large numbers while importing from HTML with C++

Sometimes your HTML contains numbers like 1234567890123456 which are longer than 15 digits, and when you import your HTML to an Excel file, these numbers are converted to exponential notation like 1.23457E+15. If you want your number to be imported as it is and not converted to exponential notation, then please use the HTMLLoadOptions.GetKeepPrecision() property and set it to true while loading your HTML.

The following sample code explains the usage of the HTMLLoadOptions.GetKeepPrecision() property. The API will import the number as it is without converting it to exponential notation.

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

using namespace Aspose::Cells;

int main()
{
    Startup();

    U16String html = u"<html><body><p>1234567890123456</p></body></html>";

    std::vector<uint8_t> byteArray;
    for (int32_t i = 0; i < html.GetLength(); ++i)
    {
        char16_t c = html[i];
        if (c <= 0x7F)
            byteArray.push_back(static_cast<uint8_t>(c));
    }

    HtmlLoadOptions loadOptions = HtmlLoadOptions(LoadFormat::Html);
    loadOptions.SetKeepPrecision(true);

    Vector<uint8_t> data(byteArray.data(), static_cast<int32_t>(byteArray.size()));
    Workbook workbook(data, loadOptions);

    Worksheet sheet = workbook.GetWorksheets().Get(0);
    sheet.AutoFitColumns();

    U16String outDir(u"..\\Data\\02_OutputDirectory\\");
    workbook.Save(outDir + u"outputAvoidExponentialNotationWhileImportingFromHtml.xlsx", SaveFormat::Xlsx);

    std::cout << "File saved successfully." << std::endl;

    Cleanup();
    return 0;
}
