Implement Cell.FormulaLocal similar to Excel VBA Range.FormulaLocal with C++

Possible Usage Scenarios

Microsoft Excel Formulas may have different names in different locales or regions or languages. For example, SUM function is called SUMME in German. Aspose.Cells cannot work with non-English function names. In Microsoft Excel VBA, there is Range.FormulaLocal property that returns the name of the function as per its language or region. Aspose.Cells also provides Cell.FormulaLocal property for this purpose. However, this property will only work when you will implement GlobalizationSettings.GetLocalFunctionName(string standardName) method.

Implement Cell.FormulaLocal similar to Excel VBA Range.FormulaLocal

The following sample code explains how to implement GlobalizationSettings.GetLocalFunctionName(string standardName) method. The method returns the local name of the standard function. If the standard function name is SUM, it returns UserFormulaLocal_SUM. You can change the code as per your needs and return the correct local function names e.g. SUM is SUMME in German and TEXT is ТЕКСТ in Russian. Please also see the console output of the sample code given below for a reference.

Sample Code

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

// Implement GlobalizationSettings class
class GS : public GlobalizationSettings
{
public:
    virtual U16String GetLocalFunctionName(const U16String& standardName) override
    {
        // Change the SUM function name as per your needs.
        if (standardName == u"SUM")
        {
            return u"UserFormulaLocal_SUM";
        }

        // Change the AVERAGE function name as per your needs.
        if (standardName == u"AVERAGE")
        {
            return u"UserFormulaLocal_AVERAGE";
        }

        return u"";
    }
};

void Implement_Cell_FormulaLocal_SimilarTo_Range_FormulaLocal()
{
    // Create workbook
    Workbook wb;

    // Assign GlobalizationSettings implementation class
    wb.GetSettings().SetGlobalizationSettings(new GS());

    // Access first worksheet
    Worksheet ws = wb.GetWorksheets().Get(0);

    // Access some cell
    Cell cell = ws.GetCells().Get(u"C4");

    // Assign SUM formula and print its FormulaLocal
    cell.SetFormula(u"SUM(A1:A2)");
    std::cout << "Formula Local: " << cell.GetFormulaLocal().ToUtf8() << std::endl;

    // Assign AVERAGE formula and print its FormulaLocal
    cell.SetFormula(u"=AVERAGE(B1:B2, B5)");
    std::cout << "Formula Local: " << cell.GetFormulaLocal().ToUtf8() << std::endl;
}

int main()
{
    Aspose::Cells::Startup();
    Implement_Cell_FormulaLocal_SimilarTo_Range_FormulaLocal();
    Aspose::Cells::Cleanup();
    return 0;
}

Console Output

Formula Local: =UserFormulaLocal_SUM(A1:A2)

Formula Local: =UserFormulaLocal_AVERAGE(B1:B2,B5)
