dxSpreadSheetFeatureFunctionPrefix Constant

Specifies a string prepended to an XLSX name token of each registered spreadsheet function signature that corresponds to a function introduced in Microsoft Excel® 2010 and later.

Declaration

const dxSpreadSheetFeatureFunctionPrefix = '_xlfn.';

Remarks

XLSX import and export routines prepend this global constant value to the public names of certain registered function signatures to ensure compatibility with Microsoft Excel® 2010 and later.

The spreadsheet function signature’s GetPrefix function returns this global constant value instead of an empty string if the signature requires an XLSX name token prefix.
