A formula can be logically correct and still confuse a colleague using a different regional setup. Before sending an important workbook, check the elements most likely to vary.
Function language
Some spreadsheet installations display localized function names. Translate only from a known mapping rather than guessing.
Argument separators
Comma and semicolon differences are often tied to decimal settings. Keep quoted text untouched while converting separators.
Date assumptions
Prefer real dates and explicit DATE construction over ambiguous date strings.
External dependencies
Translation does not repair broken workbook links, missing add-ins, named ranges or macros. Test those separately.
