Frequently asked questions
Are multiple worksheets converted?
Workbook conversion handles multiple sheets. Check sheet names and contents afterward, particularly when the workbook uses Excel-specific features.
Will macros, charts and formulas keep working?
Not always. Macros and specialized features are not retained; charts, some formulas and complex formatting may change. Verify calculations before relying on the file.
