Frequently Asked Questions

Why do SORT and FILTER show a #NAME? error in older Excel versions?

Older versions of Excel, such as Excel 2016 and 2019, do not support dynamic-array functions. If a workbook containing these functions is opened in an older version, Excel does not recognize the function name and returns a #NAME? error.

Can I get dynamic-array functions without subscribing to Microsoft 365?

Yes, you can purchase the perpetual license of Excel 2021 or newer standalone editions. These newer versions include native support for dynamic-array functions like SORT and FILTER without requiring a recurring monthly subscription.

Does the Office Quick Repair delete my personal files or settings?

No, running a Quick Repair from the Windows settings only checks and replaces corrupted installation files for Microsoft Office. It does not affect, modify, or delete your personal documents, spreadsheets, or customized application settings.
