Frequently Asked Questions

UDF functions work with Excel versions that support add-ins. Compatibility may vary with very old Excel versions.

Yes, but all users need the Unleashed Flow add-in installed to see function results correctly.

UDF functions require the desktop add-in and may not work in web or mobile versions of Excel.

The library contains pre-built functions. Custom function development would require VBA programming skills.

Functions will show #NAME? errors if the add-in is removed. Keep the add-in installed to maintain functionality.
