FAQ

Does reversing columns also reverse the rows?

No. Row order stays the same; only column order changes.

Are formulas recalculated after columns move?

No. Formula text is preserved where available, but browser tools do not reproduce Excel's full calculation engine.

Can I reverse only one worksheet?

Yes. Choose the worksheet in the sheet selector.

Will blank columns inside the used range move too?

Yes. Columns inside the detected used range participate in the reversal.

Does the original file change?

No. A separate reversed workbook is created.
