Why it is different
- No macros, no add-ins. Opens in Excel 2010+, Google Sheets and LibreOffice.
- Every number is double-checked: all files were recalculated and compared with independent calculations.
- Works with any currency.
- Sample files included so you see it working before you type anything.
Honest note
Verified in LibreOffice. I have not opened the files in Microsoft Excel or Google Sheets themselves; tell me if anything looks off.
