How to convert 123 to CSV
- Add your .123 file - drop it in the box above or click to browse.

What to expect
- Formulas are not preserved - CSV exports only the calculated cell values, not the original Lotus @functions.
- CSV holds one sheet per file; a multi-sheet
.123workbook requires a separate export for each sheet. - Excel 2007 and later removed the Lotus import filter and will refuse to open
.123files - convert via LibreOffice first.
Frequently asked questions

How do I batch-convert many `.123` files?
The
ssconvert command-line tool (part of the Gnumeric package) can convert files in a script without opening a GUI each time.What data does `.123` store that CSV cannot hold?
Multiple sheets, formulas, cell formatting, named ranges, and charts - CSV carries only raw tabular values.
