What to expect

  • Microsoft Excel 2007 and later dropped Lotus import filters entirely - Excel cannot open a .123 file directly.
  • Most formulas convert correctly, but obscure Lotus @functions may become static values; spot-check calculated totals after conversion.
  • Multiple sheets, column widths, and basic cell formatting are preserved; complex Lotus chart types may not render correctly.

Frequently asked questions

Can I convert 123 to ODS for free?
Yes. LibreOffice Calc and Gnumeric are both free and open-source - download LibreOffice from libreoffice.org, open the .123 file, and save as .ods.
Why can't I open a .123 file in Excel?
Microsoft removed Lotus 1-2-3 import support in Excel 2007. You must use LibreOffice or Gnumeric to open the file first, then save it to a format Excel understands.
Will my formulas survive the conversion?
Standard formulas and common Lotus @functions map across reliably, but unusual or outdated @functions may convert to static values - always verify key calculated cells.
Is there an online converter for .123 files?
The on-page converter above handles .123 files using LibreOffice on the server; most other online tools do not carry Lotus import support and will fail.
