What changes
- Lotus 1-2-3 is opened by our office engine headless and exported as OpenDocument Spreadsheet, prioritizing office fidelity for lotus-to-ods.
- Cell values, visible formatting, charts, and sheet page setup influence export; formulas are evaluated from saved workbook state.
- Macros, scripts, document automation, and active form behaviour are not executed or preserved in the output.
- Missing fonts are substituted by server fonts, so line breaks and pagination can shift from the authoring machine.
- Tracked changes are accepted as the visible document state; reviewer comments may not appear unless they are visible in the exported view.
- The destination office file is editable but may not keep application-specific templates, themes, or unsupported controls exactly.
A real Lotus 1-2-3 → OpenDocument Spreadsheet run

- Range names are not carried over; formulas use plain cell references.
Options
