Frequently asked questions
How well does a WK1 worksheet convert to ODS?
The cell values, basic layout, and most formulas carry over into the OpenDocument Spreadsheet, which is a far richer format than CSV. Very old Lotus-specific features or formatting may not map perfectly onto the modern ODS model.
Why convert WK1 to ODS?
WK1 is an obsolete Lotus 1-2-3 binary format that current Excel cannot open, whereas ODS is an open, standardized spreadsheet format. Converting preserves the tabular structure in a format that stays editable.
Where does an ODS file open?
Natively in LibreOffice Calc and Apache OpenOffice, in Microsoft Excel (supported since 2009 with no add-in), and in Google Sheets. It is a vendor-neutral standard, so support is broad.
Does ODS keep more than CSV would?
Yes. Unlike CSV, ODS preserves multiple sheets, formulas, and cell formatting, so it is the better target when you want a working spreadsheet rather than just raw values.
