Notes on this conversion
Every sheet is kept: a six-sheet workbook was measured producing six sheets, which is why this is one of the four routes the multi-sheet CSV refusal recommends instead. The pair is published as deterministic and the conversion-loss table records no entry for it. Because ODS is a spreadsheet format rather than a flat table, calculated cells arrive as formulas rather than as frozen numbers — the difference from CSV, which has nowhere to put one — and the return trip, ODS to XLSX, is a supported route here too.

Frequently Asked Questions
Do all the sheets convert, or only the first?
All of them. A six-sheet workbook was measured producing six sheets, which is why this route is one of the four the multi-sheet CSV refusal recommends instead.
Do formulas stay formulas?
Yes. ODS is a spreadsheet format, so a calculated cell arrives as its formula rather than as a frozen number — the difference from CSV, which has nowhere to put one.
Can it go back to .xlsx later?
Yes — ODS to XLSX is a supported route here, so a workbook moved into the open format is not stranded there.
