FAQ
common questions
Why convert ODS to XLSX?
ODS (OpenDocument Spreadsheet) is the native format for LibreOffice Calc and OpenOffice; XLSX is Microsoft Excel's native format. In Microsoft-centric workflows (most corporate environments), XLSX is what colleagues, business systems, and standard tools expect. Converting makes ODS content drop-in compatible with the Microsoft Office ecosystem.
Will my formulas, formatting, and multiple sheets transfer?
Mostly yes. Both formats support formulas, formatting, multiple sheets, and named ranges — the converter maps between them. Most everyday spreadsheet content (calculations, cell formatting, charts, conditional formatting) round-trips cleanly. Format-specific extras (LibreOffice macros, very advanced ODF features) may not have direct XLSX equivalents.
Are there compatibility gotchas I should know about?
A few: LibreOffice's basic macros don't run in Excel (they're a different scripting language); some chart types render slightly differently between the two; complex pivot tables can lose configuration on round-trip; cell formatting at the edges (very specific number formats, exotic colour schemes) sometimes shifts. For complex workbooks, verify in Excel after conversion.
Will the XLSX be larger than the ODS?
Roughly similar. Both formats are ZIP-packaged XML internally; the XLSX-specific schema adds some overhead but compression usually levels out. Small spreadsheets are nearly identical in size; large workbooks with many sheets / formulas may differ by 10–20% in either direction.
Can I edit the XLSX in LibreOffice too after converting?
Yes — LibreOffice opens and edits XLSX natively (it's been a first-class format in LibreOffice for years). Converting ODS to XLSX doesn't lock you out of LibreOffice; you just gain compatibility with Excel-centric workflows. The XLSX is fully editable in both.
