What to expect

  • Excel-specific VBA macros may not carry into the OpenDocument file and can require reworking.

Frequently asked questions

Does FODS keep my spreadsheet fully functional?
Yes, largely. FODS is the OpenDocument spreadsheet stored as a single flat XML file, so cells, formulas and most formatting carry over as a working spreadsheet.
Why convert an XLS to FODS?
FODS is an open, uncompressed XML form of an ODF spreadsheet, which is convenient when a plain-text, standards-based file is preferred over the proprietary binary XLS.
What is the difference from a normal ODS file?
FODS holds the same OpenDocument spreadsheet content but as one uncompressed XML document rather than a zipped package, which makes the file larger but human-readable as text.
What opens a FODS file?
FODS is an OpenDocument format opened by LibreOffice Calc and other suites that support ODF spreadsheets.
