Convert your Flat XML OpenDocument Spreadsheet (FODS) files into universally readable PDF documents instantly. This conversion is ideal for anyone needing to share spreadsheet reports without risking unauthorized edits.

FODS is an uncompressed XML-based spreadsheet format used by LibreOffice and OpenOffice, storing all table data in a single plain text XML file. When you convert FODS to PDF, the tabular layout, gridlines, and cell contents are rendered into a fixed-layout document. This freezes the exact visual presentation of your spreadsheet, making it ready for professional distribution.

The conversion from FODS to PDF happens without quality loss, preserving your exact table structures, fonts, and numbers. The output file size changes insignificantly compared to the original XML document.

Tips

Check your print area settings in LibreOffice before converting to ensure wide spreadsheets fit standard PDF page widths.
Verify that all gridlines are explicitly enabled in your FODS document if you want them visible in the resulting PDF.
Keep the original FODS file if you plan to update numerical data later, as PDF is a static document format.

Common use cases

Submitting financial spreadsheet reports to clients in a secure, non-editable format.
Archiving yearly accounting tables generated from open-source spreadsheet software.
Printing complex calculation sheets without worrying about shifting column widths across different devices.

Frequently asked questions

Yes, the calculated values resulting from your FODS formulas will appear correctly in the PDF, though the underlying formula logic will no longer be editable.

No, the conversion is performed without quality loss, keeping text crisp and vector table elements intact.
