Frequently Asked Questions

Which applications create ODS files?

LibreOffice Calc, Apache OpenOffice Calc, Google Sheets (export), Collabora Online, GNOME Gnumeric, and many other open-source spreadsheet tools create ODS files.

Which sheet is converted?

The first sheet in the ODS workbook is converted. If you need a different sheet, rearrange sheets in your spreadsheet app before converting.

Are formulas preserved?

Formulas are resolved to their last computed values. The CSV output contains calculated results, not formula expressions.

How are dates handled?

ODS dates are converted to their formatted text representation. The output format depends on how dates were formatted in the original spreadsheet.

What about merged cells?

Merged cells are unmerged. The value appears in the top-left cell of the merge range, and other cells become empty.

Do I need LibreOffice installed?

No. The converter parses ODS files directly in your browser using SheetJS. No office suite is required.

Are charts and images preserved?

No. Charts, images, and visual elements are stripped. Only cell data and values are included in the CSV output.

What encoding does the CSV output use?

The output uses UTF-8 encoding, supporting all international characters and symbols.

How large of an ODS file can I convert?

The converter handles moderately sized ODS files well. Performance depends on your device's memory.

Is my data secure?

Yes. The conversion happens entirely in your browser. Your spreadsheet data is never uploaded to any server.
