ODS to JSON Converter

Convert ODS files to JSON. Free and without uploading.

This tool converts ODS files to JSON. ODS is LibreOffice Calc’s open spreadsheet format.

JSON is the text format programs use to exchange data. All sheets, numbers and dates are carried over. Some formatting, such as cell colours, may be lost in the target format.

Conversion happens inside your browser; your files are never sent to a server.

How to use

1. Drag and drop your ODS files, paste them, fetch one from a link, or use "Choose files".
2. The target format is preselected; you can add several files at once.
3. Press "Convert" and download the JSON files.

Frequently asked questions

Is anything lost when converting ODS to JSON?

The content is kept; formatting the target format doesn’t support (such as colours or fonts) may be lost.

How many files can I convert at once?

There is no limit. Download the results one by one or as a ZIP.

Are my files uploaded?

No. Your ODS files are converted to JSON inside your browser.
