About the Excel JSON Converter

With the Excel JSON tool, you can convert spreadsheet data into structured JSON directly in the browser.

Publish the output into other formats with CSV JSON and the table generator.

FAQ

Is XLS supported?

Yes. Both xlsx and xls files can be read, and you can select a sheet.

How are formula cells handled?

SheetJS typically returns the calculated value, so you may see the result rather than the formula text itself.

What about large sheets?

The preview may be limited to the first rows; check the full JSON output from the downloaded data if needed.
