How it works

Useful for API responses and app exports you need to read, filter or share with someone who lives in Excel. Header row is bold and frozen, filters are on, and number fields arrive as numbers.

Drop your JSON file above, check the preview, and click Convert & download. Excel is already selected, but you can pick any other format from the list.

Questions

Will nested fields get their own columns?

Yes. {"customer": {"email": "..."}} becomes a customer.email column.

What if records have different fields?

All fields found in any record become columns; records without a field leave that cell blank.

Is my data sent to a server?

No. The JSON is read and the workbook is built by your own browser.

Are my files uploaded anywhere?

No. The conversion happens in your own browser. There is no server receiving your data, no account and no daily limit.
