How to use the JSON to CSV converter

  1. Paste a JSON array of objects, or switch to CSV to JSON.

  2. Sort by clicking a column header and filter the rows with the search field.

  3. Choose the separator and download or copy the CSV.

Frequently asked questions

What happens with nested objects?

Nested objects are flattened into columns with dotted names, such as address.city. Arrays inside a row are written as JSON text in one cell.

Which separator should I use for Excel?

Excel in most European languages expects a semicolon, in English a comma. Toolbox lets you choose, and the download opens directly in Excel with the right characters.
