How to use the JSON to Excel converter

  1. Choose a .json file or paste JSON — an array of objects works best (API responses, exports).
  2. Nested objects are flattened into columns like orders.total; lists become comma-separated text.
  3. Check the preview and download as Excel (.xlsx), CSV or OpenDocument.

Turn API data, database exports and app backups into a spreadsheet you can sort, filter and share with colleagues who do not read JSON. If the JSON is an object that contains an array (like {“data”:[…]}), the array is used automatically. Column widths are set to fit the content.
