Pixuna

JSON to CSV

Convert a JSON array into CSV, flattening nested objects.

Everything is processed inside this browser tab. Pixuna does not upload your text or files to a server.

How to use JSON to CSV

  1. Paste JSON or open a .json file.
  2. Pick the output delimiter.
  3. Copy or download the CSV.

What to know

Nested objects become dotted column names such as address.city.

Arrays of simple values are joined with "; ". Arrays of objects are stored as JSON text in one cell.

File handling: This tool runs in your browser. Your text or file is processed in the tab on your device, and Pixuna's code does not upload it to a server. You can confirm this in your browser's network panel.
