JSON to CSV

Turn API JSON into spreadsheet-ready CSV. Arrays of objects become rows; nested objects flatten to dot-separated column names so Excel and Google Sheets can open the file.

Result

Paste JSON, then Convert. Nested fields flatten to columns.

How to convert JSON to CSV

  1. Paste JSON — an array of objects works best; a single object becomes one row.
  2. Click Convert.
  3. Nested fields flatten to dot-separated column names (for example address.city).
  4. Copy the CSV or download the file for Excel or Google Sheets.
