What is the JSON to CSV Converter?

The JSON to CSV Converter turns JSON data into a spreadsheet-ready CSV file. Nested objects and arrays are flattened into their own columns (for example address.city or tags[0]), so the result opens cleanly in Excel or Google Sheets.

How to use this tool

  1. Paste your JSON into the left box, or click Load sample.
  2. Check the CSV that appears on the right, with the row and column count.
  3. Click Copy CSV or Download to save data.csv.
