The Best Free JSON to CSV Converter
JSON is the standard data format for APIs and web services, but spreadsheet apps like Excel and Google Sheets use CSV (Comma-Separated Values). The GadgetsFocus free online JSON to CSV Converter bridges this gap by transforming your JSON array of objects into a clean CSV file you can open in any spreadsheet application.
How to Use
- Paste JSON: Copy your JSON array into the left text area. It should be an array of objects (e.g., from an API response).
- Convert: Click “Convert to CSV” to generate the CSV output on the right.
- Download: Click “Download .csv” to save the file to your computer and open it in Excel, Google Sheets, or Numbers.
What Makes This Tool Special
- Auto-detects Headers: The tool scans all objects in your array and collects every unique key to build the complete set of CSV column headers.
- Handles Edge Cases: Values containing commas, quotes, and newlines are properly escaped per the CSV specification (RFC 4180).
- No Server Upload: Your data is processed entirely in your browser. Sensitive API data is never transmitted anywhere.
