How to Use the JSON to CSV Converter
Paste a JSON array of objects and click Convert to get a spreadsheet-ready CSV. Each object in the array becomes one row; the keys become column headers. Values containing commas or line breaks are automatically quoted to ensure correct parsing. The downloaded file includes a UTF-8 BOM so Excel opens it correctly without encoding issues. All processing happens in your browser — your data is never sent to a server.
