How to convert JSON to CSV
Paste a JSON array of objects and the tool flattens it into a CSV table, using the object keys as column headers. You can open the result directly in Excel, Google Sheets or Numbers. It's the fastest way to turn an API response or data export into a spreadsheet you can sort and filter.
When to convert JSON to CSV
JSON is ideal for code, but spreadsheets and non-technical colleagues need CSV. Converting lets you hand off data from an app or API to anyone who works in Excel, or import it into tools that only accept CSV. Everything is processed in your browser, so your data stays private on your device.
