JSON to CSV Converter

What Is a JSON to CSV Converter?

Converting JSON to CSV is one of the most common data transformation tasks in web development, data analysis, and business intelligence. APIs return data as JSON, but spreadsheet applications (Excel, Google Sheets) and database import tools expect CSV. This converter handles the transformation client-side — your data never leaves your browser. It automatically extracts headers from JSON keys and handles quoting per RFC 4180.

Example

JSON Input:

[{"name":"Alice","age":30,"city":"NYC"},{"name":"Bob","age":25,"city":"LA"}]

CSV Output:

name,age,city
Alice,30,NYC
Bob,25,LA

How to Use This Converter

1. Paste your JSON data into the input panel.
2. View the converted CSV output — it updates instantly.
3. Click Copy to copy the result to your clipboard.
4. Verify the output matches your expectations before using in production.
