What is JSON to CSV Conversion?

Converting JSON to CSV transforms structured data into tabular format readable by Excel, Google Sheets, and databases. Our converter handles arrays of objects, flattens nested structures, and lets you customize delimiters. Perfect for data analysis, reporting, and migrating between systems.

Frequently Asked Questions

What JSON structure works best?
Our converter works best with arrays of objects where each object has the same keys. Example: [{"id":1,"name":"A"},{"id":2,"name":"B"}]. Nested objects can be flattened.
How are nested objects handled?
Enable "Flatten nested objects" to convert {user:{name:"John"}} to columns like "user_name". Without flattening, nested values are JSON-stringified in the cell.
Can I convert JSON to Excel format?
CSV files open directly in Excel. After conversion, download the CSV and open it in Excel, or use Data > From Text/CSV import for more options.
