Convert JSON to CSV Online

Exporting JSON Data to CSV

When you need to move data from an API, database export, or JSON file into a spreadsheet (Excel, Google Sheets) or import into another database, CSV is the universal interchange format. Our converter takes a JSON array of objects and produces clean CSV with headers derived from the object keys.

The converter handles nested objects by flattening them with dot notation — {"user": {"name": "Alice"}} becomes a user.name column. Arrays within objects are joined with commas. Fields containing commas, quotes, or newlines are automatically escaped per RFC 4180.

This is commonly needed for analytics exports (converting API data for reporting), data migration (moving between systems), and ad-hoc analysis (when you want to filter and sort JSON data in a spreadsheet instead of writing code).

Tips

• Your JSON must be an array of objects: [{"name": "Alice"}, {"name": "Bob"}].
• Nested objects are flattened with dot notation — address.city becomes a column header.
• The first object determines the column order. If later objects have additional keys, they're added as new columns.
• Open the downloaded CSV in Google Sheets or Excel for filtering, sorting, and charting.
