JSON to CSV Converter.

How to convert JSON into CSV

1. Paste a valid JSON array. Each element must be an object, such as {"name":"Asha","age":25}.
2. Click Convert to CSV to create a header row from the available keys, including keys that appear only in later records.
3. Review the preview, then copy the CSV or download it as a UTF-8 file for Excel, Google Sheets or another spreadsheet program.

Nested object example

The object {"name":"Asha","location":{"city":"Jaipur"}} becomes two columns: name and location.city. Missing values in other records become empty CSV cells.

What this converter handles

Commas and quotation marks: CSV values containing commas, double quotes or line breaks are quoted and escaped, so names and notes survive export.

Spreadsheet formula protection: Strings beginning with =, +, - or @, including leading whitespace, receive a protective apostrophe. This is a mitigation, not a guarantee across every spreadsheet importer.

Nulls, arrays and nested data: Null and missing fields are blank; nested objects become dotted keys; arrays are stored as JSON text in one cell.

Limits: Duplicate JSON keys may be overwritten by the browser's JSON parser. Ambiguous flattened keys are rejected. The tool is not a JSON schema validator, and does not convert an arbitrary JSON object or nested arrays of records automatically.
