How to convert between JSON and CSV formats

2 Click JSON → CSV to generate a comma-separated file from your data, or click CSV → JSON to parse tabular data into structured objects.

Moving data between JSON and CSV is one of the most common tasks for developers, analysts, and anyone working with APIs or spreadsheets. JSON is the standard format for web APIs and configuration, while CSV is the universal format for spreadsheets, databases, and data imports. This converter bridges the two formats instantly in your browser, so you can transform API responses into spreadsheet-ready files or turn exported CSV data into structured JSON for code or automation.

The tool automatically collects all unique keys from your JSON objects to build a complete CSV header, even when some objects have different fields. During CSV-to-JSON conversion, numeric values, booleans, and null are parsed into their proper types instead of staying as plain strings. That makes the output ready to use in code without additional cleanup. Quoted fields with commas, line breaks, and escaped quotes are handled correctly following standard CSV conventions.

Whether you are preparing seed data for a database, converting API output for a report, cleaning up exported analytics, or building test fixtures, a quick JSON-to-CSV round-trip saves time compared to writing custom scripts. The download button lets you save the CSV file immediately, which is useful when you need to share data with teammates who work in Excel or Google Sheets.
