Move data between JSON and CSV
These tools convert JSON, JSON Lines and CSV so that data can move between APIs, scripts and spreadsheets. Nested objects can become dot-separated columns or stay as JSON text, and long numeric identifiers are kept as written instead of being rounded. You can paste data or choose a file, preview the output and download it. Processing stays in your browser, which helps when a file holds customer or internal records.
JSON to CSV
Convert JSON objects to CSV with nested-field options and preservation of long numeric values in the exported text.
