What is JSON to CSV Converter?

JSON to CSV Converter turns JSON arrays of objects into CSV files. It reads column headers from JSON keys, flattens nested objects, and lets you pick a custom delimiter. Great for getting data into spreadsheets or databases.

How to use

1. Step 1 — Paste a JSON array of objects (e.g., [{"name": "Alice", "age": 30}, ...]) or upload a .json file.
2. Step 2 — Pick a delimiter (comma, semicolon, or tab), decide whether to include a header row, and choose how nested objects are handled (flatten with dot notation or stringify).
3. Step 3 — Preview the CSV output in a table view, then download the .csv file or copy it to clipboard.

Result

You export 500 user records from an API as JSON. Paste the array, choose comma delimiter with flattened nested objects, and download a clean CSV ready to open in Excel with columns like 'address.city' and 'address.zip'.
