What is JSON to CSV Converter?

JSON to CSV Converter transforms JSON arrays of objects into properly formatted CSV files. It automatically detects column headers from JSON keys, handles nested objects by flattening them, and supports custom delimiters — perfect for importing 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 — Configure options: choose delimiter (comma, semicolon, tab), toggle header row inclusion, and select how to handle nested objects (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'.
