About This Free Online JSON to CSV Converter
Our free JSON ⇄ CSV Converter moves data between the two most common formats. Paste an array of JSON objects and it produces a clean, spreadsheet-ready CSV with a header row built from the keys; paste CSV and it parses it back into a JSON array of objects. It handles quoted fields, commas inside values, and uneven keys, so you can move data between APIs, databases, and spreadsheets like Excel or Google Sheets without writing a script. Everything runs in your browser, so your data is never uploaded — no signup and nothing leaves your device.

Frequently Asked Questions About JSON to CSV Converter
What JSON format does it expect for CSV output?
An array of objects, like [{"name":"Ann","age":30}, …]. Each object becomes a row and the keys become the column headers. Uneven keys across objects are handled — missing values are left blank.
Does it handle commas and quotes inside values?
Yes. Values containing commas, quotes, or line breaks are properly quoted and escaped in CSV, and parsed back correctly from CSV to JSON.
Can I open the CSV in Excel or Google Sheets?
Yes — the CSV uses a standard header row and comma delimiter, so it opens directly in Excel, Google Sheets, Numbers, and any spreadsheet app.
Is my data uploaded?
No. The conversion runs entirely in your browser. Nothing is sent to a server and there is no signup.
Why Choose the JSON to CSV Converter?
Developers and power users need tools that are exact and private. The JSON to CSV Converter runs its logic locally in your browser, returns results instantly, and never transmits your input — handy when you are working with keys, hashes, or data you would rather not paste into a remote service.
