Guide
A JSON to CSV Converter transforms JSON arrays into comma-separated values (CSV) format — the universal language of spreadsheets, databases, and data pipelines. If you've ever exported data from an API, a NoSQL database, or a JavaScript application and needed to open it in Excel, Google Sheets, or import it into a SQL table, you've hit this exact problem.
The UtilsGo JSON to CSV Converter runs entirely inside your browser. Your JSON data — which may contain customer records, financial transactions, or sensitive business data — never touches a server. Conversion is instant and the result can be downloaded directly as a .csv file or copied to your clipboard.
The converter expects a JSON array of objects, where every element shares the same top-level keys. Those keys become the CSV column headers, and each object becomes a row:
[
{ "name": "Alice", "role": "Engineer", "city": "Kathmandu" },
{ "name": "Bob", "role": "Designer", "city": "Pokhara" }
]
Single objects are also accepted (they produce a one-row CSV). Nested objects and arrays are stringified into their cell value — for deeply nested data you may want to flatten your JSON first using the JSON Formatter tool.
Values containing commas, double-quotes, or newlines are automatically wrapped in double-quotes and any internal quotes are doubled ("") per RFC 4180 — the CSV standard that Excel, Google Sheets, and most database import wizards follow.
Values with commas, quotes, or newlines are properly escaped so the CSV opens correctly in Excel, Google Sheets, and every standard import wizard.
Save the result directly to your computer as a .csv file with one click — no copy-paste into a text editor needed.
Your JSON data — which may include customer records, API keys, or financial data — never leaves your browser.
Accepts both JSON arrays and single JSON objects. Single objects are converted to a one-row CSV automatically.
Everything runs inside your web browser. We never upload your text, files, or personal data to any servers.
No sign-ups, no subscriptions, and no usage limits. Get your results instantly in a single click.
[{"a":1},{"a":2}]) or a single JSON object. Each top-level key becomes a column header. Nested objects/arrays are stringified as-is into their cell."Converted an API response with 500 records to CSV in under a second. Download button is a great touch — no fiddling with copy-paste."

"Needed to import MongoDB data into Google Sheets. This handled all the comma-in-value escaping correctly where other tools broke."
