JSON to CSV Converter

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.

What makes a valid JSON input?

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.

Proper CSV escaping

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.
