Convert JSON Arrays to CSV

The JSON to CSV converter turns a JSON array of objects into clean, comma-separated rows you can open in Excel, Google Sheets, or any data tool. It reads the keys from your objects to build the header row and maps each object to a line of values, handling quoting and escaping so that fields containing commas or quotes stay intact.

How it works

Conversion runs locally in your browser. Paste a JSON array and the tool inspects each object, collects the column names, and writes out CSV on your own device — no upload required. Because it is client-side JavaScript, even large arrays convert instantly and the tool keeps working offline.

How to use it

  • Export API data into a spreadsheet for analysis or reporting.
  • Hand a CSV to non-technical teammates who prefer Excel.
  • Prepare data for a bulk import into a CRM or database.
  • Turn logged JSON records into a tabular file.

Going the other direction is just as easy with CSV to JSON. For documentation, you can render the same data as a table using CSV to Markdown Table, and the JSON Formatter helps you inspect the source array first.

Private by design

Your JSON never leaves your browser, so customer records and other sensitive data stay on your machine. No account, no server, no tracking of what you paste.

Frequently asked questions

An array of objects, where each object becomes a row and its keys become the columns.
