JSON to CSV converter

Turn a JSON array of objects into CSV rows you can open in a spreadsheet.

The input must be an array of flat objects. Cells that could run as spreadsheet formulas are prefixed with an apostrophe. JSON stays in this browser.

How to use

  1. Paste a JSON array of objects.
  2. Choose the delimiter.
  3. Convert, then copy or download the CSV.

What it supports

Accepts flat objects with string, number, boolean, or null values. Formula-like spreadsheet cells get an apostrophe prefix. Nested values are rejected. Input up to 100,000 characters.
