The CSV will appear here.

Overview

Converts JSON into CSV so you can open structured data in a spreadsheet. Useful for turning an API response or an export into rows and columns for Excel, Google Sheets, or a database import. It runs in your browser.

How it works

The tool takes an array of JSON objects and treats each object as a row. It uses the object keys as the column headers and lines up each object's values under them, producing comma-separated rows. The result is plain CSV text you can paste into or import as a spreadsheet. The conversion happens locally on your device.

How to use it

  1. Paste a JSON array of objects.
  2. The tool maps the keys to columns and each object to a row.
  3. Read or copy the CSV output.
  4. Open it in a spreadsheet or import it where you need it.

Examples

Records to a table

An array of objects with name and age keys becomes a header row of "name,age" followed by one row per object.

Prep for a spreadsheet

Convert an export so a non-technical teammate can open it in Excel.
