When You Need JSON Converted to CSV

Your API returns JSON, but your boss wants an Excel report. The PM needs Google Sheets to track progress. A client needs CSV to import into their system. This tool takes a JSON array and turns it into a CSV file — no scripting, no Python, no command-line gymnastics.

What Kind of JSON Works Best?

The ideal input is an array of flat objects — something like [{"name":"Alice","age":30}, {"name":"Bob","age":25}]. Each object's keys become column headers, and the values become row data. If your JSON has nested objects (objects inside objects), those fields will show up as [object Object] in the CSV, so you'll want to flatten the data first.

Common Use Cases

Backend devs pulling database records for non-technical teammates. Data analysts piping API responses into Excel for pivot tables. PMs exporting user data as CSV for the marketing team's mailing list. And the classic scenario: migrating between systems where the old platform exports JSON and the new one only accepts CSV.

A Few Things to Know

If your data contains commas or line breaks, the converter wraps those fields in double quotes automatically — so the CSV format stays intact. If Excel shows garbled characters when you open the file, it's usually an encoding issue — try saving as UTF-8 with BOM. This tool runs entirely in your browser, so your data never hits a server. Safe for internal company data, customer records, or anything you'd rather keep private.
