How to convert JSON to CSV
Converting JSON to CSV takes three quick steps:
- Add one or more JSON files — drag and drop them or click to browse.
- Click Convert to CSV and let the conversion run in your browser.
- Download your new CSV files individually or as a batch.
What is JSON?
JSON is the standard data format for web APIs and modern applications. It represents structured data with objects, arrays, strings and numbers in a lightweight, human-readable text format that every programming language can parse.
What is CSV?
CSV is the simplest way to store tabular data: each line is a row and commas separate the columns. It is plain text, opens in Excel, Google Sheets and any programming language, and is the universal format for exporting and importing spreadsheets and databases.

Why convert JSON to CSV?
Converting JSON to CSV gives you a file that is better suited to spreadsheet exports and imports and moving data between apps, and that opens it up to far more apps, devices and websites.
What CSV gives you: opens in every spreadsheet and language, tiny and human-readable and easy to generate.
Where JSON falls short: more verbose than CSV for flat tables, no comments in standard JSON and strict syntax — one typo breaks it. Converting keeps your content while moving to a format that matches where the file is going.
Tips for the best results
- CSV is lossless, so your converted files keep every detail of the original JSON.
- You can convert several files in one go — add as many JSON files as you like and download them together.
- Everything runs locally in your browser, so even large files convert quickly and nothing is uploaded.
