About the JSON to CSV Converter
Need to turn a JSON file into CSV? This free converter changes JSON data files into CSV in a few seconds, right in your browser. People usually convert because JSON is hard for non-developers to read and does not open in Excel, while CSV gives you a CSV ready to import anywhere. CSV files open in Excel, Google Sheets, Notepad, MySQL, pandas and every CRM.
The file is parsed with well-tested open-source parsers (the browser's JSON and XML parsers, js-yaml and smol-toml) and written back out as valid CSV. Because everything happens on your own device, your data files are never uploaded, stored or seen by anyone else, which makes it safe for customer lists, salary sheets, GST data and API exports.
What to expect: nested objects are flattened into columns such as address.city, and the first list of records found in the file becomes the rows; invalid input is reported with the line of the problem so you can fix it.
How to use the JSON to CSV Converter
- Click "Choose files" or drag your JSON data files onto the box. You can add several at once.
- No settings are needed; indentation and types are handled automatically.
- Press "Convert to CSV". The conversion runs on your device and shows its progress.
- Download each CSV file, or use "Download all (ZIP)" when you converted several.
- Open the result in Excel or Google Sheets to check it; your original JSON is never changed.
Tips & benchmarks
- CSV holds one table without formatting; with several sheets you get one CSV per sheet, bundled in a ZIP.
- Lists of simple values are joined with semicolons, and lists of objects are kept as JSON text in one cell, so no information is lost.
- Keep the file name simple (letters, numbers and hyphens) if you plan to upload the CSV to a website or government portal.
Frequently asked questions
How do I convert JSON to CSV?
Click "Choose files", select your JSON data files, adjust the options if you want, and press "Convert to CSV". The CSV downloads immediately; with several files you can download everything as one ZIP.
Is this JSON to CSV converter free and safe?
Yes. It is completely free, with no sign-up, no daily limit and no watermark. The conversion runs inside your browser, so your data files never leave your phone or computer and nothing is stored on News Appite's servers.
What happens to nested data?
Tables are flat, so nested objects become dotted column names (for example user.address.city). Lists of simple values are joined with semicolons and lists of objects are stored as JSON text in one cell.
Can I convert several JSON files at once?
Yes. Add as many JSON files as you like; they are converted one after another and you can download them individually or together as a ZIP.
Does it work on iPhone, Android and Mac?
Yes. The converter works in any modern browser, including Chrome, Safari, Edge and Firefox, on Android, iPhone, iPad, Windows, macOS and Linux. No app is needed.
What is the difference between JSON and CSV?
JSON (JavaScript Object Notation) is a structured data (text) best suited to APIs, web and mobile apps, configuration and MongoDB or Firebase data. CSV (Comma-Separated Values) is a plain-text table best suited to importing data into databases, CRMs, Tally, mailing tools and Python or R.
Is there a file size limit?
There is no upload limit, because nothing is uploaded. The practical limit is your device's memory: files of a few hundred megabytes work on most computers, and phones handle smaller files comfortably.
How do I convert JSON to CSV in Excel?
In Excel 2016 or Microsoft 365 use Data → Get Data → From File → From JSON, expand the records in Power Query and click Load; then save the sheet in the format you need. This converter does the same in one click, with nested fields flattened automatically.
How do I convert JSON to CSV in Python?
With pandas: df = pd.json_normalize(json.load(open('input.json'))), then df.to_csv('output.csv', index=False). If you just need the file, this converter does it in the browser without writing any code.

What is a JSON file?
JSON is the data format of the modern web: almost every API, app configuration and NoSQL database speaks it. It represents objects, arrays, numbers and text in a compact, human-readable way.
What is a CSV file?
CSV stores a single table as plain text, one row per line with values separated by commas. Every spreadsheet, database, CRM and programming language can import it, which makes it the universal format for moving data.
