JSON Minify and Beautify

This easy-to-use tool is designed to help you minify or beautify your JSON files, making it simpler to work with your data. If your JSON code is messy, unformatted, or difficult to read, this tool can transform it into a clean, organized structure that is easy to understand. Simply paste your JSON code into the box below and click either “Beautify JSON” to format it neatly, or “Minify JSON” to compress it into a compact, space-efficient version.

Properly formatted JSON makes it much easier to locate and extract the data you need, reduces errors, and improves readability, especially when working with large or complex datasets. JSON, which stands for JavaScript Object Notation, is a widely used data format for exchanging information between a browser and a server, allowing applications to communicate efficiently.

With this tool, you can quickly clean up your JSON code for development, debugging, or data processing, ensuring your data is well-structured, readable, and ready to use.

How to use it

The json minify and beautify web tool is a great tool to help you minify or beautify your json code.

Add your JSONPaste your JSON code into the editor above, or use Open file to load a .json file.
Beautify or minifyBeautify lays the code out on indented lines so it is easy to read and edit. Minify packs it into one line, which saves bandwidth and helps your website load faster. Ctrl+Enter also beautifies.
Check the resultThe editor shows the new code and the result box shows the size before and after. If the JSON has a mistake, the line is marked and your text is left as it was. Undo brings back the text from before.
Copy or downloadClick Copy to put the JSON on your clipboard, or Download to save it to your computer as a JSON file.

Good to know

Nothing is rounded

Numbers and text are written back exactly as they were, so a long ID such as 9781234567897123456 keeps every digit.

Your text is safe

If the JSON has an error, the tool tells you where it is and does not change what you typed. Fix it and try again.

Sort keys

Tick Sort keys A to Z to put the keys of every object in alphabetical order, which makes two files easier to compare.

Frequently asked questions

What is the difference between minify and beautify?

Beautify adds line breaks and indentation so people can read the JSON. Minify removes every space and line break that is not needed so the file is as small as possible. Both give you JSON that means exactly the same thing.

Why does it say my JSON is not valid?

The tool has to read your JSON before it can lay it out, so a mistake such as a missing comma, a trailing comma or a key without quotes stops it. The result box shows the line and column and marks the line in the editor. For a full check, try our JSON Validator.

Will it change my data?

No. Only the spacing between items changes. Numbers, text and the order of the keys stay as they were, unless you choose to sort the keys.

Can I use it for large files?

Yes. Use Open file to load a file of up to about 3 million characters, then beautify or minify it and use Download to save the result.

Is my JSON uploaded?

No. The formatting is done in your browser and nothing is sent anywhere.
