Frequently Asked Questions (FAQ):

Q: What is the difference between beautifying and minifying JSON?
A: Beautifying adds proper indentation, line breaks, and structure to make JSON readable and maintainable. Minifying removes all unnecessary characters (spaces, line breaks) to reduce file size for faster data transfer in production environments.

Q: Is there a file size limit for this JSON beautifier?
A: You can beautify very large JSON files, including complex API responses and database exports, without any issue. The tool is built to handle megabytes of JSON data at once.

Q: Is my JSON data kept private and secure when I use this tool?
A: Absolutely. This is a core principle of our tool. The beautification happens locally on your own computer or phone. Your JSON data is never sent to any server, meaning we never see, store, or have access to your data. It is 100% secure.
