Frequently Asked Questions
What is JSON?
JSON (JavaScript Object Notation) is a lightweight data interchange format. It is easy for humans to read and write, and easy for machines to parse and generate. JSON is built on two structures: a collection of name/value pairs (objects) and an ordered list of values (arrays).
Is my data safe when using this tool?
Yes. All processing happens entirely in your browser using JavaScript's JSON.parse and JSON.stringify. Your data never leaves your device - no uploads, no servers, no storage.
What is the difference between Format and Minify?
Format/Beautify adds indentation and line breaks to make JSON readable. Minify removes all whitespace to make JSON as compact as possible - useful for reducing file size in production APIs.
Can I validate JSON with this tool?
Yes! Every time you format or minify, the tool validates your JSON. If it is invalid, a red error message will show exactly where the problem is. Valid JSON turns green.
