What this tool does

JSON Formatter pretty-prints JSON (adds indentation and line breaks so it is readable) or minifies it (removes whitespace for compact size). It also validates — invalid JSON shows a clear error with the position of the problem.

Format or minify?

Format / Beautify — for reading or editing. Adds 2-space (or tab) indentation by convention.
Minify — for production. Strips all whitespace, reducing size by 20–40%.
