Normalized output

Running parsed JSON back through stringify helps smooth out inconsistent spacing and produce a stable pretty-printed result.

Useful after edits

It is handy when you want a clean canonical text version after manual changes or pasted content.

Validation built in

Invalid JSON never reaches the output because parsing happens before stringification.
