FAQ
What is JSON formatting?
JSON formatting (pretty-printing) adds indentation and line breaks to make JSON data human-readable. It does not change the data itself.
How to validate JSON?
Click the Format button — if your JSON is invalid, an error message will appear. Valid JSON must have quoted keys, correct brackets, and no trailing commas.
What is minified JSON?
Minified JSON removes all whitespace to reduce file size, which is useful for sending data over a network where bandwidth matters.
