- Inspect nested keys and values in an easier-to-read layout.
JSON Formatter questions
What makes JSON invalid?
Common causes include missing quotes, single-quoted strings, trailing commas, mismatched braces, and unescaped control characters.
What is the difference between formatting and minifying JSON?
Formatting adds indentation and line breaks for people; minifying removes unnecessary whitespace to make the same data more compact.
