›What does the JSON formatter do?
It takes minified or poorly formatted JSON and adds proper indentation and line breaks to make it human-readable. It also validates the JSON and shows an error with exact line numbers if the input is invalid.
›What indent options are available?
You can choose 2 spaces, 4 spaces, or a tab character as the indentation style.
›What is JSON minify?
Minify removes all whitespace from the JSON, making it as compact as possible. This is useful before sending JSON in API requests or storing it in a database.
›Is my JSON sent to a server?
No. All formatting and validation happens in your browser using the built-in JSON.parse and JSON.stringify functions. Nothing is uploaded.
