JSON formatting for API debugging

JSON formatting and validation turns minified or messy JSON into a readable structure for API debugging, configuration review, log inspection, and frontend-backend collaboration.

Parsing runs in the browser. When formatting fails, the cause is often invalid quotes, commas, braces, escaping, or comments that are not valid JSON.

FAQ

Can JSON contain comments?expand_more

Standard JSON does not support comments. Commented files are usually JSONC or another extended format.

Is my data uploaded to a server?expand_more

The page primarily processes the input in the browser, which is suitable for general API data and config snippets.

What is the difference between format and minify?expand_more

Formatting adds line breaks and indentation for reading; minifying removes extra whitespace for transfer or storage.
