JSON returned by APIs is often compressed into a single line. Formatting adds indentation and line breaks without changing the underlying data.
How to format JSON online
Paste your JSON into the JSON Formatter, run the formatter and review the structured output. Objects and arrays become much easier to inspect.
Formatting vs validating JSON
Formatting improves readability; validation checks whether the syntax is valid. If your data produces an error, check it with the JSON Validator.
When should JSON be minified?
Readable formatting is useful during development. For compact storage or transfer, use the JSON Minifier to remove unnecessary whitespace.
