JSON Formatter
Use this JSON formatter to pretty-print raw JSON with indentation. It runs in the browser and makes nested objects and arrays much easier to inspect.
Example Usage
- Paste minified JSON from an API response and turn it into readable structured output.
- Format nested objects and arrays before comparing payloads manually.
- Use the result when debugging API responses, config files, or JSON-based data flows.
JSON Formatter Explained
A JSON formatter takes raw JSON and rewrites it with line breaks and indentation so the structure becomes easier to read. This is useful when you are inspecting API responses, editing configuration files, or debugging payloads that arrive in minified form. Large JSON strings are difficult to reason about when everything appears on one line, especially with nested arrays and objects. This tool parses the input and returns a neatly formatted version instantly in the browser. That makes it a fast way to inspect data without opening a terminal or relying on external tooling.
FAQ
Does this JSON formatter validate the input too?
Yes. If the JSON is invalid, the tool will show an error instead of formatted output.
Can it handle nested arrays and objects?
Yes. Valid JSON structures are reformatted with standard indentation regardless of depth.
Does the tool send my JSON anywhere?
No. Formatting happens in the browser with no backend dependency.
