Beautify, Validate, and Minify JSON data instantly in your browser.
JSON (JavaScript Object Notation) has become the de facto standard for data exchange on the web. It is lightweight, language-independent, and easy for machines to parse. However, raw JSON returned from APIs or stored in databases is often "minified"—meaning all unnecessary whitespace, newlines, and indentation have been removed to save space.
While minified JSON is great for computers, it is nearly impossible for humans to read or debug. A single line of code stretching for thousands of characters makes it difficult to understand the data structure or find errors.
This is where our JSON Formatter comes in. It takes that dense block of text and transforms it into a structured, indented, and readable format. This process, often called "beautifying" or "pretty-printing," allows developers to quickly scan the data hierarchy, verify keys and values, and troubleshoot integration issues.
Web developers frequently work with RESTful APIs or GraphQL endpoints. When an API returns an error or unexpected data, viewing the raw JSON response is the first step in debugging. By formatting this response, you can easily trace nested objects and arrays to pinpoint the exact location of the issue.
JSON is strict about syntax. A missing trailing comma, a single quote instead of a double quote, or an unclosed brace will cause parsers to fail. Our tool acts as a JSON Validator. Before you try to use the data in your application, you can paste it here to ensure it meets the standard JSON specifications. If it's invalid, the tool will tell you exactly why.
