Clean, parse, and check your syntax structures immediately in the browser.
JSON (JavaScript Object Notation) and XML (eXtensible Markup Language) are the two primary data formats used to transfer information between servers and clients. In their production environments, these files are often minified (whitespace, line breaks, and comments are removed) to conserve network bandwidth. A beautifier parses these structures and inserts correct indentation rules, restoring readability for debugging purposes.
This tool utilizes native browser APIs. For JSON parsing, it leverages the built-in JSON.parse() and JSON.stringify() engine. For XML, it employs the native DOMParser object to validate markup syntax, checking for open tags, attributes, and nesting rules. All calculations run strictly inside the browser sandbox, protecting sensitive configuration data.
Yes, absolutely. Our formatter operates 100% locally in your web browser using client-side JavaScript. No copy-pasted strings, configuration files, credentials, or API responses are sent to our servers or stored anywhere. Your sensitive code remains entirely on your local machine.
JSON (JavaScript Object Notation) is a lightweight, text-based data exchange format that uses key-value pairs and ordered lists, which maps natively to JavaScript objects. XML (eXtensible Markup Language) is a tag-based markup language that represents hierarchical data trees with attributes and namespaces, offering more complex schema validation capabilities but with higher data overhead.
When parsing JSON, the tool catches errors thrown by the browser's native JSON.parse engine and displays a helpful error message with the approximate line number. For XML, it uses DOMParser and checks the parsed document for parsererror tags, presenting the specific syntax issue to help you debug quickly.
