JSON Formatter & Validator
Paste your ugly JSON code below to format, beautify, and validate it instantly.
What is JSON Formatter & Validator?
JSON (JavaScript Object Notation) is a lightweight data-interchange format that is easy for humans to read and write, and easy for machines to parse and generate. However, when working with APIs or large datasets, JSON data often comes minified or unformatted, making it difficult to read and debug.
Our JSON Formatter & Validator tool helps developers instantly beautify their JSON strings into a structured, readable format with proper indentation. It also acts as a validator, instantly alerting you if there are syntax errors in your JSON code.
Features of our JSON Tool
- Beautify JSON: Automatically adds proper indentation and line breaks to make your JSON readable.
- Minify JSON: Removes all unnecessary whitespace, line breaks, and indentation to compress your JSON payload for faster transmission.
- Syntax Validation: Instantly validates your JSON structure and highlights if it is valid or invalid.
- Local Processing: Your JSON data is processed entirely in your browser. We do not send your sensitive API responses or data payloads to any external servers.
Common JSON Errors to Avoid
When working with JSON, ensure that all keys are enclosed in double quotes, avoid trailing commas after the last element in an array or object, and ensure proper nesting of curly braces `{}` and square brackets `[]`.
