What is JSON?
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. It is widely used in web development and APIs for transmitting structured data.
✅ Why Use a JSON Formatter?
Poorly formatted JSON can be difficult to debug and maintain. A JSON formatter helps:
Beautify JSON with proper indentation.
Improve readability.
Detect structural errors
Make it easier to edit and share your JSON data
Our free JSON Formatter tool reformats raw or minified JSON into a clean, indented structure instantly.
Why Validate JSON?
Before using JSON in your app or sending it through an API, you should ensure it's valid. The JSON Validator:
Checks for syntax errors.
Confirms structure follows JSON standards.
Helps identify missing brackets, commas, or quotation marks
Our JSON Validator quickly confirms whether your JSON is correct and usable.
