Frequently Asked Questions
What is JSON?
JSON (JavaScript Object Notation) is a lightweight data format used for storing and exchanging data between servers and web applications.
Why format JSON?
Formatted JSON is much easier to read and debug than minified JSON. Use formatting during development and minify for production.
What is minification?
Minification removes all unnecessary whitespace and line breaks, reducing file size for faster data transfer.
How do I validate JSON?
Just paste your JSON and click Format. If there are any syntax errors, they will be displayed below the input.
