Frequently Asked Questions
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 based on a subset of JavaScript and uses key-value pairs and ordered lists.
Why should I format JSON?
Formatted JSON with proper indentation is much easier to read, debug, and share with team members. Minified JSON saves bandwidth when transmitted over networks. This tool lets you switch between both formats instantly.
How do I validate JSON?
Click the Validate button. The tool will attempt to parse your JSON using the built-in JavaScript parser. If there is a syntax error, it will display the exact error message and approximate position so you can fix it quickly.
