What is JSON?
JSON (JavaScript Object Notation) is a lightweight data interchange format that's easy for humans to read and write, and easy for machines to parse and generate.
How do I fix invalid JSON?
Common issues include trailing commas, single quotes instead of double quotes, unquoted property names, and JavaScript comments. Our Fix & Format feature automatically repairs these.
What's the difference between minify and beautify?
Beautify adds indentation and line breaks for readability. Minify removes all whitespace to reduce file size, useful for production deployments.
Smarter quality checks. Faster deployments.
Better apps.
