About JSON
JSON (JavaScript Object Notation) is a lightweight data-interchange format, easy to read and write for humans and simple to parse and generate for machines. It's widely used in web APIs, configuration files and data storage.
JSON Syntax
Common Errors
Missing or extra comma between elements
Single quotes instead of double quotes
Unclosed braces or brackets
Comma after the last element (trailing comma)
Usage Tips
Use formatting to make JSON readable during development. Minify for production to reduce file size. Sorting keys alphabetically makes it easier to compare different versions of the same JSON.
