JSON Tips

Common Errors

Missing quotes around keys, trailing commas, and single quotes instead of double quotes are common JSON mistakes.

Data Types

JSON supports strings, numbers, booleans, null, arrays, and objects. No undefined, functions, or dates.

Minification

Minifying JSON removes whitespace to reduce file size, useful for API responses and data transfer.

Formatting

Pretty-printing JSON with indentation makes it human-readable for debugging and configuration files.
