Frequently Asked Questions

What is JSON?

JSON (JavaScript Object Notation) is a lightweight data format for storing and transmitting structured data. It uses key-value pairs and arrays, and is the most common format for APIs and configuration files.

Why does my JSON fail to parse?

Common JSON errors: trailing commas (not allowed), single quotes instead of double quotes, unquoted keys, missing commas between elements, or special characters not properly escaped.

What is the difference between formatting and minifying?

Formatting (beautifying) adds proper indentation and line breaks to make JSON human-readable. Minifying removes all whitespace and line breaks to make JSON compact for transmission or storage.
