Question 1

What is JSON?

Accepted Answer

JSON (JavaScript Object Notation) is a lightweight text format for storing and transporting data. It is human-readable and widely used in APIs, configuration files, and data exchange between systems.

Question 2

What is the difference between JSON formatting and minifying?

Accepted Answer

Formatting (beautifying) adds indentation and line breaks to make JSON readable for humans. Minifying removes all whitespace to produce the smallest possible output, which is faster to transmit over a network.

Question 3

Is my JSON data sent to a server?

Accepted Answer

No. All formatting, validation, and parsing happens entirely in your browser using JavaScript. Your JSON data never leaves your device.

Question 4

Why is my JSON invalid?

Accepted Answer

Common JSON errors include: trailing commas after the last item in an object or array, single quotes instead of double quotes around strings, unquoted property keys, and comments (JSON does not support comments). The error message shows the position of the first problem.
