Question 1

What is JSON?

Accepted Answer

JSON (JavaScript Object Notation) is a lightweight data format used for storing and transmitting data. It's human-readable and easy for machines to parse, making it the most popular format for web APIs.

Question 2

What's the difference between format and minify?

Accepted Answer

Formatting (beautifying) adds indentation and line breaks for readability. Minifying removes all whitespace to minimize file size — useful for production environments.

Question 3

How does JSON validation work?

Accepted Answer

Validation checks your JSON in real-time as you type. If there's an error, it shows the error message and the approximate line number where the issue occurs.

Question 4

Is my data sent to any server?

Accepted Answer

No, all processing happens in your browser. Your JSON data is never transmitted to any server, so you can safely use it with sensitive data.

Question 5

Can it handle large JSON files?

Accepted Answer

Yes, processing happens in browser memory so typical JSON files work fine. Very large files (tens of MB) may slow down depending on browser performance.
