Is my data sent to a server?

No. All processing happens in your browser, so your JSON data is never transmitted externally.

Can it handle large JSON files?

It depends on your browser's memory, but it works fine for typical use cases. JSON files of several MB are generally not a problem.

What happens if I enter invalid JSON?

An error message is displayed and processing stops. Please check your input for issues and correct them.

Is indentation fixed at 2 spaces?

Currently formats with 2-space indentation.

What is the difference between Minify and Pretty Print?

Pretty Print adds indentation and line breaks for human readability. Minify removes unnecessary whitespace and newlines to reduce data size, which is useful for reducing API request payload sizes.
