Question 1

What can the JSON Formatter do besides pretty-printing?

Accepted Answer

It validates, minifies, sorts keys alphabetically, escapes JSON as a string and unescapes string-wrapped JSON, all with clear line-numbered error messages.

Question 2

Is my JSON uploaded?

Accepted Answer

No. All parsing and formatting happens in your browser — your data never leaves your device.

Question 3

Is it free?

Accepted Answer

Yes, completely free with no ads and no sign-up.
