Good to know

• JSON (JavaScript Object Notation) stores data as objects in curly braces with "key": value pairs, and lists in square brackets. Keys and text values must use double quotes.

Frequently asked questions

Is JSON Minify free?

Is my text saved?

Does it work on my phone?

Yes. It runs in any modern browser on a phone, tablet or computer - there is nothing to install.
