Is my JSON sent to a server?

No. The editor runs entirely in your browser; your data stays on your device.

What is the difference from the JSON formatter?

The formatter pretty-prints or minifies text. The editor lets you change values in a tree or code view.

Yes. Tree mode expands objects and arrays so you can edit fields individually.

Invalid JSON shows an error when you load or export; fix syntax before copying.

Yes. Use the mode menu in the editor toolbar after loading valid JSON.

Very large documents may slow the browser, but nothing is uploaded to Frespy.
