Is there a way to validate JSON in Notepad++?

JSON Validator for Notepad++? was closed, and none of the links there point to an actual validator for JSON data.

I don't need to reformat JSON, I want a visual cue that I've missed a comma or a bracket.

How do I make Notepad++ do this, even if only like it would in XML if I did not close a string?

Thanks!

You can use Codverter JSON Validator, it`s online and highly secure, everything you do is interpreted on your local computer and never sent back to the server.
the validation error messages are informative and accurate.

(Full Disclosure: I am one of the developers).

The "Format JSON" option of the JSON Viewer will give an error if the JSON is not correct and also will select the incorrect text.

If the JSON is correct it will reformat but you can use undo (Ctrl+Z) to get it back to the previous format.
