Request for adding JSON output support

[abhi-g80]

There already exists an PR #131 for this. Has been dormant for a while, hence requesting via a new issue. The original PR has the expected JSON out that I would expect. For brevity, pasting it here.

Not sure what the best way to get this feature added to the tool hence creating this issue. Can close this as duplicate if the original issue would be worked upon.
