FWIW, Right click -> Save As has served us reasonably well for quite a few years :)

Yes, you can save the page, but it makes scraping it harder if you want to have an automated tool do anything interesting with it. JSON, on the other hand, would be much simpler.

And we have plans to do so in the near future :)

Tested this in M-61, the "Export to JSON" button is not present on chrome://policy page.

M	Chrome OS	Chrome	        ARC	        Type	Channel
61	9765.76.0	61.0.3163.113	(multiple)	release	stable

However, this button is present in M-62, it allows to save policy to the policies.json file.

M	Chrome OS	Chrome    	ARC	Type	Channel
62	9901.37.0	62.0.3202.44	4372619	release	dev

Yes, that is normal, the change was landed in 62.

I changed the label accordingly.
