E.g. a command-line tool, a Notepad++ Plugin or something similar?
(My imagined usage would be something like:
$> beautify ugly.json >> beautiful.json )
Got it, the solution is jq! ( https://stedolan.github.io/jq/ )

$> jq . ugly.json >> beautiful.json
Found it by following #json and thus discovering https://mastodon.social/@YesIKnowIT/101167193159044425 !
