A vendor stylesheet on one long line is a debugging wall. I have sat with devtools trying to match one broken rule inside a wall of text. Reformatting the file first turns that hunt into a search.
Paste minified or sloppy CSS and it comes back indented, one selector per rule, with readable declarations. The before and after is the whole trick: you rarely need more than formatting to spot the malformed line.
