Text copied from a PDF or a terminal often carries a line break after every visual line, not after every actual sentence or paragraph - which looks fine until you paste it somewhere that treats each of those breaks as a real new line. This flattens multi-line text into one continuous line, or keeps paragraph breaks intact and only flattens within each paragraph.

When you'd use this

Cleaning up text copied from a PDF, terminal output, or a poorly-formatted email before pasting it somewhere that should treat it as one continuous paragraph rather than dozens of short lines.

Common errors

If the result still has more breaks than expected, check whether "preserve paragraph breaks" is on - it only flattens within each paragraph (split on blank lines), not across the whole document. Turn it off to flatten everything into a single line.
