What this does
- One line (LLM mode): converts all whitespace (newlines/tabs/multiple spaces) into single spaces and trims the ends.
- Collapse spaces/tabs: turns runs of spaces and tabs into a single space.
- Trim each line: removes leading and trailing whitespace per line.
- Remove empty lines: deletes blank lines (after trimming).
- Remove all line breaks: converts all line breaks into single spaces.
Tip: One-line mode is ideal for pasting into Claude/ChatGPT when you want fewer stray breaks and extra whitespace.
