Clean up messy line-based text in one pass

Paste a list, a log, or copied text and apply several line operations at once. Remove blank lines drops empty and whitespace-only rows; Trim strips leading and trailing spaces; Remove duplicates keeps the first occurrence of each line; and Sort orders the result A→Z or Z→A. Combine them — the live count shows how many lines remain.

Whole vs adjacent duplicates

Whole-list dedupe removes every repeat anywhere; “Adjacent only” removes a line only when it equals the line directly above it — useful for collapsing runs without reordering. Turn on “Ignore case” to treat Apple and apple as the same.

FAQ

Does it handle Windows line endings?

Yes. CRLF, CR, and LF are all recognized; output is normalized to LF newlines.

What order are the operations applied?

Trim first, then blank-line removal, then dedupe, then sort, then optional numbering — so a trailing space never blocks a duplicate from being detected.
