Frequently asked questions
What is Count Lines used for?
Use it to see how many rows a paste contains, including a quick check before you sort or dedupe.

What can I paste or upload into Count Lines?
Paste the text. An empty box counts as 0. A final newline adds a line the same way a split does.
What output does Count Lines give me?
A single integer. There is no per-line breakdown.
Is Count Lines free, and is my input private?
Yes — Your input is processed in memory for this request only. It is not saved to disk or the database, and it is cleared after the tool finishes.
Does a trailing newline add a line?
Yes. Text split on newlines counts the empty piece after a final newline. Remove that newline if you want one count per visible row only.
