How Does It Work?
- Paste your listAnything with one item per line: emails, SKUs, URLs, names, log entries or code.
- Read the countsTotal lines includes blanks; non-empty ignores them. Unique and duplicate counts are based on the non-empty lines.
- Copy the numbered versionHandy when you need to refer to line 47 of a list in a message or ticket.
What Is It Used For?
Lists arrive as plain text far more often than as spreadsheets — pasted from an email, exported from a system, copied out of a log. Counting the lines, and knowing how many are repeats, is usually the first thing you want to know before doing anything with them.
- Checking how many records are in a pasted export before importing them.
- Verifying that a mailing list has the number of addresses you expect.
- Counting lines of code or configuration in a snippet.
- Spotting that a list contains duplicates before you act on it.
- Referring to a specific line number when reporting a problem.
