What is this?

Line Counter tells you exactly how many lines your text contains — total, non-empty and unique — and can prefix each line with a number.

How it works

The tool splits your text on line breaks and reports the counts live. Enabling line numbers adds a padded index in front of every line so the columns stay aligned.

Use cases

  • Count rows in a CSV or log file.
  • Verify how many items are in a list.
  • Add line numbers for referencing code or notes.
  • Check line limits for forms or imports.

FAQ

Does the last line count if there is no trailing newline?
Yes. The final line is always counted whether or not the text ends with a line break.
How are unique lines determined?
Unique lines are counted by exact string match after splitting on line breaks.
