What is the Line Counter?

The free Line Counter counts every line in your text and reports four instant stats: Total Lines, Non-Empty Lines, Empty Lines, and Longest Line (in characters). It is invaluable for developers checking log files, data analysts counting CSV rows, and writers reviewing lists.

→ Count rows in a CSV or TSV file before importing into a spreadsheet or database.
→ Measure log file depth to estimate processing time.
→ Verify that a list has the expected number of entries.
→ Find the longest line in source code to check against line-length style rules.
→ Audit blank lines in formatted text or markdown files.

How to Use the Line Counter

1 Paste your text or code into the text area labelled "Paste your text or code here…".
2 Read Total Lines for every line including blanks.
3 Check Non-Empty Lines for lines that contain at least one character.
4 Empty Lines shows how many completely blank lines exist.
5 Longest Line reports the character length of the longest single line.
