About the Line Counter
A line counter tells you how many lines a block of text or code contains, which is handy for logs, CSV data, lists and source files.
It separates total lines from non-empty and blank lines so you know how much of your text is actual content.
It also counts unique non-empty lines and measures the longest line, which helps when checking for duplicates or overly long rows.

Frequently asked questions
- How are lines counted?
- The text is split on line breaks, supporting Windows (CRLF) and Unix (LF) endings. Each segment between breaks counts as one line.
- What counts as a blank line?
- A line that is empty or contains only spaces or tabs is counted as blank.
- Is my text uploaded anywhere?
- No. Counting happens entirely in your browser, so your text never leaves your device.
