Line Counter

Count total lines, blank lines, and non-blank lines in your text. Useful for code review, log analysis, and document formatting.

Line Counting Metrics

| Metric | Description | Total linesAll lines including blank Non-blank linesLines with content Blank linesEmpty or whitespace-only lines | Code lines | Non-comment, non-blank (for code) |

Line Counter Implementation

``javascript function countLines(text) { const lines = text.split('\n'); const totalLines = lines.length; const blankLines = lines.filter(line => line.trim() === '').length; const nonBlankLines = totalLines - blankLines;

return { totalLines, blankLines, nonBlankLines }; } ``

Common Use Cases

Line counting is essential for code metrics (lines of code), log file analysis, data file row counts, and ensuring documents meet line requirements for academic or legal submissions.

Frequently Asked Questions

How are blank lines counted?

Blank lines are lines that contain only whitespace (spaces, tabs) or are completely empty. Our tool counts these separately from lines containing actual content.

Does the last line need a newline?

Files can end with or without a trailing newline. Our tool counts lines consistently regardless. A file with content and no trailing newline still counts as having that line.

What about lines with only spaces?

Lines containing only whitespace (spaces or tabs but no visible characters) are counted as blank lines. This matches how most code editors and tools treat whitespace-only lines.
