About Line Counter

Welcome to the Line Counter, a comprehensive free online tool for counting lines in any text with advanced statistics and visual analysis. Whether you are counting lines in a document, analyzing code files, or getting detailed text statistics, this tool provides instant, accurate results with a beautiful interface.

How Do I Count Lines in a Text File?

Simply paste your text into the Line Counter tool and click "Count Lines". The tool will instantly show the total number of lines, including options to count only non-blank lines or code lines (excluding comments). You can also see detailed statistics like word count, character count, and paragraph count.

Features and Capabilities

What is the Difference Between Total Lines and Non-Blank Lines?

Total lines counts every line in your text, including empty lines that contain no characters or only whitespace. Non-blank lines counts only lines that have actual content. For example, if you have 10 lines of text with 3 empty lines between paragraphs, the total would be 10 but non-blank would be 7.

How Does the Code Analysis Mode Work?

Code analysis mode counts lines of actual code by excluding comment lines. It recognizes comment syntax from multiple programming languages:

• Python, Ruby, Perl, Bash: Lines starting with #
• JavaScript, Java, C, C++: Lines starting with //
• SQL, Lua, Haskell: Lines starting with --
• HTML: Lines with <!-- and -->
• CSS, Multi-line comments: Lines starting with /* or */
• LaTeX, Matlab: Lines starting with %
• Assembly, INI files: Lines starting with ;
