How accurate is the Line Counter tool?
The Line Counter provides 100% accurate results by counting every line break in your text. It follows standard counting conventions where each line separator (including empty lines) is counted as one line. This matches how most programming languages and text editors calculate line numbers, ensuring consistency with development environments and document processing software.
Can I count lines in code files?
Yes, our tool works perfectly with all programming languages and code formats. It counts physical lines of code (including comments and blank lines) regardless of file extension. For code-specific metrics like logical lines or statement counts, consider specialized code analysis tools.
Is there a file size limit?
There's no strict file size limit, but very large documents (10MB+) may affect browser performance. For optimal results, we recommend processing files under 50,000 lines at a time. The tool handles all common text formats including TXT, CSV, JSON, XML, and source code files.
