Line Counter Utility

Counting lines in large documents, log files, or source code can be a tedious and error-prone process when done manually. Our Line Counter provides an instant, accurate breakdown of total lines and non-empty lines. It runs entirely in your browser, guaranteeing maximum speed and privacy for massive datasets.

Why Distinguish Empty Lines?

Just knowing the absolute line count isn't always enough, especially for developers and analysts:

  • Code Auditing: Measuring lines of code (LOC) is more accurate when you subtract blank spacing lines.
  • Data Validation: Ensure your CSV or JSON exports contain the exact number of data rows expected, ignoring trailing blank lines.
  • Log Analysis: Quickly assess the volume of server error logs without being skewed by empty formatting breaks.

100% Privacy and Security

Whether you're pasting proprietary source code, confidential server logs, or private user data, your information remains safe. Our utility runs entirely on your local machine using client-side JavaScript. Data never leaves your computer.

Frequently Asked Questions

What is considered a "non-empty" line?

A non-empty line is any line that contains at least one visible character. Lines containing only spaces or tabs are stripped out and considered empty.

Can it handle huge files?

Yes. The tool can process megabytes of text containing tens of thousands of lines almost instantly, limited only by your browser's memory cap.

Use it from the API

Everything this page does is also available as a REST endpoint, so you can call Line Counter from your own code, a script or a CI pipeline.

Bash
curl "https://api.toolsxpo.com/v1/line-counter" \
  -H "Authorization: Bearer txp_live_YOUR_KEY"

The endpoint returns a JSON envelope ({ ok, data, meta }) and costs 1 credit per successful call. Try it in the playground or browse the full API reference.
