Line Counter

Our free Line Counter is an essential online tool for developers, data analysts, writers, and students who need precise measurements of their text. Whether you are measuring the length of a script, parsing CSV data rows, or checking a list against an expected row count—this tool gives you instant, accurate results right in your browser.

Live Line Numbers & Synchronized Scrolling

Unlike a plain textarea, the Line Counter renders a live line-number gutter that stays perfectly in sync as you scroll. This mirrors the experience of a code editor like VS Code or Sublime Text—making it easy to navigate large pastes and spot exactly where your line count changes.

Blank Line Detection

Text files, code snippets, and copied prose often contain invisible whitespace and trailing empty lines that bloat your count. The Line Counter distinguishes between Total Lines (absolute count, including all line breaks) and Non-Blank Lines (lines with at least one visible character). Switch between modes using the Counting Mode dropdown to see the exact figure you need.

Who Uses a Line Counter?

• Developers & Programmers: Measure Lines of Code (LOC) in a snippet instantly—no terminal, no IDE.
• Data Professionals: Verify that a pasted list of emails, IDs, or CSV rows exactly matches the count you expect before importing.
• Writers & Editors: Track paragraph counts and character totals to meet strict word-processor or submission format rules.
• Students: Quickly confirm that assignment text meets minimum line or paragraph requirements.

100% Private — Runs Locally in Your Browser

All analysis—character counting, line counting, blank-line detection—is executed entirely in JavaScript on your device. We never transmit, store, or log any text you paste into the tool.
