How to use

Paste text, a list, log, CSV file, or multiline export into the input field.
The counter automatically shows total lines, non-empty lines, empty lines, and whitespace-only lines.
If needed, configure empty line handling, trailing newline behavior, and line length limit.
Copy the statistics and use them to estimate data volume, logs, lists, CSV files, or text exports.

More about this tool

Line Counter helps you quickly evaluate the structure of multiline text, logs, lists, CSV files, tables, and text exports. The tool shows total lines, non-empty and empty lines, whitespace-only lines, average line length, the longest line, and the number of lines longer than a set limit. This is convenient before data import, splitting into parts, log review, list preparation, and text file analysis.

Frequently Asked Questions

What does the line counter measure?

The tool counts total lines, non-empty lines, empty lines, whitespace-only lines, average line length, and lines longer than a set limit.

How is an empty line counted?

An empty line has no visible characters. If "Treat whitespace-only lines as empty" is enabled, lines made of spaces and tabs are counted as empty too.

Is the last line counted if text ends with a newline?

That depends on the setting. You can count or ignore the final empty line after a trailing newline.

Can overly long lines be found?

Yes. Set a line length limit and the tool shows how many lines exceed it, along with the first matching lines with their numbers and lengths.

Is the tool suitable for logs and CSV?

Yes. The service is convenient for estimating the volume of logs, CSV files, lists, exports, and other multiline data.

How is this different from a character counter?

A character counter shows overall text length, words, and bytes. A line counter focuses on line structure: empty lines, non-empty lines, line length, and lines longer than a limit.

Is my data sent to the server?

No. Text is processed locally in your browser and is not sent to the server.

Do I need to register?

No. The tool works immediately and does not require registration.
