newline counter

world's simplest string tool

Free online utility that finds the number of newlines in a string. Just load your multi-line string and this utility will automatically calculate the number of lines in it. There are no intrusive ads, popups or nonsense, just a simple newlines counter. Load a multi-line string – get the number of lines in it. Created for developers by developers from team Browserling.

᠎᠎᠎          Tool Options

Line Counter

Calculate the total amount
of newlines in a string.
Count only those lines
that contain characters.
Count only those lines that
don't contain any characters.

Whitespace

Delete all spaces and tabs
that are at the ends of
the input strings.
If the option is activated, then
lines that consist solely of
spaces and tabs are
considered empty.

What is a newline counter?

This tool counts how many newline characters are in the given multi-line string. By default, it finds the total amount of newlines. This is the same as finding how many lines there are as each line is terminated by a newline symbol. You can also select a mode that counts only those lines that contain characters or vice versa, counts only lines that contain no characters (empty lines). You can easily switch between these three modes and compare the results. We also have an additional option for the cases when lines contain just spaces and tabs. These characters are impossible to see as they are whitespace characters. This option removes all whitespaces and allows you to include these lines in the empty lines count. Note that every line ends with an implicit newline, so for short strings, the count is 1. Stringabulous!

A List of Galaxies

This example loads a multi-line string that contains galaxies and returns the total number of newlines in this string. The empty lines are included in the count.

Islands of the World

In this example, we count the number of non-empty lines in the world's largest islands list. We also use the "Remove Invisible Whitespaces" option to exclude lines that consist solely of spaces and tabs from the output amount. We get 10 lines in the output this way. If we didn't remove spaces and tabs, we'd get 12 as 2 lines contain just these symbols.
