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.
Newline counter tool 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!

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.
