What does 'trim lines' do?

Trim lines removes leading and trailing whitespace (spaces and tabs) from each individual line, while preserving the content and spacing within the line.

What does 'collapse multiple spaces' mean?

It replaces sequences of two or more consecutive space characters with a single space. For example, 'hello world' becomes 'hello world'.

Can I use multiple options at once?
