You can use the .strip() method to remove all leading and trailing spaces or line breaks from the data.

For example, if the order's note field looks like this:

    

   hello
world   

Using this formula below:

{{ note }}.strip()

Will output:

hello
world

This is also useful when stripping out HTML code where there might be excess spaces and line breaks in the HTML data.  You can apply the strip_html_tags() function and then strip out leadingand trailing spaces/line breaks as well like this:

strip_html_tags({{ body_html }}).strip()
