Frequently Asked Questions
What whitespace is removed?
Any spaces and tabs at the start or end of each line. Whitespace inside an item, such as the space between two words, is left alone.
Does it change the order of items?
No. Every item stays exactly where it was; only the surrounding whitespace is cleaned up.
Does it remove blank lines?
No. A line that was only spaces becomes empty but keeps its place. To drop blanks entirely, run a flatten or remove-empty step.
Why does trailing whitespace matter?
Hidden spaces at the end of lines can break comparisons, imports, and code. Trimming makes the data predictable.
Is my list uploaded?
No. The trimming runs in your browser and your list never leaves the tab.
