Common questions
What does trimming whitespace do to a CSV?
It removes spaces at the start and end of each cell and collapses repeated spaces, so values like " London " and "London" match when you sort, filter, join or de-duplicate.
Why does whitespace break VLOOKUP, joins and imports?
Spreadsheets and databases compare text exactly, so an invisible trailing space makes two otherwise equal values different. Trimming fixes those silent mismatches.
