Frequently Asked Questions

What spaces are removed?

Only leading (before) and trailing (after) spaces are removed. Spaces within text are preserved. For example, " hello world " becomes "hello world".

Why does whitespace matter?

Extra spaces can cause database lookups to fail, create duplicate-looking entries, and break data imports. Trimming prevents these issues.

Are tabs and newlines removed?

Yes, all whitespace characters (spaces, tabs, newlines) at the start and end of cells are removed.
