TRIM FunctionTips and Tricks
TRIM Does Not Remove Non-Breaking Spaces: Some web data contains non-breaking spaces (CHAR(160)), which TRIM does not remove. Use SUBSTITUTE(A1, CHAR(160), "") before TRIM.
Works Only on Text: If numbers appear as text due to spaces, TRIM can help clean them, but they may still need conversion using VALUE().
Use in Nested Formulas: Combine TRIM with VLOOKUP and MATCH to ensure accurate lookups:
=VLOOKUP(TRIM(A1), B1:C10, 2, FALSE)Practice Problems
- Problem 1: Remove extra spaces from a list of names in column A using TRIM.
