Strip stray spaces from item codes with TRIM
Clean codes that arrive padded with spaces so lookups stop failing on them.
TRIM
Removes the spaces before and after text, and collapses repeated spaces inside it. Below is 1 interactive exercise that puts it to work on realistic business data — you write the formula, and get told exactly what went wrong when it does not work.
TRIM(text)
Need a refresher? Learn TRIM — syntax, a worked example and where it goes wrong.
Ordered from most approachable to hardest.
Removes the spaces before and after text, and collapses repeated spaces inside it. It belongs to the text functions family, and it shows up constantly in real work — which is why it is worth being genuinely fluent rather than merely familiar.
Reading about a function is not the same as being able to write it. The exercises on this page exist because the gap between recognising TRIM and producing it from memory, correctly, on data you have not seen before, only closes by doing it.
