How to use LOWER

LOWER is UPPER the other way round. Every letter comes back in lower case.

It is used for building a key: strip the case out of both sides of a comparison and inconsistent typing stops mattering.

As with UPPER, it does nothing about spaces, so it does not fix a padded value on its own.

=LOWER(TRIM(B7))=LOWER(TRIM(B2))Rows 2 and 7 are the same supplier, entered by two different people. Once both sides are trimmed and lower-cased, the comparison is about the name rather than about the typing.TRUE

Notes

  • Excel compares text without regard to case anyway, so LOWER is about producing a tidy key, not about making a comparison work.
