Make Sentence Case

Hi, has anyone managed to format columns to Sentence Case? I’m seeing a lot of entries for names in lower case which isn’t a big issue but doesn’t look great when emails or reports are triggered.

Instead of gary Brett or gary brett, I’d like to format to Gary Brett on the front end like we can in Excel.

I know I could create a new formula column but hoped to do this on current field to save overheads.

Thank you
