Uppercase to Lowercase letter and vice versa

[gitts77]

I am using FreeOffice Planmaker 2024 more like doing a Microsoft Excel WorkSheet.
Some of the information was already in Uppercase, and some are in Lowercase.
I want to make all the information to be in Lowercase. How do I do that, without physically having to type those already in Uppercase to Lowercase?

Depends on what you want:

1. You can use function =LOWER(String) for converting it to lowercase dynamically.
2. Shift+F3 to convert the string in a cell at one time, cycling through different casing options.
