Question: In Excel, Excel VBA, and Google Sheets cell (and range) address may be redefined by the user as special `Named Range` objects, is the use of these objects allowed by default - that is, may it be assumed that cell `A1` is renamed to `A` and Cell `B1` is renamed to `b` by default such as is done in [this answer](https://codegolf.stackexchange.com/a/150068/61846)?

It is invalid to assume that the user has manually redefined a given range to a shorter name. You may, however do so programmatically as part of your answer. An example of valid code renaming range `[A1]` to `[A]` in VBA is included below
