Naming a Cell in Numbers Can you define a cell's name in Numbers for use in formulas across a workbook like you can in Excel?
Numbers has some limitations when compared with Excel.

You can't reference sheets in a different Numbers file, for example.

The best you can do is to reference a cell withing the same file but on a different worksheet.  This works the same in Numbers as it does in Excel.
