Return the address of last non-empty string cell

I've been researching this for a bit and can't find a solution. Thanks for the help.

Without using VBA, I'd like to:

Return the cell address of that last cell in a column with a numerical value in it.

• The problem is, the data is populated with a formula that leaves empty strings (it returns "") instead of actual empty cells. I've researched that there is no way to write a formula that can return a truly empty cell.

• The ROWS function counts empty strings as values, so I need a way to use an if statement in conjunction with ROWS and ADDRESS to return the cell address of the last cell in a column with a numerical value.
