Using a Text / Data output as a cell reference
 

I am trying to use the end of a column as a divisor and need to convert what
i guess is text into an actual cell reference if possible.
In column A, say there are 13 data points ending at cell A13.
I then try to turn that into a cell reference with the formula
="A"&TEXT(COUNTA(A1:A13,),"0") I put this formula in B1
the output of this is then A13
what i need this to do, is be able to divide any cell by A13.
The reason I am going through all this trouble is that there are many
columns and each has a different # of data points.
I hope this is somewhat clear. Thanks for any help

For what you have asked you can just wrap it with INDIRECT(......) which
converts a textual representation of a reference to an actual reference.

Another way to find the last value:-

=LOOKUP(9.99999999999999E+307,A:A) for last numeric entry in a column

=LOOKUP(9.99999999999999E+307,1:1) for last numeric entry in a row

=LOOKUP(REPT("z",255),A:A) for last text entry in a column

=LOOKUP(REPT("z",255),1:1) for last text entry in a row
