# Excel Offset Formula Question

In the attached spreadsheet, I have two columns of data, with the top row returning the last cell of data with an offset formula, as it should. However, I'd like to get a formula that returns the last value in the column -- only if the one next to it is filled.

In my example, I'd like the date 01/31 returned, instead of the date 02/04.

How do I write this type of formula?

Thanks!

OK, I am not sure if I am grasping the question fully, but attached is the file ammended for the first column to return the coresponding cell to column B...

the formula is the same as in B1 except that is OFFSETS -1 from the result of B1

=OFFSET(B\$2,MATCH(MAX(B\$2:B363)+1,B\$2:B363,1)-1,-1)

You could use LOOKUP to get the last time from column B in B1, i.e.

=LOOKUP(9.99E+307,B3:B366)

then in A1 to get the corresponding date try

=LOOKUP(9.99E+307,B3:B366,A3:A366)

Thanks, guys. I like the OFFSET rather than the LOOKUP in this case, because only one formula needs to be entered. Works perfectly ... thanks!

I'm not suggesting you use any more formulas than you are currently using - the first LOOKUP replaces your B1 formula and the second replaces the A1 formula.

LOOKUP and MATCH use the same technique here to find the last value, but with MATCH you only get the position....and OFFSET is being used to get the value from that position.......but with LOOKUP you don't need that two stage approach - it just gives you the last value directly......
