Dan,

There is no partcular reason, it can be increased down to cell 65,536.

Thanks for commenting!

Received with many thanks!!!

I noticed that you have limited the height definition for the range to 10,000 cells. Is there any particular reason for this (ie. slower processing when more cells are included in the range), or can the height theoretically be increased down to cell 65,536?

I have resolved this now! Originally I wanted to define two separate columns as the two ranges as the data being impoted into them varies month by month i.e the data is dynamic. Through experimentation and testing, I discovered that your formula only works for statically defined ranges. It would be great to be able to adapt your formula to be used with dynamic ranges, but that is, sadly, beyond my excel scope and knowledge. If you are able to provide this, I would be deeply grateful, but if you are not, then I will use my work-around. Many thanks.

Hey Oscar!!

Many thanks for sharing your excel knowledge...Ive been trying to figure this out for a while!...

I copied the formula into my worksheet (Im using excel 2003), but (and I cant see why), but the formula has only copied the first named range column (GN_LIST in column H) into the merged column (column M).

If I change the very last range name to the second list name (SH_LIST in column L), then the second column only is entered into the merged column.

My formula is as follows:

=IF(ISERROR(INDEX(GN_LIST, ROWS($M$1:M2))), IF(ISERROR(INDEX(SH_LIST, ROWS($M$1:M2)-ROWS(GN_LIST))), "", INDEX(SH_LIST, ROWS($M$1:M2)-ROWS(GN_LIST))), INDEX(GN_LIST, ROWS($M$1:M2)))

Can you PLEASE help?!? I am baffled...

Regards

Windfery,

I am not sure I understand, automate the length of the merge column?
You want the named ranges to expand whenever new values are added, right?

I've never used the INDEX function before and this is a great use for it. My last puzzle is to automate the length of the merge column. Been trying to do with with a dynamic table height but no luck. anyone got ideas?

Cheers

macutan Filter common dates from two columns and return unique distinct dates sorted smallest to largest Array formula in cell D3:

=SMALL(IF((COUNTIF(List2, List1)>0)*(COUNTIF($D$2:D2, List1)=0), List1, ""), 1)

How to create an array formula Copy (Ctrl + c) and paste (Ctrl + v) array formula into formula bar. Press and hold Ctrl + Shift. Press Enter once. Release all keys. Download excel file sort-common-dates-from-two-columns.xls Excel 97-2003 *.xls
