i have a folder with .xls files which are all named like xxx_day_month_year.xls and i want to look up for some values in this files by selected date.
I came to next solution:
=VLOOKUP(B3;INDIRECT("'G:\xxxxxxx..\"&G3&"."&G4&".2014_test.xls]HL'!$C:$D");2;FALSE)
Where cells G3 and G4 are desired day and month.
But this only works if I have opened documents in which I look up for data. Is there a way that this formula is going to work in independent document?
