Best way to match a cell value on worksheet
HelloI am trying to do a vlookup formula but I an not getting the result I want. The reason I think is that some of the cells in the array table are in text format. I have an error that I can pick that will make this numbers into numbers, however, I can't do this because this won't match the value I am looking up. My formula is this =vlookup(b2,'c:\data\test\Invoice\[log.xls]sheet1'$d1:$G$1500,3). Would a match or an index formula work or is there a way for th lookup to look for values and text too. Any help would be greatly appreciated. Thank you.

If B2 is a real number and column 1 of your range contains real numbers, with some represented as text, this ARRAY formula should work:
=INDEX(sheet1!$F1:$F$1500,match(B2,1*sheet1!$D1:$D $1500,0))
(conform with: ALT+CTRL+Enter)Last edited by kweaver; 20131108 at 16:59.

Try this:
Code:=IF(ISNUMBER(match(B2,'c:\data\test\Invoice\[log.xls]sheet1'!$D1:$d$1500)),VLOOKUP(B2,'c:\data\test\Invoice\[log.xls]sheet1'!$D1:$G$1500,3),VLOOKUP(B2&"",'c:\data\test\Invoice\[log.xls]sheet1'!$D1:$G$1500,3))

PS this is an approximate match, so the routine expects the series to be sorted and if it is not it can yield odd results...
The exact match version is:
Code:=IF(ISNUMBER(match(B2,'c:\data\test\Invoice\[log.xls]sheet1'!$D1:$d$1500,0)),VLOOKUP(B2,'c:\data\test\Invoice\[log.xls]sheet1'!$D1:$G$1500,3,0),VLOOKUP(B2&"",'c:\data\test\Invoice\[log.xls]sheet1'!$D1:$G$1500,3,0))

Steve, you tend not to like array formulas. Why? Are they inefficient? Is it better to do an IF test first and make the decision after that?

I couldn't get either formula to work. There is an arrow down within the cell that gives me the options to convert text to number, correct error, ignore error, etc.
Kweaver: Do you need to specify the file path and worksheet name from where to look at the information in the index formula?
sdckapr: I get an N/A with the formula you provided.
Thank you both for your help.

kweaver:
I uise arrays when needed. When not needed, I do not use them. They can be inefficient if there are multiple ones. If you use 1 array for a range of cells, the workbook can be problematic in the future as inserting a deleting rows can become an issue as you can't easily change the array.
Seba:
Could you attach an example file, demonstrating the issue. An #NA error for both tests suggests to me that the list is not sorted ...

Seba  yes, you need to put the full path in my array formula. I just didn't type it.

sdckaprYou are right the list is not sorted and unfortunately I can't sort it because we track invoice base on the date they come in and not by invoice number.
KweaverI will try it again and see if that works. Quick questionCan I make the array formula include empty rows. This are needed since I will be providing the formula to staff to copy and paste.

If not sorted, the partial match system does not work. The exact match should work however. But if a match is not found you will get an #NA error...
The exact match starts testing at the start and goes onebyone through the list. The partial match presumes there is a sort order so can jump around the list and not have to look at all for more efficient lookups.
