Tom
Thank you ... for this and the tip to open the other workbook.

When testing, I noted that writing a loop within a workbook was far quicker
than the code I have looping to an external workbook. Would I be correct in
thinking each time the formula is written during a loop, Excel look for the
external connection, despite calculations and screen updating being off?

Also, you can enter a row oriented formula template in one command

Range("B2:B100").formula =
"=Index([Book1.xls]Sheet1!$A$1:$A$1000,Match(A2,[Book1.xls]Sheet1!$F$1:$F$10
0,0),1)"

as an example

Sorry if you've read this. However, I didn't see the question appear in
my
reader.

I have a project that includes parsing a .txt file into Excel. Included
in
the fields imported is an EmplID. I need to retrieve data from separate
workbooks based on this. My experiment with Index and Match produced slow
results when linked to one other workbook (about a minute for 4000
records).
I am currently looping using i to increment the row number in the lookup
formula.

Is there a faster method (either not using Index/Match or not looping)?
