Hello,
A folder contains about 1200 workbooks, named based on client's account
numbers who make international calls.

A workbook named 31648.xls looks like this.

I have made another workbook to get details of minutes consumed on a
perticular date from all 1200 workbooks using sumproduct funtion. This sheet
looks like this.

32207 0.00
32293 10.00
to 1200..

"Minutes" coloumn above contains this function for 31906.xls. (Account
number changes from cell to cell.)
=SUMPRODUCT(('F:\CONFERENCE\[31906.xls]Sheet1'!$A$5:$A$500=$F$1)*('F:\CONFERENCE\[31906.xls]Sheet1'!$E$5:$E$500))

G1 contains =SUM(B:B)

Right now, when i type a date in F1, sumproduct gets total minutes consumed
by all 1200 clients on that perticular date. What i want is a coloumn "DATE"
and coloumn next to it should display the minutes consumed on that perticular
date.

Like this :

I enter date in coloumn A and get minutes automatically in coloumn B.

Sunday, June 05, 2005 2745
Monday, June 06, 2005 1207
Tuesday, June 07, 2005 1917

Right now i am manually inserting dates in coloumn B, after getting the
minutes for individual dates using the above sheet. This is a very slow
process, because once i enter a date in F1, sheet takes about 2 minutes to
calculate minutes on that perticular Date.

Suggestions?
Thanks.

Well, you could use a Data Table (DataTable...). Your Sum(B:B) formula
would be at the top of the table and the dates would go down the left column.
It'll take a long time to calculate, but should do the trick. I'd try it
with a samll sample of dates first - maybe 3 to 5 dates - and then expand it
to the full range of dates if it gives you what you want.

Personally, I'd see about the possibility of putting this into a database -
Access, MSDE, or SQL Server - and running queries or reports against the
database. That's one area where databases have an enormous advantage over
Excel.
