使用外部数据源在Excel中求和

Question

I am trying to calculate some data in a excel using external excel file. My formula is like;

=SUMPRODUCT(--('[Stock Register.xlsx]Stock Code 1'!$E$3:$E$500="Issued to Sanitary Syndicate"),'[Stock Register.xlsx]Stock Code 1'!$C$3:$C$500)

This works fine for me. But I need the sheet (Stock Code 1) being changed automatically when dragging or pasting on the next rows.

I am using it a new workbook using external data source (Stock Register.xlsx). Stock Register consisting of 570 sheets and for each sheets I need to display results in that New Workbook in cell (C1) using above formula and drag it to cell (C70).

Answer 1

You can add two columns before the SUMPRODUCT .

First column, say this is in column B , will need to have CONCATENATE to the external spreadsheet that you want to link to. For example:

=CONCATENATE("[Stock Register.xlsx]Stock Code",ROW(A1),"!$E$3:$E$500")

This should give you [Stock Register.xlsx]Stock Code 1!$E$3:$E$500 .

Same thing for the second column that you want for $C$3:$C$500 so you can get [Stock Register.xlsx]Stock Code 1!$C$3:$C$500 .

Then the third column, say this is in column D , will be the SUMPRODUCT formula that with INDIRECT . And here you go:

=SUMPRODUCT(--(INDIRECT(B1)="Issued to Sanitary Syndicate"),INDIRECT(C1))

Hope this helps.

PS One thing I noticed when combining all three into one column, the formula wouldn't work. Someone probably can come up a better way but to have a reference address sit next to the result may benefit you to debug down the road. Just a thought.

UPDATED: Okay, I was able to recreate what I described below. Maybe it is easier to show you in screenshots:

1. See I created three sheets in Stock Register.xlsx file, Stock Code 1 sheet looks like below that values under column C and descriptions under column E .
   
   And another spreadsheet called Results.xlsx . Column B has a formula of =CONCATENATE("'[Stock Register.xlsx]Stock Code ",ROW(A1),"'!$E$3:$E$500") .

2. In this picture, Stock Code 2 sheet looks like below.
   
   Column C in Results.xlsx spreadsheet has a formula of =CONCATENATE("'[Stock Register.xlsx]Stock Code ",ROW(A1),"'!$C$3:$C$500") .

3. In this picture, Stock Code 3 sheet looks like below.
   
   Column D in Results.xlsx spreadsheet has a formula of =SUMPRODUCT(--(INDIRECT(B1)="Issued to Sanitary Syndicate"),INDIRECT(C1)) .

Try again and let me know.
