从Excel中的多个工作表返回数据

Question

How do you create formulas that will return the totals, averages, counts, min, max, etc from different worksheets? The columns (that exist) are consistent in their header information, but may or may not be different from one sheet to the next, column number wise. Let's say I have 7 tabs of data, some or all of them may contain a column heading of beans, for example, but the column numbers may or may not be consistent across all tabs, where present. Their actual locations within the worksheet are completely dynamic.

My spreadsheet has several tabs of raw data that I want to compare against in a summary/report sheet. I'm sure this can be done but I am afraid it is a little too far beyond the capability of this old brain.

I've thought about and toyed with a bunch of formulas using indirect, index, match and just can't figure it out. Your help would be most appreciated. Thanks

Here's a possible function only solution. The final result will look like:

We will use four(4) primary functions:

1. ADDRESS
2. INDIRECT
3. MATCH
4. LEFT

^{Note: Just follow the link if you have question on how to use these functions}

The formula: This is in cell C4 Above

=AVERAGE(
         INDIRECT(
                  "'"& C$3 & "'!" &                                          
                  LEFT(ADDRESS(1,MATCH($E$2,INDIRECT("'"&C$3&"'!1:1"),0),4,1),1)
                  & ":" &
                  LEFT(ADDRESS(1,MATCH($E$2,INDIRECT("'"&C$3&"'!1:1"),0),4,1),1)
                  )
        )

Edit1: To handle the comment below for headers beyond 26, change this

LEFT(ADDRESS(1,MATCH($E$2,INDIRECT("'"&C$3&"'!1:1"),0),4,1),1)

to this:

SUBSTITUTE(ADDRESS(1,MATCH($E$2,INDIRECT("'"&C$3&"'!1:1"),0),4,1),"1","")

Basically what is does is:

• Find where the header Bean is located using MATCH function. To do that, you will have to incorporate the use of INDIRECT since your sheet name is dynamic (in this example, your sheet name is in C3 - Data1 ). (I assumed all your headers are in 1st row, I use 1:1 in there) . ^{Note: In this example, Bean is in column H of Data1 sheet}

   MATCH($E$2,INDIRECT("'"&C$3&"'!1:1"),0) <~~ returns 8 

• After finding where it is, we need to get the entire column address so we can apply counting and summing functions (eg SUM,COUNT,AVERAGE etc...). To do that we use the ADDRESS function combined with LEFT to get the column letter.

   LEFT(ADDRESS(1,MATCH($E$2,INDIRECT("'"&C$3&"'!1:1"),0),4,1),1) <~~ returns H 

• Then we just repeat that formula and connect it with : to get H:H

• Now that we have the column address, we simply connect it again with the sheet name and apply the final INDIRECT function plus the counting and/or summing function of your choice.

Sample formula of Total in C5 :

Sample formula of Max in C6 :

Finally, all you have to do is copy the formula across all columns with sheet name.
Just add sheet names beside the last one and copy formula. That's it. I hope this is close to what you want and I hope that all the functions I used are available in Excel 2000.
