在Excel中交叉引用数据

Question

I am trying to start an advertisement analytics tool for my business. I have an Excel spreadsheet with 3 Sheets. Sheet 1 contains data about the advert clickers, Sheet 2 contains information about the product buyers and Sheet 3 should collect data based on cross-referencing data between Sheets 1 & 2.

The columns in Sheet 1 are as follows:

    A           B       C               D              E                F       G
------------------------------------------------------------------------------------
product type, tag, click date/time, IP address, expiry time (days), expiry date/time 

Each row represents a click. The expiry time (days) is determined by the product type, and the expiry time/date is the expiry time (days) added to the click date/time. The tag is a code that tells me where the link was found by the clicker.

The columns in Sheet 2 are as follows:

       A           B               C
---------------------------------------------
product type, IP address, purchase date/time. 

Each row represents a product sale.

There are more rows in Sheet 2 than there are in Sheet 1.

There are three pieces of information that I want to match between Sheet 1 and Sheet 2: IP address, product type and whether the purchase date/time (Sheet 2) falls between the click date/time and the expiry date/time . I have made formulas that can verify whether this occurs but only for assigned cells in each Sheet.

I am trying to get Excel to match one row from Sheet 1 to all rows in Sheet 2. As there are more rows in Sheet 2 than in Sheet 1, there could be multiple matches for each tag as defined in Sheet 1, as customers may decide to buy more than one product after clicking the link.

Is there a way to try and match the data between the two Sheets and then collect the number of matches in Sheet 3? It may be easier to achieve if the IP address and product type are matched first and then to try and see if the purchase date/time falls within the click date/time and the expiry date/time .

Any help on this would be greatly appreciated and thanks so much in advance. This has been bugging me for a while and I can't figure it out.

Answer 1

I think I have a good start for you. With vlookup you can specify multiple criteria. First start by bringing in the useful data into one sheet - I would take column D and E of "sheet2" and use these:

In D:

=VLOOKUP(A2& " "&B2,Sheet1!$A$2:[BOTTOM RIGHT OF TABLE],3)

The 3 at the end specifies you want to return the click date.

In E:

=VLOOKUP(A2& " "&B2,Sheet1!$A$2:[BOTTOM RIGHT OF TABLE],6)

The 4 at the end specifies you want to retune the expiry date.

Once they are on one sheet, you can do an if statement comparison to see if the date (Column C) falls between your two dates (Column D and E). Here is the if statement for that:

=IF(AND(C2>=D2,C2<=E2),1,0)

There is one shortfall to this, and that is if there are multiple matches for both product AND ip - this will only return 1, but otherwise you're talking about scripting something in VBA.

Answer 2

In excel you can refer cell based on sheet like this and make it on third sheet:

=Sheet1!A1+Sheet2!A2
