Step 1: Set Up Your Data

Assume you have the following data in two separate Excel worksheets:

Step 2: Create a New Column for Matching

In your “Customer Information” worksheet, you’ll create a new column where you want to display the most recent purchase date for each customer. You can name this column “Most Recent Purchase Date.”

Step 3: Use the MAX Function with IF and VLOOKUP

In the “Most Recent Purchase Date” column, use the following formula to find the most recent purchase date for each customer:

=MAX(IF([Customer ID]=[Customer ID from Transaction Data],[Purchase Date from Transaction Data],””))


  • [Customer ID] refers to the Customer ID in your “Customer Information” worksheet.
  • [Customer ID from Transaction Data]refers to the Customer ID in your “Transaction Data” worksheet.
  • [Purchase Date from Transaction Data] refers to the Purchase Date in your “Transaction Data” worksheet.

Step 4: Enter the Formula as an Array Formula

Since this formula involves an array calculation, you need to enter it as an array formula by pressing Ctrl + Shift + Enter  instead of just Enter. Excel will automatically add curly braces {} around the formula to indicate that it’s an array formula.

Step 5: Result

After entering the formula correctly, you’ll see the “Most Recent Purchase Date” column populated with the most recent purchase date for each customer in your “Customer Information” worksheet.

Your updated “Customer Information” worksheet will look something like this:
