We can use the LOOKUP function and the TEXT function to get the last entry by Month and Year in a data. The steps below will walk through the process.

Figure 1: How to Get Last entry by Month and Year

General Formula

=LOOKUP(2,1/(TEXT(dates,"mmyy")=TEXT(A1,"mmyy")),values)

Formula

=LOOKUP(2,1/(TEXT($B$4:$B$11,"mmyy")=TEXT(E6,"mmyy")),$C$4:$C$11)

Setting up the Data

• We will set up data by inputting our Dates (month and year) in Column B and Sales in Column C
• Our result will be returned in Column F by the formula. We intend to know the last SALE VALUE that was added to the table for each month

Note- We have formatted the dates by doing the following. First, we will type the dates in this format into COLUMN B: 1/1/2019. We will highlight the dates from Cell B4 to Cell B11. We will right-click and click on format cells.
