Multiple Products by Month over multiple years

[wiwchar]

Good day,

I have a need to consolidate monthly sales data from multiple years for many products. The sales data is in a spreadsheet for each year. The products sold have had some added and some discontinued over the years, and currently an overall master list does not exist that covers this. The data for each yearly spreadsheet is in the form where the product name is in column A, row 5 is the last day of the month and used as the header for the month, and then the monthly sales fill in the respective cells. I first need to take all this data and create an overall list where I would have the product name in column A, the last day of the month in column B and then the sales for that month in column C. I need this format as then analysis requires multiple scenarios such as yearly changes, yearly peaks, seasonality, and more.

What is the best method to make the consolidated list since the products have changed over the last 10 years.

Thanks in advance for your assistance.
