Merge Multiple Worksheets Into 1 Based On Common Field

I have multiple worksheets with multiple varying columns with varying rows. My one constant is the product_id. I want to merge all worksheets into 1 worksheet based on the product_id's. Here is my example:...............

It has to consolidate all of the column names from all of the worksheets into the final worksheet, then take all of the rows and put the product_id in the product_id column and put the other data under the appropriate columns. Some columns will end up blank where they may be a column in worksheet 2 but not worksheet 1.
