Macro to move column header dates to row for each unique item

[noxvoortella]

Hey folks! I have columns of sales data (text), and then dates across columns as well. I want to take those dates and format them into one row so each date matches up to each row of text data. Below is a sample of some of the data, but I have 171 rows would like reformatted and dates from 8/5/2017- 8/5/2018.
