Hi,
I can do this work for you.
My questions to you are:
1. On an average, how many rows will be there in these 30 sheets?
2. You have mentioned that "Many of the items on the list you'll skip. Only relate to the ones in bold. Skip anything with a sales rank above 50,000." But, in the sheet you have attached, from row 8 to row 15, the Ranks of all of the is above 50,000, then why are these in Bold?
Best,
Sanjay.
