Creating an excel sheet using pdf file

Hi all ,

I am a show organiser and have attached a pdf of the seating allocations of my next show:

I am hoping to create an excel spreadsheet, where each individual cell in the spreadsheet is a seat. I would like for the excel spreadsheet to look exactly how it does in the pdf (so when I zoom out of the pdf to see the whole venue, the seating arrangement follows the true shape as seen in the pdf)

FYI: It is terribly difficult to explain why this is needed but rest assured it is!

Please advise on the best and quickest way possible to do this!

Thanks in advance!!
