This file is a PDF file and I convert it to an Excel file.
I would like to link this workbook to another Excel Workbook that contains 4
worksheets, I would like information from the PDF to flow into the Excel
Workbook once I have converted it into an Excel Workbook. Is there a formula
that would do this. Both sheets have the employee's name and both workbooks
will have the number of periods attached to it. But I need the information
from the converted PDF file to flow into this workbook.

This is what the second Excel Workbook that has 4 worksheets attached looks
like
the very first worksheet is almost exactly the same except I would to set
the protection on this worksheet. Is this possible. I have been typing in
all the codes and it takes up a lot of time I have 9 Highschool's to set up
and each Teacher has a number of courses codes for each Semester.
