I have 1 workbook with sheet1 named Found containing column headings of phone
number, First Name, Last Name, ID , Building, Floor, etc. Sheet2 is named
Not Found
This Found will have a list of phone numbers populated already.

I am recieving multiple spreadsheets with the same column headings from the
different groups. These will have anywhere from 1 row to hundreds of rows
populated. I need to run the macro in the Found workbook that will look at
whatever the active workbook sheet1 is open (received from the groups),
compare the phone numbers (sorted in ascending order)in Column A and if there
is a match paste the data from specific column to the correct column in the
row that is the match.
Preferably with error checking - if any of the cells are already populated
insert a row below the match and paste the data (in diferent color) on that
row including the duplicate number in column A.
If the number in column A exists in one of the group spreadsheets but does
not exist in the Found spread sheet insert a row (at the correct sorted spot)
and copy the data including the phone number.
If the column labeled Cost Center is not populated then paste the cells to
the worksheet Not Found
I have thousands of numbers and about 100 spreadsheets to consolidate.
Lastly can I make this macro run from a toolbar button that shows when the
Found workbook is opened and goes away when it is closed.
