I need your ideas and help on a topic. In my C drive, I have files in the folder called Personnel with 4000 extension files with an ID number. If I write the personnel registration numbers in column A of the worksheet in Excel, the identity numbers in column B will be opposite the identification numbers. I wonder if it is possible to print as a header to the relevant PDF extension files in the folder where I have specified these registry numbers with the macro. I will use this macro when making staff files and it will make my job very easy. Note: It will not change the name of the PDF file, it will only print headers on the contents of the PDF file.
