Hi. I have an Excel file with many worksheets. Each worksheet represents an
account, and each row represents an invoice. I email the file to someone who
updates values in a couple of the columns (like Date and Comments) in
multiple worksheets. She returns it, but in the meantime, I've added invoice
rows to some of the worksheets in the original file. I would like to update
the original with only the changes that she made. Is there a relatively
simple way to do this?

Thank you,
Ryan
