Hi, I could use some help comparing two Excel spreadsheets.  The purpose it to keep up on my college's ever-changing class schedule.  

The columns will always be the same.  Rows can be added and data in existing rows can be changed.

Example:  I would start with File 1 and add some columns at the end with my own notes.
The following week I would receive File 2 containing changes and additions.  

I want to get those changes/additions into File 1 so I can maintain my notes but have the most current information.

"Class" is the column that should be used to match on.    

Highlighting the changes made would be good too.

1. What do you want to do about the prior changes?  For example, if you have changes noted/highlighted in your notes worksheet and you import the new version of the schedule, then how are the prior changes' highlights supposed to be treated?

2. Do you have to keep your notes in the same worksheet as the schedule data?

3. How do you use this change data?

To simplify the problem at hand, let's skip the whole issue of highlighting what gets changed.  If I could just get the changed data incorporated into my original document that would be awesome.

That is why I asked you about the location of your notes.  The simplest solution would be to replace sheet1 with the latest copy and keep your notes in sheet2 with the key (class value) being use to get at the current version of the course data.

What a great (an obvious!) solution!  Could you help me with an example, assuming my notes would be in 4 or 5 columns to the right of the data.  Thanks!!!

Please post your current notes workbook.

I'm leaving town for the weekend and may not be able to look at this until Sunday.  In the mean time, another expert may post a solution.

It would be helpful if you let us know how you used this, providing us with the context in which to offer you solution(s).

After pondering my question, I think I'll be able to do a simple vlookup based on the unique class number column.

I appreciate your assistance, and I think I'll call this one "answered"!

A terrific, non-technical answer based on a new set of eyes on my problem.
