Merging workbooks in Excel

I'm about to start a huge project.  I need to clean up our data from 2006-2011.  I have 5 years of weekly spreadsheets with a dump of employee data.

I'm attaching 4 workbooks.  
1) Is there a way to combine the books
2) Can an audit be performed and any data changed displayed? (from any column).  
(for example 3552 went from status Active Pending (8/31) to Active (9/6).

EMPLOYEE is the key

I merge about 300 workbooks.  Is Excel the best way to go with this?

In the 5 years, the worksheets have grown (add more data columna), data columns has changed position in the file, column titles have changed.

I thought about Access.

Is there a more powerful tool that can handle this.
8-31-2011--merge-.xls
9-6-2011--Merge-.xls
8-15-2011--merge-.xls
8-23-2011--merge-.xls

yes this can be done.
* i will use access to import all workbooks to an access table.
* after the importation, you can run queries
   * to eliminate duplicate information
   * update information
   

* you may need a mapping table to handle the change of column titles.

Could you please demostrate this from the 4 files that I attached.  I'm not as familiar with Access, but once this is started I can replicate it for my project.

Hi there,

I create a Demo Database, which will import your XLS files at your give path, with or without subdirectories. It will then append the Records to tblNoDuplicates, which will contain no Dups of Employee.

MergeXLS-v0203.zip

It will work only when all your XLS files have the same columns and the same format, if it differs it will be more complicated to Automate this.

If you have any questions let me know.

Hope this is what you after.

Cheers,
Daniel

NOTE: I need more info in regards to the criteria of EMP_STATUS. So I can modify the Demo to your needs.

If you need all EMPLOYEE <> "Term" ... then here is the modified Demo:

 MergeXLS-v0203-v2.zip

This demonstration was exactly what I needed.  I can tailor my workbooks to contain the same columns and then I'll use this demo to perform the import
