I don't want to have to open each point file to correct the fields so...... 

I went throught the excel spreadsheet and corrected the errors. Now what I want to do is find some way to overwrite that information back to those files updateing the fields with the correct info.  I was told that this cannot be done but I am asking in case it can be accomplished through a third party software or something.  I have backed up my files so I am willing to try anything that might work.

Thanks for any feedback.
