Hi all, I have 8500ish records and need to export them to csv in order to compare the data with a master list. Some data will be wrong and will be changed by the batch process run on it. I then need to be able to import these corrections back into the database. How to do it is beating me. Can anyone help? The choices I can see are: 1. delete all current records and import the spreadsheet back in. A dangerous option. 2. find some way for aMember to compare the membership numbers in the database with those in the spreadsheet and overwrite the data. Elegant, but I don't know where to start. 3. do it manually. As I can't tell what will change this means comparing 8500 separate records. Not an option. There is no option to not do this unfortuately, the changes are vital. Pleased for any feedback Matthew
