Comparing large CSV Files

[Steve Audus, Chaucer BEC, Sheffield UK]

We generate a csv file each night with over 10,000 records,
it's a list of classes, teachers and students.

Could anyone give me some advise on a easy way of automaticaly comparing the
one csv to another, and then creating a 3rd csv with just the differences?

Thank you for any help or advise.

Steve

Since you're asking in an Excel group I guess you're thinking of using Excel
for this. But this is no specific tool in Excel that does this although you
could write a macro for it. I'd so an internet search on "compare text
files" and I imagine you'd get a lot of hits.

MSWord has the ability to compare documents--including text files.

Steve,

I think the best way to what you ask is by using MS Access. First you creat
a new database and then link the csv files (File ==> Get External ==> Link
Tables). Access will link to csv files very easily. Then create a query
that queries all 3 csv files. Now, you may have to get additional help from
the Access Users' Group. This approach should solve your problem.
