Comparing large CSV Files
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 |

Comparing large CSV Files
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. -- Jim "Steve Audus, Chaucer BEC, Sheffield UK" soft.com wrote in message ... | 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 | | |

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

Comparing large CSV 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.
