I have a request to put a large Excel dataset on a MOSS 2007 sharepoint page. The XLSX is about 13 MB in values alone - about 50,000 rows. It's updated weekly, usually in batch form (i.e. some hundreds of records changed).
I am hosting it through Excel Web Services.
What's the best way to keep my users from being able to download the entire file? I know I can restrict their view of it, but how do I stop them from accessing the source library?
