What installs the JET ODBC Driver?

I know that Excel is not a multi user app and one should not attempt to use it in a multi user web environment, but is using the JET Driver to read Excel files OK?

What installs the Jet Driver? My guess is that you 开发者_如何学Cget it when you install ACES or EXCEL or some other Office apps and that I wouldn't normally expect it to be found on a web server. Is this correct?

If it can be installed separately, is using this driver to read an uploaded Excel file a viable approach provided that the XLS file will only be read once when the file is uploaded into a table?

Here's a very good C# project for reading Excel files in purely managed code with no dependencies and is safe for use in ASP.NET.

If you have significant existing code and want to stick with Jet, you can download an installer here. Yes, it is safe for use in ASP.NET (Office automation isn't, but Jet is fine).
