I think this is possible, but just wanted to get some feedback and/or information/links.
Theoretically, I would like to have the ability to upload and Excel file to a web page (say ASP.NET) and have this collection of data validated against an existing web service I have in place . This web service is used to CRUD operations into the DB and has a bunch of validation rules. I would like to bump this Excel file before submitting it to the DB to be validated against my rules that exist in the web service.
