Excel

The best component I've found so far is called EPPlus . His NuGet package is here . Here on the site we have some questions answered about it . I recommend reading them for examples of implementation examples.

PDF

It's common to use Rotating because it accepts HTML as input and returns a PDF, but the Revolve does not work in purely Web environments like the Azure.

Looking for alternatives, I found RazorPDF , but the package has not been updated for some time (I think the author has died or something like that, because it does not respond to my messages or that of other users), so I created the RazorPDF2 that works with all the features of RazorPDF and join some more of this one .

Datatables

Still within the scope of export, Datatables (jQuery-based component) has options for export to PDF and Excel based on Flash. It can be an option if your system does not make much use of interfaces with mobile devices. The documentation is here .

Needing more details to use, just ask new questions.

I've already used Telerik Reporting , are great components, have export to excel and pdf native and not you need to implement anything for this to work. However ... it is paid ...
