I was wondering if I can use Aspose.Cells.dll. I downloaded it from the their website.
https://downloads.aspose.com/cells
I'm curious do I just need to add the dll to my project? Can they charge me or my workplace? Is the Dll file that I downloaded just code? Does a free version exsist? Does the DLL connect to the internet? What is a DLL? I'm really confused.
I didn't put in any information just download and created an account on their website? Could I be going against the licensing agreement by adding the dll to Microsoft Visual Studio.
Thanks,
