I appreciate your response. Structurally your solution is more beautiful, but mine is 2x faster. I have 850 records, and my solution inserts them in 15 sec, whereas the proposed solution is around 33 sec. Speed is very important here, as there will be around 1500 - 2000 records on a monthly basis, and we will use an Azure SQL database to store the data, so updates are a bit slow.
Thank you for your suggestion anyway, it's great way to learn and try.

850 records in 15 seconds is still really, really slow :)

Are your inserts complicated so that you need a stored procedure?

With a proper bulk insert you could do all of that in less than a second.

Yes, I checked your suggestion with the proper SQL bulk insert. It now works, indeed around 1 second. I needed to convert the List to Datatable using the suggested method. Thank you! :)

There you go, way better than initial way you had it. Also tons of times faster.
