You need to profile your code to find out where the bottleneck is before you can start fixing it. Just dumping 669 lines of unexplained code in a message and expecting us to profile it for you isn't going to work - especially since we don't have access to your database. And since you can't be bothered to remove irrelevant code, such as the unused DelayMSC function, you clearly don't care about helping us to help you.

For a start, look at your queries. If your outer query returns 2000 rows, you will be executing 2001 queries to load the data, since you execute a separate query for every row in the "header data" query. There will almost certainly be a way to combine the queries so that you only need to execute one.

You have multiple calls to the Delay function, which will delay your code by more than 10ms each time you call it.

You're calling Application.DoEvents, which is always a code-smell. It indicates that you're doing work on the UI thread which should actually be performed on a background thread using a BackgroundWorker[^] or similar.

Also, Office Interop can be quite slow. You might have better luck using the Open XML SDK[^] to generate the file instead.
