You can still use automation, but then you must handle everything, or at least most of it, on the client end. And, to make it all just a bit worse, none of these approaches, even when they work, will impress you with their speed. All in all, if you want to handle legacy Excel files (*.xls) you will have to make some compromises.

Last week, Mark asked me for a bit of help on a project where he had to import *.xls files into NAV 2013, and he hit all of the possible walls provided by the Excel Buffer, .NET Interoperability components for Excel, and automation walls possible.

When I gave Mark my solution, he said: you should blog about this. So, here I am, blogging about a simple way to read data from Excel, any version, lightning fast.
