FileHelpers VS AutoMapper

Not a public repo, but it’s used this way in a production environment for the last few years when loading fixed length files from a few different state agencies (we process using C#, and the Files Helper NuGet package, see www.filehelpers.net for some code examples).

Try this https://www.nuget.org/packages/FileHelpers

I’ve used https://www.filehelpers.net/ for a long time.
