The module is developed by @maaakstiles and I really like it because it’s easy to extend/change to fit your requirements. The basic idea is very easy. It gets data from somewhere (Sitecore/CSV/SQL/MySQL). I played with the SQL part.
I would like to import files from another database and create a media item from it. To make it work I had to do 2 changes.
Make it to deal with byte[]

| using Sitecore.Data.Items; | |
| namespace Sitecore.SharedSource.DataImporter.Providers | |
| { | |
| public class CustomSqlDataMap : Sitecore.SharedSource.DataImporter.Providers.SqlDataMap | |
| { | |
| public CustomSqlDataMap(Database db, string connectionString, Item importItem) | |
| : base(db, connectionString, importItem) | |
| {} | |
| protected override string GetFieldValue(object importRow, string fieldName) | |
| { | |
| var item = importRow as DataRow; | |
| var f = item[fieldName]; | |
| // it was the missing area because the default solution calls the .ToString() | |
| // and if it's byte[] then I get "System.Byte[]" | |
| var bytes = f as byte[]; | |
| if (bytes != null) | |
| { | |
| return Convert.ToBase64String(bytes); | |
| } | |
| return (f != null) ? f.ToString() : string.Empty; | |
| } | |
| } | |
| } |
So now I have the byte array converted to string. This value is passed to the FillField method so now I need to change that to attach this stream to the media item.

Remaining step is create a new template for Field in Sitecore and use it. This video shows how you can do that:
