C# SQL Bulk Copy: Column returning "null" halfway

Question

c# excel import null sqlbulkcopy

When I am using SQL Bulk Copy, my columns return "null" halfway through the insert...

The only thing I can think of is because of special characters such as "/" and "-". Is it at all possible to escape chars in SQL bulk Copy?

I've tried looking it up, but no one seems to have to escape chars in SQL, any other solutions?

After import to the database: (All Fields are VarChar(50))

After looking into my excel sheet a little more, I realized that my fields were set to "General" and NOT as "Text".
