Cannot get data file to execute on Microsoft SQL Server Management Studio

First time trying to run one of my data files that I ended up cleaning up with a python script. This was how it looked like before and after the script cleaning. The file original has about 1 million lines in it, but for testing I just ran the script for 400 lines.

Here's how a lines look like (can't post another line cause reputation points)

After cleaned:

AccessibleComputing Computer_accessibility

Now i'm trying to run the flat file on Microsoft SQL server management studio 2014, after I import the files this is the error message I get:

"- Executing (Error) Messages Error 0xc02020a1: Data Flow Task 1: Data conversion failed.

I tried numerous things but cannot get it to work. Any help would be great.
