account_type column values read as real number by your process. to correct this right click on the excel source and choose show advanced editor. There navigate to the Input Output Columns tab the one most right. Expand the output columns and locate the account_type column then change its data type four byte integer (DT_I4)
then run your script.

Add a Data conversion task or Derived Column and change the data type of the column. use this column in the destination mapping. add it as a New Column in Derived Column and  you use the below expression. The column Names are Case sensitive so, check the column Name

(DT_I4)(account_type)

If you are trying to learn, I would suggest you use Import/Export Wizard in Sql server and do all the changes required and then at the end check the box and save it as SSIS package.. You can later, open it using visual studio and see the Design

Hope this helps !!
