In the SSIS Data Flow you would use a Flat File Source. Configure the sources connection manager to use the "Ragged right" format and mark where the columns should be delimited, including the appropriate row delimiter. In the Advanced options change the properties for each column, such as Column name, data type and width. Then connect that to your destination.
If the fields won't be in the same position and same width the above won't work. For that you could still use a Flat File Source and read each row to a single column, then split that row up within a Script Component.
