I have an Excel sheet with keys and contact data.

Some records are top-level contacts with multiple records below that have the same linking key. Like this:

Key | Contact Field
A6010438290&O/S@4Sta | Stacy L
A9010955941(QM*G4Ang | Angie T
A9010955941(QM*G4Ang | Ayca C
A9010955941(QM*G4Ang | Sue L
A2050652317(5XR[ICan | Karin M

I'd ultimately like just 3 records with 2 fields:

Contact Field | Secondary Contacts field
Stacy L |
Angie T | Ayca C; Brad M; Sue L
Karin M |

Any ideas on how I could do this? Or is the solution better found over in Access?
