Look Up Function Recognize The Vendor Code And Assign The Appropriate Name

I can only export vendor codes from the General Ledger rather than vendor names. If possible, I would like for excel to recognize the vendor code and assign the appropriate name. For example, HCC stands for Human Capital Consulting. The GL includes the vendor code and the voucher number. If I export the vendor code HCC/V0007 from the accounting system to cell A2 in excel, I would like for excel to pick up everything before the / (in this case HCC) and enter Human Capital Consulting in cell B2. I have a vendor list in excel that matches vendor code with vendor. I just need for cell B2 to pick up the vendor code from the list.
