Mail Merge or just Merge Spreadsheet Data

Hi all and just want to thank everyone in advance for your help.

I have two spreadsheets they contain the following:

1. First Name Last Name Phone Address City State Zip -- About 30,000 entries
2. Is basically a lead sheet I use that contains fields for all of the above.

Is there any way that when I am talking to a customer from spreadsheet 1 to have that information merge into spreadsheet 2?

I can see this question has been somewhat asked in the past but unfortunately I can only follow specific instructions.

Thanks
Mooch

See that's what I initially thought can you do the vlookup on each row?
