I am trying to do the following: I have row 1. I have values A1, B1, and C1. A1 contains a few names separated by a comma. I want to split A1 by these names while copying over the values from B1 and C1 into the split columns of A1.

For example, I have this:

(A1              B1      C1)
bob,sam,bill     99      10

I want to have this:

bob              99      10
sam              99      10
bill             99      10

I am also doing this on Google Sheets, I tried using combinations of Split, Join, and Transpose but can't seem to figure it out.

Any help would be appreciated, thanks.
