Hi - I am trying to have my spreadsheet either replace numbers with a
corresponding name, or, if it's easier, add a column with a name. That is, I
have the following data:

123
345
357

I want my spreadsheet to either:
1. Replace 123 with Bob, and replace 345 with Jane, and replace 357 with
David. The result would be
Bob
Jane
David

Or

2. Add in a column so that the result is -
123 Bob
345 Jane
357 David

Is there a way for me to do either of these"

Thanks
