phanikr, Good afternoon.
The VLOOKUP function is very good for this job.
Put the function in spreadsheet 1 and search the same name on the worksheet 2.
The names don't need to be in the same order.
Capture the worksheet phone number 2 and bring to a spreadsheet 1.
Please, tell us if it worked for you.
