How do I create a Client Script that takes data from one field and moves it to other fields?

How do I create a Client Script that takes data from one field and moves it to other fields?

I have a field on a Zoho Form for customers to enter serial numbers to register for extended warranty. They can enter multiple serial numbers into the same field, separated by commas (API: Serial_No_Product_1)

I want to set up a Script that will take the data from this field and separate out the serial numbers into other fields i.e. Serial_No_Product_2, Serial_No_Product_3, etc. removing the commas.

Is this possible?
