Update Customer Contacts in Google Sheet

Job ID: 39934026

Budget: ₹100 – ₹400 INR

I need help keeping a single Google Sheet up-to-date with my latest customer information. You will receive one clean CSV file, and from that file I want you to:

• add any new contacts that are not already listed,
• modify existing rows when the same customer’s Name, Email Address, or Phone Number has changed, and
• remove contacts that no longer appear in the CSV.

The sheet already exists—just open it, carry out those three actions, and return it to me in its updated state. No scripts or extra automation are necessary; a careful, manual pass is all that’s required. Accuracy is more important than speed, so please double-check for duplicates and obvious typos before you’re done.
