A file that works as is:

phone,name,city,customer_id
+919999999999,Asha Sharma,Mumbai,CUST-10241
+919888888888,Rahul Verma,Delhi,CUST-10278

phone is the only required column. name, city and customer_id become the variables {{name}}, {{city}} and {{customer_id}}. Google Sheets must be shared as “Anyone with the link”.
