如何自动将数据发送到Excel

I've been doing some research on how to have sql server create invoices or reports automatically given a specific time, similar to a scheduled job. I want to be able to use an excel sheet which has the invoice template and update my sql server update the fields with the given data (Customer Name, account Id, sales tax, etc). I came across SSRS which does reports, but I dont know if that will do data processing for me. The type of processing I need is simple, gallons used * price/gallon * sales tax. I have very little experience with sql server, from what I know, its not very convenient to these algorithms in sql so I rather have excel do it for me. So again, is there a way to have sql run an automated query that updates an excel spread sheet? I have imported data to excel via csv file and vice versa, but the thing that is confusing me in this case is that my excel spreadsheet itself is an invoice template with a company logo so I can't just import data to the template. Does anyone have any suggestions? Thanks.I've been doing some research on how to have sq
