将php web信息保存到Excel电子表格中

Ok we have this prefilled excel spreadsheet that we just update our name, mileage, and location on once a month. The spreadsheet calculates our millage with the built in formulas. What I would like to do is have this page on our website. I would pull from a sql database depending on the options you select prefill my labels on the web and save it to the correct spot on the excel spreadsheet once submitted. Sounds easy in theory but I'm not sure how to go about doing this or if it is even possible? Can someone help me out or get me started in the right direction. Thanks

Take a look at PHPExcel. It allows you to read and write Excel documents (and PDFs, and OpenOffice.org Calc documents and more).
