.csv with formula, so that my customer can edit that .csv file
I'm going to use PHPExcel https://github.com/PHPOffice/PHPExcel as a library to do the export. I'm familiar in using this library with plain PHP and some other PHP frameworks, but not in Magento.
What I want to know is which module that I need to override (or create new one) to implement my export function? (I know that Magento has import/export function, but it only keep the data, not the formula of
And because Magento has some more new concepts like Block, Template, Layouts... I don't know where to start. Any suggestions?
Thank you very much!
