Updating csv data on my php website

Dear all, I have a stock csv file to upload on my website and refresh data. Earlier i had a software where i would create my csv file via MS Access and click on the software icon, it will ask for option to upload - once clicked it will refresh the data on the website. As i have a shop, the data stock levels change and new stock is added on a daily basis, this needs to be populated on a daily basis. I am looking for a website based 'button' which would process and populate my stock data OR a desktop application which will push data to the website. Just for an idea - the website is [[login to view URL]][1], i am also attaching the a sample file - to give you an idea as to what fields and data needs to go up. thanks ml
