Posting data into Google Spreadsheets

I have created the scraping session and data extract but now need to post it into a Web Form page. ( I looked at the Tutorials but did not see the Shopping site post the data to the form)

I thought why not try one of the free sites like GoogleSheets or Zoho where you can create a form or post to a URL for online storage.

My question is --- Once I have the data extracted into variables I know how to store it in a file but using a script or scraping session how do I post it to a URL?

Thanks
