I can think of two ways to do this:
- You can create a form in google spreadsheets. The form appears as an html document with standard tags. From here, I would use labview's http functionality to submit data to that form using a POST request. This would be the easiest way to get data in there.
- Using the Google Apps API, you can manipulate google spreadsheets and dump data in there directly. This is going to be more complicated in terms of development time, but more configurable in the long run. https://developers.google.com/google-apps/spreadsheets/#what_can_this_api_do There are .net and java code examples throughout the documentation, so it would take some work to port this to LabVIEW, but it could be done.
