which gives you are viewbarButton (here it is hidden in the more-toolbar) to export a Tiddler Text to a google spreadsheet. The button is only shown if you are logged in as the modifier of the tiddler (or just modified or created it).
$:/plugins/OokTech/SubmitForm $:/core/ui/Buttons/UploadMore $:/ExportTiddler

in configuration is that the dataTiddler here is called $:/ExportTiddler and that you also put the URL of the spreadsheet into a field form in that tiddler (and not in the button).
