The goal of SSFiddle is to make working with spreadsheets as fast and convenient as possible.
I'm' currently actively developing SSFiddle so things can still change and not everything will work well immediately. I hope you understand.
Private fiddles aren't indexed by search engines and they're not searchable through SSFiddle. Only someone with the link can access a private fiddle. Note: public fiddles that later become private may already be indexed by search engines.
