Connections always require either a source or destination sheet. Hence you need to tell Sheetgo to which spreadsheet it should connect to. For this, we provide a search function that searches your entire drive for spreadsheets.
By default, our search algorithm shows you a list of your most important spreadsheets.
If your desired spreadsheet is not among those, use the search input field at the top to search for the name of the spreadsheet that contains the sheet that you wish to connect to.
