Fetching Data from Google Sheets
One of the easiest ways to get custom data into Dash is from a Google Sheets spreadsheet on Google Drive. You can import an Excel file or build your spreadsheet right on the site. They even have great collaborative editing so other people can update the widget data if you want.
Just enter the data you want displayed in the right format for your widget.
Then choose your google drive spreadsheet from the dropdown in a google drive widget.
It's that simple!
