Get Spreadsheet Rows

You don't need inputs for this automation.

It will fetch data from a spreadsheet, based on a header (the first row).

• Google Sheet Spreadsheet Id - the spreadsheetId in your URL https://docs.google.com/spreadsheets/d/THIS_ID 
  You need to extract THIS_ID from the URL in order for it to work.
  
  
• Sheet Name - the sheet name to use; cannot be empty.

Remember that you need to use headers in your spreadsheet.
