If you know you are going to collaborate on a sheet before you start work on the sheet, you can create it from scratch in Google Sheets. Once you have created a new sheet, you can add content and name the sheet as required.
To create a new sheet in Google Drive:
Ensure you are signed into Google Drive
Click on the New button on the left-hand side of the screen
Choose Google Sheets
To create a new sheet from within an open sheet:
Click on the File menu
Choose New
Choose Spreadsheet
The new sheet will open in a new tab or browser window, depending on your browser.
Once you've created your sheet, and before you start adding data, it’s good practice to set a name for the file, so that it isn’t saved as "Untitled" or the text you enter into the first cell of the spreadsheet.
