You will use Google Sheets to create spreadsheet documents - a bit like Microsoft Excel.
To create a new Google Sheet- Go to Google Drive and click the plus sign at the bottom right hand corner.
A window appears choose Google Sheets
A document appears - Give your spreadsheet a meaningful name (this will ensure you can find it easily at a later date).
A spreadsheet appears for you to start creating. This spreadsheet is saved automatically. The tool bar looks very much like Microsoft Excel and has the same functionality.
This spreadsheet will be saved in your Google Drive.
