The List View option provides a minimalistic view of your spreadsheet data. It's particularly useful for those that have viewing rights only, but have a great amount of data to manage. If you're trying to access a spreadsheet with more than 50 users currently viewing it, you'll be automatically redirected to list view.
List View allows you to:
View spreadsheets on a slow Internet connection.
View spreadsheets from mobile phones with webkit-based browsers (iPhone, Android, Nokia S60, Palm Pre), Opera Mobile, or Opera Mini.
Get a simple view of your data with or without formatting.
Sort and filter data without modifying it.
Enter data in a simple way.
Share a read-only spreadsheet, but allow sorting and filtering.
Things you can’t do in List View are:
Add new collaborators and viewers
Insert images, charts and gadgets
To access List View go to the View menu in your spreadsheet and select List.
