Most Numbers for iCloud templates contain placeholder text in text boxes or table cells to give you an idea of what a spreadsheet created with this template might look like. The placeholder text also shows you the text styles used in the spreadsheet.
Go to Numbers for iCloud , then sign in to your Apple Account (if necessary).
In your spreadsheet, double-click to place the insertion point inside the text box or table cell, select the placeholder text, then enter your text.
To delete placeholder text, select it, then press Delete.
