Moving, Copying, and Deleting Cell Contents
The Copy feature allows you to copy selected information from the spreadsheet and temporarily place it on the Clipboard, which is a temporary storage file in your computer's memory. The Paste feature allows you to select any of the collected items on the Clipboard and paste it in a cell of the same or different spreadsheet.
Be careful if you paste copied cell information into cells that already contain data. If you do, the existing data is overwritten.
You can copy information from many different sources—including websites, emails, or other Office applications like Word and PowerPoint—and paste it into an Excel spreadsheet.
