Usually, in a spreadsheet, you’ll have one line of text, one piece of information per cell. Whatever the data may be – an amount, a date, anything really. In some instances that may not be the case though; you may find yourself wanting to keep an entire address in a field, for example, or a few sentences of a description.
Thankfully, you can – to type information into more than one line in a Google Sheets cell, click on the cell in question and type the first line of your content in.
Then, press Alt + Enter on your keyboard (or Option + Enter if you use a Mac) to get to a new line. Type your info into the second line as well and either use Alt + Enter again or click somewhere else to go to a different cell!

The info will expand your cell to the necessary size unless you manually set it to be smaller. If so, you can still double-click on the cell in order to see everything in it.

Rob says
Oh wait! Yes, it does. I was pressing Shift instead of Alt. Haha!
Rob says
NO, this doesn’t work!
