Can I insert multiple blank rows on an excel sheet?

Yes. Highlight a cell, then drag it down (highlighting) for the needed number of rows. Then select insert rows. It will insert the number of rows highlighted.

Go to the left column (the preset column with all the row numbers, before Column A).

Left-click on the row where’d you’d like to insert.

Drag your cursor down for as many rows as you’d like to add. Don’t worry about highlighting rows that already contain data; those rows won’t be affected.

Insert, either by right-clicking or by going to Home/Insert.

The new rows will appear above where you’d originally placed your cursor (the top of the highlighted rows).

FWIW, I am a huge fan of hot keys. Do what they said, but instead of “selecting” insert, just hold down the Alt key, then hit the letter i then r.

I would probably just go with redo. Do the action you want repeated and then tap CTRL – Y until you have enough lines inserted. Admittedly it’s a very sloppy way of doing it and purists could probably give you a dozen reasons why you shouldnt do it that way. But it works and it’s fast. Ish.

New hot key! Thanks @Lightlyseared! Running off to practice

What other things would that be useful for?

Well, you can if the worksheet is unprotected…

F4 is also a redo key. Paste the new line then hit F4 as many times as it takes. I use F4 a lot for many different repeated actions.

Do you ever hit random key strokes just to see what will happen @Stinley?

Of course. I’m queen of “what does this button do?” Ctrl- Z is my friend!

I know exactly what you mean! All hail Ctrl Z!

When I was teaching at the jail, the first thing new students had to do was write a little autobiography. At some point I’d go up to them, ctrlA to highlight the whole document then hit some random key. Of course everything they’d done was GONE! It was shocking!
I’d say, “Now I’m going to teach one of the most important keys there is.”
CtrlZ…and it’s back!
