Random lines appeared (how to delete)

[Marvo]

Hi. I've had these boxes with numbers and lines suddenly appear in a workbook. I don't know what they are and I can't seem able to get rid of them. Any ideas? Thank you.

Try with shortcut

ALT+ A + ZO + U + C

Data -> Outline -> Ungroup -> Clear Outline

That's done it. Thank you. No idea how they came about in the first place, must have pressed something accidentally.
