I am using a spreadsheet with 4 sheets, but 2 of the sheets have suddenly appeared with over 1 million rows, which is stopping me from inserting new lines in the middle of my data. I am only using around 200 rows on each of these 2 pages.
So, how can I delete these extra rows quickly, without having to select each row and right click and select delete?
I'm not very savvy with excel so please reply in very simple language!
Many thanks in advance.
