ELI5: How is it that copying a 1Gb file takes less than a minute, but copying 22,000 lines and 20 columns in MS Excel takes forever and potentially crashes the software?

Can't they make a copy/paste procedure similar to how the hard disk normally copies files? I know that it's Excel and that moving data around inside an application is different from moving it around a hard disk, but why? Nowadays computers have gigabytes of RAM, and multi-core 64-bit processors, and they can even scratch your balls for you, but still it's a real hassle to manipulate large amounts of data in Excel, and probably many other programs.

You can compare it to trying to move a 10 kg box filled with marbles, and 5 kg of marbles without a box. For some reason moving the marbles are easier when they are in a box, even though you are moving more.
