It'd be easier with three hands or a tool. A tool with a short pusher rod and two tweezer-like arms for the spring tabs could probably be designed and fabricated to make it more-or-less a breeze, but none exists that I'm aware of, because it's not all that hard once you get the hang of it.
The procedure linked above is how I learned to do it, though - the kicker is that the spring baseplate (lockplate, in official nomenclature) that must be pushed up out of the way of the spring tabs in order to free them to be pushed in, in order to remove the magazine floorplate. The tabs won't move until that lockplate is pushed out of the way from below, and the floorplate won't come out until both those spring tabs are pressed in and disengaged. It doesn't help that floorplates typically fit very snugly, so it can be a little hard to remove them even with both tabs disengaged.
