VBA seems to be best suited for this task, but if we want formulas - why not (will not be a piece of cake anyway).
I added header row and one dummy column (can be hidden or somewhere out of sight - say column Z etc.)

In K2 (and copied down) formula returning first word:
but as we probably will copy this formula with some excess (too far down) it will be better to ad a condition checking:
and in L2 and copied down:
Or with added returning empty cell if column K is already empty:
