Hope someone has a formula to remove a dark stain from wood floor. It sort of looks like ink but I know its not that,however, I have no idea what happened or how to deal with it.

RE: Need help. Black stain on wood floor.

old wood floor (one that's varnished or oiled), new wood floor (one that's poly-treated)?
old stain? or a recent addition? any texture at all?

in general, I usually try the following in order:
'magic eraser' type sponge (use damp, rub gently)
baking soda paste )can rub vigorously)
'goo gone'
automotive 'polishing' compound, applied gently with a rag - this is a stronger abrasive than the magic erasers, but will not appreciably mar the floor's finish.

by this point, you will have a better idea if it's a surface stain, or something that has soaked in to the grain of the wood itself - which is the worst case scenario, since anything that will lighten the stain will also lighten the surrounding wood, making sanding or chemical bleaching tricky.
