It's not dead at all -
but there are some dead areas at the tips of the leaves, and what looks like one completely dead leaf.
Trim off the dead areas and the dead leaf,but don't prune.
These plants grow from the centre, and if you're in the northern hemisphere, it will now rest and not do very much.
Even indoors, though, it needs as much as sun as it can get, but should not be anywhere near a heat source like a radiator or fire.
As far as watering goes, only water when the surface of the potting soil feels dry to the touch, and water well, emptying away any excess water in an outer tray or pot after 30 minutes, never leave it sitting in water.
Further information here, https://www.todayshomeowner.com/how-to-grow-pineapples-as-houseplants/ - the bit you're interested in is towards the end.
You'll note the size of pot required, and the fact that these plants benefit from being outdoors during summer.
I'm rather curious as to the cause of the white lines or what look like scratch marks on some of the central leaves...

I by far am not an expert, this is more of an opinion than advice.
I would prune it back, chop off all the dead.
My Aunt says dead leaves sucke the life out of a healthy plant.
Maybe do a quick Google search of what type of fertilizer would be good for it, to give it a boost.
Good luck.

Update.
Here is what it looks like now.
It helps that I now keep it outside in a warmer climate.

The pineapple has recently started growing!

The yellowing is from over watering or pests.
I cut my plant back because it got severely over water from the hurricane rains we got here in Va.
I'm going to check the roots for rot and depot mine.
Finger crossed!!!

I planted a pineapple plant. Some leaves died. Tips of others died too. But, as you can see in the picture, most of it is green. It has been this way for months, and no new leaves grow. Is it dead? If not, what should I do to encourage growth?
Is this pineapple plant dead?
