Grid coordinates to alphabet x & y position

Job ID: 33221206

Budget: £10 – £20 GBP

I have a typescript project where the user is given coordinates.

For an example x = 0 & y=0 this alphabet position is the center of O14 and each grid size is 150.
Another example x=76 & y=0 this position would be P14.

So what I am looking for is a function to calculate which grid the coordinates align to
