Crossword Template Builder + Auto-Fill

Choose or edit a template, load a word list, then auto-populate the grid. If a slot cannot be filled, edit the black/white squares and run auto-fill again.
Build Sheet

Pattern uses # for black squares and . for usable letter squares. Click any square in the grid to toggle black/white.
