SeatSolver is a free seating chart maker for weddings, events and classrooms that works from the guest list you already have. Drop in an .xlsx or .csv, or paste from Google Sheets, with your own column names, plus-ones and a "do not seat with" column. It shows which column it read as what, so you can check its reading before anything is solved. Name the pairs who must or cannot sit together and get a table plan that holds every rule; couples and households are placed as blocks. When guests drop out after you printed place cards, it re-solves while keeping the rest of the room almost as it was, and names who moved. Export a seating chart, place cards, escort list, table signs and a floor plan as PDF, plus CSV. No account, no guest limit, and your list never leaves your browser.
