New Horizons:Spreadsheet
From Animal Crossing Mods Wiki
The Animal Crossing: New Horizons game consists of many different items, villagers, achievements, recipes, and more. Over the last several iterations of the game, communities have developed around building spreadsheets to track all of this data. Every item includes information about its cost (buy, sell), color variations, what size they are (1x1, 1x2, etc.), Happy Home Academy information, etc.
