First time trying to create a datapack - I'm confused

Feel like I'm so close yet so far Log keeps giving me this text - Couldn't parse data file 'craftables:crafting_recipe' from 'craftables:recipe/crafting_recipe.json': DataResult.Error['Invalid pattern: too many columns, 3 is maximum; Map entry 'x' : Failed to parse either. First: Not a string: {"item":"minecraft:iron_ingot"}; Second: Failed to parse either. First: Not a json array: {"item":"minecraft:iron_ingot"}; Second: Not a string: {"item":"minecraft:iron_ingot"}']
