I've seen people mention Plan to Eat (plantoeat.com) in connection with EYB elsewhere on the forum, but always as an either/or situation. I'd like to be able to bulk-export data from EYB so that I can include my book recipes in the planner/shopping functions in PTE. I don't know if that would mean an html or excel export, an API, or something entirely different, but I wish the two websites I use most could talk to each other somehow! At the least I'd like to get the book title, author, and recipe title - even better to get the ingredient list.
Import options on PTE are html, json, and csv, among others.
I've used the PTE bookmarklet for individual EYB recipe pages, but it takes FOREVER to get through a book by tagging each individual recipe with the book it comes from!
