Most apps provide some method of being able to export your recipes. CookBook supports most industry standard file types so if they do export files (other than their own proprietary files) then we might be able to import them.
The more descriptive recipe formats are JSON-LD, Microformat's hRecipe and Schema.org's Recipe. If you put either of these in a text file, CookBook will be able to read the content of the data.
Single Imports:
Within the app you'd just need to hit 'Add recipe' then 'From a file' and you'll be able to select the file from your file manager on your phone.
Bulk Imports:
We support bulk importing from a number of different recipe managers, check out our article here to see the full list.
