Woah everything with a simple excel file, that's impressive :O

Nice work !

I'm curious about how you are getting data to flatten recipes and create lists, could you elaborate a bit about that?

That being said, paying for hosting is not that difficult, as a lot of hosting providers will cost you less than $30 a month, one dollar from 30 people is not a lot of money to ask for, to provide them a tool that will allow them to gain a lot of time.

Your work is impressive, props for doing that with a simple excel sheet
