Makes setting up feeds very easy - there's a bit of syntax to learn if you want to get lots of detail in there (start with a single quote in the expression editor and it drops all the options down for you) but following a big site migration from a custom setup to Shopify I was able to get product feeds for Google Merchant Centre, Meta and Klaviyo up and running in literally minutes. Probably half an hour all told for five feeds.

Getting some very useful 404 data out of this app to help with a site migration, and very helpful and immediate support from the developer. Recommended.
