[Grist founder here] On separating formulas from data, that's always been an important part of Grist.
In Grist, check out the "Code View" page in the left-side panel -- it shows all the logic (i.e. formulas) of the document along with the Python data model (i.e. all the column names and types).
Also, you can save or download a copy of the document without the data, but keeping all the formulas. So you can get all the logic (and formatting, layouts, etc), and use it for different data.
(No support for solving circular references though.)
