A few tools I've used that could be helpful for automating building are below:

Draw.io
Web-based platform that will allow you to map/diagram your processes.

JavaScript Methods
Useful list for Fields: Field formulas action, as well as Tables: Apply formulas to columns, and CSV: Apply formulas to columns.

Repl.it
Useful for JavaScript formula syntax checks, using Fields: Field formulas action, as well as Tables: Apply formulas to columns, and CSV: Apply formulas to columns.

RegEx Pal
Useful for checking regular expressions, for e.g. field validation, or formulas.

CSS Selector Reference
Useful for Browser: suite of actions, when defining your own CSS selectors for a browser automation.

CSS Combinators
Useful for combining CSS selectors in Browser: suite of actions.

JSON Validator
If constructing JSON with a sequence of steps for a Web API: action, it can be useful to run a syntax check on your schema.

There are also a few browser extensions available on the web that allow you to copy CSS selectors for objects on a page.
