Testing functions google in localhost

[claudio fernandes]

Is it possible to test, run google functions, such as google.script.run on my localhost machine to get data from a googlesheets?

if yes, how do you have to do to make it possible?

This channel (https://www.youtube.com/@get__itdone7958) has a lot of great videos. These specifically may help your situation. 
Bottom line, yes, you can do it. These use node on the local host:

1)  Develop Google Apps Script Locally in VSCode using CLASP

2)  CLASP Web App, Google Apps Script, Parcel JS, Nodemon, Node JS Workflow Setup Tutorial

3)  Apps Script Web App - Passing Complex Data between Server & Front-end

 Good luck!
