How to output data from Google Sheets to a Chrome extension?

Question

Google Chrome

Essence of the question:
There is a table (Google Sheets) It has about 20 values ​​of interest. The document is weighty and it is not advisable to apply for the information you need from it every time. There was an idea to sketch a simple extension for the browser, where the necessary information from 10-20 cells (numerical values) would be displayed in a column.
What is the easiest way to implement this and is it possible to implement it with Google Sheets?
I know basic CSS HTML JavaScripts and some other little things. I ask for help in which direction to dig and where to start studying to work with this issue
