Currently, it is possible to click a cell in Google Sheets and "get a link", however, when this "link" to the cell is inserted in a Google Doc, it hyperlinks to the Google Docs app, and does not show the cell value.
How can I render a Google Sheet Cell's VALUE in a Google Doc?
EDIT: To clarify, let's say I have my favorite number in a cell of a Google Sheet, and I want to have that number referenced in a Google Doc. I want this to look like the first line of the image below. The following lines are what I get if I command-C copy the cells in the Sheet, based on the answer from @doubleunary, which is not as ideal but at least it's closer to what I want!
