I have a few merged cells in an excel file in Microsoft Excel Online in the browser.

I want to use javascript to auto resize the height of the cells based on how many words are in there. Sometimes its just a few words, but other times its multiple paragraphs.

I used to have this in a VBA macro, and the code was simply:

Rows("4:4").EntireRow.AutoFit

Can anyone tell me how to do the same in Microsoft Excel online in the browser?
