title: Possible to use Google Spreadsheet functions in Google App Script?
body: <p>I just discovered Google App Scripts, and I'm stumped on something already... </p>
  
  <p>I am trying to write a script for a Google Spreadsheet which finds certain historical stock prices. I found that the FinanceApp service within Google App Scripts has been deprecated, and seemingly replaced by the GOOGLEFINANCE() function within Google Spreadsheets. However, it returns an array, when I need only a single cell, and the array is mucking up the works. </p>
  
  <p>So I'd like to write a short script that calls the GOOGLEFINANCE() spreadsheet function, and finds just the 1 piece of info I need from the array which is returned by GOOGLEFINANCE(). However, I cannot find a way to access Spreadsheet Functions (SUM, VLOOKUP, GOOGLEFINANCE, etc) within a script. </p>
  
  <p>Is there a way to access these functions in a script? Or perhaps, is there a new service which replaces the deprecated FinanceApp service?</p>
  
  <p>Many thanks for any assistance!</p>
