title: Searching for function usage in Excel VBA
body: <p>I have inherited an Excel spreadsheet with many VBA functions and it's not clear where (or even if) a lot of them are being used. </p>
  
  <p>Is there a way to find the usage of a VBA function, or perhaps search for invocations of it, similar to the way you can click on a function/method in a standard IDE and find its usage throughout the codebase?  I am looking for the <strong>cells</strong> from which the functions could be being called, not invocations from within other VBA functions.</p>
