title: Google Sheets Script: Search For Any Cell With Error
body: <p>In a spreadsheet I use almost 2M cells, which use a lot of functions, including ArrayFormulas etc spanning thousands of rows. Many columns do calcs based on previous columns that are also calc'd, so errors cascade.</p>
  <p>Is there a way to do something like using createTextFinder(), but comparing a cell's contents to an array of ERROR.TYPEs?</p>
  <p>Or is there no smarter way other than looping through all the cells? Although I can accomplish that, I'm sure there's a more efficient way to go about it.</p>
