google docs api word count
function countWords() {
var s = DocumentApp.getActiveDocument().getBody().getText();
//this function kept returning "1" when the doc was blank
//so this is how I stopped having it return 1.
if (s.length === 0)
return 0;
//A simple \n replacement didn't work, neither did \s not sure why
s = s.replace(/\r\n|\r|\n/g, " ");
//In cases where you have "...last word.First word..."
//it doesn't count the two words around the period.
//so I replace all punctuation with a space
var punctuationless = s.replace(/[.,\/#!$%\^&\*;:{}=\-_`~()"?“”]/g," ");
//Finally, trim it down to single spaces (not sure this even matters)
var finalString = punctuationless.replace(/\s{2,}/g," ");
//Actually count it
var count = finalString.trim().split(/\s+/).length;
return count;
