A simple javascript code snippet to scrap emails from a Google Forms Page (View other Responses Page). Just open up the Google Form in a new tab. Go to Console, paste the code and boom!!! ProTip: Copy the console log to clipboard and then paste the clipboard contents to a newly created .txt file. You will have your required data in a nice format.

/* 
   It only scraps first 100 emails because other emails are not visible. 
   Whenever I will have time, i will try to work around this problem
   Tested on Firefox 80.0.1
   Not sure about other browsers, (theoretically it should work)

// xpath of div containing emails in a google form
allDivs = $x("//*[contains(text(),'Email') and @class='freebirdAnalyticsViewQuestionTitle']/ancestor::div[@class='freebirdAnalyticsViewAnalyticsHover']")
// get innerText which is essentially emails of all correspondents and also contains some other irrelevant text
uglyData = allDivs[0].innerText.split('\n')
// clean data and append all emails to a string variable and print it in console
emails = ''

  if(uglyData[i].indexOf('@') != -1)
  	emails += uglyData[i].toLowerCase() + "\n"
