web-encode-decode.js     : JavaScript to encode and decode any given string.
web-custom-google-forms  : Make forms on your website and submit on Google forms pragmatically.

web-custom-google-forms

Step 1. Make a form with required fields then open the dev-tools on browser and make a fake submsission.

Step 2. In the tab used for network analysis, look for POST request created by the site to submit.
You'll find the ID of all the questions and the methode used by Google to take in the response.

Step 3. Fill the information accordingly in the link below:
https://docs.google.com/forms/d/[YOURFORMID]/formResponse?entry.[YOURQUESTION1IDHERE]=[YOURQUESTION1ANSWERHERE]&entry.[YOURQUESTION2IDHERE]=[YOURQUESTION2ANSWERHERE]&submit=Submit

Step 4. Complete! You can now take the response from user and submit it to the form using JavaScript.
