I\'ve created a form with about 800 fields in it. Unknowingly I\'ve given same id for few fields in the form. How to trace them?

There is a Chrome extension named Dup-ID which if you install, you just need to press the button to check duplicated ids. Link of install: https://chrome.google.com/webstore/detail/dup-id-scans-html-for-dup/nggpgolddgjmkjioagggmnmddbgedice
