Converted code not allowed to run via an online JavaScript unpacker?

I converted existing Github code from python to JavaScript using an online converter to use the script later as a user-script in TamperMonkey in Google Chrome, as I wanted to analyse the converted code for errors via an online JS unpacker it was not allowed to run by Google’s XSS protection that blocked it. Can anyone tell me what is the cause of the blocking opr just a general protection measure from Google’s Safebrowsing?
