HTML Tidy
Today is apparently Web Developer Tools day.
Ever copy and paste from Work or Outlook, put it online, and have someone call you screaming about “weird characters”?
This is because Microsoft like to “help” you output nice text. Down side is, it comes along with a copy and paste.
Clean that bad markup with HTML Tidy! Paste in a URL, copy and paste text, or upload a file, and outputs neatly structured HTML goodness.
