What is it?
This site cleans up the HTML for any pasted document. It applies a number of filters to fix various things that Microsoft Office puts in its HTML, and gives you a nicely formatted result that you can paste directly into a web page or content editing system.
Who is behind it?
My name is Oliver Cope and I wrote the software that runs the site. I offer consulting services: http://ollycope.com/.
Is it free?
Yes, this is a completely free service. I hope it will remain so for as long as its running costs can be maintained by advertising.
Is it private?
I'm not at all interested in the contents of your documents. The system is completely automated and no person will ever see what you upload. Furthermore no permanent record of your document is created anywhere.
How does it work?
It uses the Python programming language to manipulate the HTML produced by Microsoft Word. The lxml library does most of the work.
