If you upload a .zip file (don't know about the other formats) to Google Docs, it can access its content.
There are probably other services/tools, because technically, there's nothing stopping you from unzipping files in the cloud, or in web based software. It's just the matter of uploading something and then downloading the content after it's been unzipped on the remote server. So it's just more expensive in terms of network traffic.
The availability of the tools that do that, other than Google Docs, is another thing. Honestly wouldn't know, don't recall ever needing it before.
