There are a few reporting tools we use that can't generate wiki markup at this time, but can generate simply formatted Word documents that cleanly convert to Confluence pages using its importer.
What I'd like to explore is whether there's any kind of way to expose Confluence's Word importer as a REST endpoint that our reporting engines can automatically post to. It wouldn't need to do much more than take a doc/docx input, target space and (optionally) parent page, and disable page splitting.
But I realize even that much might be asking for a lot. Any help, or suggested alternatives, is appreciated!
