The title explains what I want to do.
To but to elaborate the document was a short coding standards document. Something with a lot of spaces and a few words per line. It was badly chugging and slow to update whenever I tried to type.
It was bad enough that I just copied out the documented, edited it in something local, and copied it back to the confluence page.
Fortunately none of the other documents for the team have been converted (as they are longer, denser, and include images), but I'd like to know if I can undo this change.
