I was "blessed" with a couple of those documents not too long ago when I was doing the pandemic sitrep. Those which are formatted in such a psychotic fashion that you can't figure out what's going on when you try to edit, apply styles,etc.

I just pasted them into notepad, cleaned it up and then re-pasted the clean version into the sitrep and re-did the formatting.

I'm still not sure if it was more or less work, but at least it wasn't full of unpleasant surprises at every turn.
