How can I stop "Word is finishing analyzing your document"?

How to stop word 'finishing analysing your document' - Go to: Word/preferences/edit. Then untick 'keep track of formatting'. It'll stop this from happening.

Note however - if you want to 'select all' (from the 'style' box - when selecting a style-type to change), you need to re-tick the above box.

The problem is inherent to Word, and has nothing to do with any add-ins or any of the settings you mention in your list. The process can be stopped by pressing Command ⌘ + ., but as soon as you take any other action, it will start again. Based on tests I have done, it results from a combination of having tracked changes in the document (even if revision-tracking is turned off) plus automatic page numbering plus a table of contents (or of figures or tables).

If you accept all changes and do no more tracking, Word will stop analyzing the document, regardless of TOCs or automatic page numbering. Or if you leave the tracked changes, Word will stop analyzing the document if you delete both the automatic page numbering (in the footer) from all sections AND the table(s) of contents.

I work on lots of huge Word documents, so I took the trouble to do systematic tests to figure out why Word was constantly stopping to analyze the document. Unfortunately, most of my clients require revision-tracking!

I had this same problem. I tried all the various suggestions--including those that clearly did not apply to me--and nothing worked. I was literally going to return this MacBook Pro...then I notice a note about copying and pasting the whole document into a new black document and it worked! My starting point was a ~500 page Word 2003 document from a PC. I had already "Converted" it in Mac Word and that hadn't helped. I selected all, copy, and pasted the entire thing in a new blank document and it worked. In fact, I doubled the document size just to be sure and no issues. I've been trying to stress-test it by running various commands and trying various options. So far I've been able to make it go into "finishing analyzing" for only a few seconds at most. I'm so relieved.

I think I found a way to run from it - at least has been working. Open Word and create a blank page; don't write anything; then open the file that you wish to edit and it will open without analysing.
