How can I distill Track Changes text into formatted text?

I’ve got a document with some tracked changes, and I need to submit an electronic copy with changes marked in the usual Track Changes way—strikethru for removed text, etc—but if I submit the actual current file, it displays differently on some machines, and for bureaucratic reasons they’re not willing to just fix their settings. So it’s on me to take my metadata-rich change-tracked file and turn it into a file with strikethru and bold and italic. But I can’t figure out how to do that; copy and paste just pastes the newer version of the text, and I can’t find any save/export options that let me do this (though I can change how they’re displayed on my machine).

So… where should I be looking for this?

You said the text displays differently on some machines, but you didn’t say what are the differences.

That’s by design—different people display their changes differently (Word seems to default to different things in different circumstances, e.g. sometimes just showing a vertical bar in the margin). None of which is incorrect behaviour or the least bit LibreOffice’s fault.

That does not answer my question.

Aside from the fact your question is irrelevant to mine, I did answer it (“sometimes just showing a vertical bar in the margin”). More broadly, since people can configure how Track Changes appear (in both LibreOffice and Word), they could potentially appear pretty much any way someone wants but this still doesn’t solve my problem, which is that my local Powers That Be don’t want files in Track Changes format, but with explicit strikethru and bold and so on.
