My old man has a bunch of .dox stuff saved. He has complicated large files saved that are not supported by any of the FOSS conversion tools. I’ve tried Libre office, Abi Word, and every command line tool and converter I can find. These are entire book sized files.
I have a W10 machine with Word. Is extracting the .exe and running it with wine feasible without making an epic mess or massive project of this?
Assuming the latest version of OpenOffice doesn’t work for these files…
My next course of action would be using the Win 10 machine with Word, or a VM with Win10 or 11 and the latest version of Word. Use MASGrave to trick M$ into considering it licensed if you need to.
Use a Powershell script to interact with Word through the COM object interface and automate opening Word, opening the file, saving it as a different filetype, and closing. Here’s a snippet of Powershell from Reddit for going in the opposite direction (odt to docx) for a single file. I wouldn’t try to do this through Linux, just suck it up and use Windows so you don’t have an extra layer of mess to deal with.
Going off M$ documentation of the save types enum, I would replace “wdFormatDocumentDefault” in that snippet with wdFormatOpenDocumentText or wdFormatStrictOpenXMLDocument, then test it with a single file to see which gives the output you need.
Getting all the files of the starting type from a folder can be done using Get-ChildItem. Store those in a variable and use a foreach loop over the initial file list.
