Some people have asked me for more info about the SDLXLIFF Converter tool and how it’s used. I had received good instructions from Paul Filkin at SDL for an earlier version some time ago, so I’m sharing them here with his permission. You can download them from here.
By the way, remember also to download and install the Open XML SDK 2.0 application mentioned on the SDLXLIFF Converter page (under Technical Requirements). There are two files on the site, and this is the smaller one of the two (3.8 MB). Without it, the tool doesn’t work and you get an error “Could not load file or assembly ‘DocumentFormat.OpenXml, Version=…” etc. etc. when trying to use the converter – or at least that’s what happened to me when I tried it.
