I am recommending to my client to use the built-in translation tool. I am finding in some simple tests that the import is failing on some slides. The exported Word doc appears to be fine. But when I do some test translating from Google Translate into the Word doc, what happens is that text fields will return empty with no text - neither the original English or the translated text. This seems sporadic in that some fields are successfully translated and some are wiped out.
I'd like to get some stability in this process before working through it (15 languages!!) with the client. Has anyone had similar experiences? Did you ever come up with an explanation of what worked and what broke the tool??
