Thank you for this quick reply, John!

Using Outline View is something I somehow rarely think of in PPT, but since it takes care of all placeholder text throughout the presentation it definitely solves that part of the problem.

The add-in looks interesting, just a few questions:
- Since there is mentioned on the linked page 'found every occurance of the old language' > does this mean you have to select 1 old language to be replaced by 1 new one, or will ALL the text be selected and set to the 1 new language, even if the old language is in fact maybe 2 or more different languages?
- Does this add-in also work in PPT2013?

Thanks again!
Judith.
