I want to change the proofing language of all my slides in a Powerpoint. I've tried setting the language via the Language Preferences menu, however this only changes it for new powerpoints.
I know an answer has already been accepted, but that only changes the proofing language of a single text box, and requires you to change all of them manually.
To change the language of the entire power point easily, open the View tab and select the Outline view.
Likewise while you have everything selected you can change other things like fonts, colours etc. Although of course in many case this is better done by changing the slide master, a presentation that has had many editors may have lots of 'hard' formatting set which deviates from the underlying master and needs resetting to be consistent. You can also reset individual slides to the master style, but this may result in placeholders moving as well, which may be undesirable in some situations.
As for me - PowerPoint restart was needed. Probably because I also did changed Editing Language:
Using Powerpoint 2010 I opened the Outline menu -
Selected all text (Ctrl+A), opened the language menu and set my proofing language
And it worked!
The language menu is located on the Review ribbon tab (after the Slide Show tab and not visible on the screenshot).
The existing answers work for text that is present in the outline. Unfortunately in my case this didn't cover a significant part of the text, including figures, tables, etc.
This macro solved the problem for me :
The "msoLanguageIDEnglishUS" which is used in the above macro can be replaced by any desired language. The full list of languages can be found in this article
(Credit goes to Ganesh Kumar who posted the original macro here. I added support for first level of shape grouping. To further improve it the macro can be made recursive to look for groups which contain other groups, etc.)
I improved upon Inigo's answer to provide a recursive version that changes all items to the desired language.
This version will recursively investigate each shape that is a group type. Some experimentation suggests that
The version of Duncan works well for everything but tables. I found another code which seems to also work with tables: http://stackoverflow.com/questions/4735765/powerpoint-2007-set-language-on-tables-charts-etc-that-contains-text
