Change language of an Indesign document ?

[AndreBellaiche]

How can I change the language from English-UK to French for one Indesign document ? I do not want to change the default language of the application, since I am working simultaneously with the French and English versions of the same document.

Thanks - that works perfectly!

I realize I am several years too late, but just in case someone else looks up this question...

The simplest way to do this is to go into the Paragraph Styles and then edit each style. Once editing, go to the "Advanced Character Formats" and change the language there.

I'm many years late to the table on this one, but after inheriting an English language INDD with the doc language mysteriously set to Polish, I was able to change the doc language this way:

1) Open doc

2) Unlock all layers

3) Select all

4) Go to Characters panel and select "English - US" from the drop-down (or whatever your preferred language is...)

5) Save

Closing and reopening should present a doc with the spelling language set you your preference. You may have to do this separately on your master pages and where template content has been overridden on the spread - but this seems to have worked for me.
