JSON Language File Validation

We'r implementing the language abilities of the new HTML5 v2.2 Essentials viewer. After having the language strings translated into French in the Mapping.fr-CA.json.js file, I've merged the language key and it's respective language string using excel.

But now there's some sort of formatting problem with the .js file since the site reverts back to the English version without any indication that something is wrong with my Mapping.fr-CA.json.js file. Even though I've added the &locale=fr-CA at the end of my url string, add have added the fr-CA language in my internet language options, I still get an English version.

Is there a way to check the contents of the .js file to ensure that the proper formats have been adhered to?
