This nifty little tool was very simple to build but it is very useful. When I build different projects with localization files (files for multi-language support), I always tend to get lost when the files get very large.This tool allows me to verify that all values that are present across all languages.

As I usually develop websites for french and english users, this tool only supports comparison between two languages. I would love to be able to support multiple files at once in the future.
