Here is a simple Perl script I put together to help me manage locales. 
The basic approach is to define string CONSTANTS in the spread sheet and then populate them with locale-specific text.
Then you write your app to reference the CONSTANTS and the run time output will use the strings based on the locale.
It still requires your app to use Locale.lua  
https://github.com/ar2rsawseen/Localize or 
BhLocale.lua 
http://giderosmobile.com/forum/discussion/comment/6142#Comment_6142The Perl script parses the Excel file and generates the local files .lua for each locale defined.
The attached zip file also has a sample Gideros project to let you mess around and test the generateLocalesFiles.pl script.
The zip file also contains 
@ar2rsawseen Locale system to allow demonstration. 
Please refer to 
https://github.com/ar2rsawseen/Localize for the latest version.
Hope someone else finds it useful too.
