If you develop solutions that need to be executed in several different languages you might need some external party to translate your label files, unless of course you are a linguistic genius.
I have written a small solution with a job that exports labels to a spreadsheet that you can send to an external party. When you get the spreadsheet back, you run a second job which based on the spreadsheet creates an XPO file. Now you can use the standard XPO import tool to analyze the changes and import the labels you want.
The jobs work on AX 2009. I have not tested them with other versions of AX.
You can find both jobs here:
