My script takes a CSV file of strings and then creates an XML file for Android and a .strings file to be used for iOS. It separates each locale meaning that a file will be created for each language.

This has come in handy so far, making localising mobile apps easier. However, I am always seeking feedback so let me know what you think.

Input

The .csv is provided in the format: key, language1, language2

key,en,ru
welcome_message,hello,здравствуйте
thank_you_message,thank you,спасибо
goodbye_message,goodbye,До свидания

Output

XML - Android

en_strings.xml

<?xml version="1.0" ?>
<resources>
    <string name="welcome_message">hello</string>
    <string name="thank_you_message">thank you</string>
    <string name="goodbye_message">goodbye</string>
</resources>

ru_strings.xml

<?xml version="1.0" ?>
<resources>
    <string name="welcome_message">здравствуйте</string>
    <string name="thank_you_message">спасибо</string>
    <string name="goodbye_message">До свидания</string>
</resources>

.Strings - iOS

en.strings

/*  */
"welcome_message" = "hello";

/*  */
"thank_you_message" = "thank you";

/*  */
"goodbye_message" = "goodbye";

ru.strings

/*  */
"welcome_message" = "здравствуйте";

/*  */
"thank_you_message" = "спасибо";

/*  */
"goodbye_message" = "До свидания";

At the moment I've just hardcoded the origin Strings.csv file and the user defines the target directory, this will be useful when integrating it into automatic builds etc.
