This is a revision of @HeartlessSeph script that reassembles FE10Data.cms. It is used the same way the script above is listed, except you do not have to worry about the sheet titled Strings. If you add a new string in a cell, it will be handled automatically. Using Seph’s example, if you added “IID_GURGURANT” you no longer have to add it to the strings list. Do not delete the strings list however, it will cause issues.
Script can be found here!
