This is a reupload of a tool from the XeNTaX Forums used to decrypt and convert Dragon Ball Xenoverse 2 .agd files to .xml and back again. Source code has been included as it was uploaded. This is not my original work, however, I am unable to attribute the original author as the original post/tool was deleted from the Forum around 2017/2018.
XeNTaX has also since been shutdown.
Use CriPakTools to extract/unpack files in .cpk format. AgdDecryptor can now be used to convert any .agd files to .xml and back again, such as avatar_growth_data.agd.
