Is there a better or easier way to transfer/extract data from .lua file (iteminfo_eng.lua) to Excel Format? I have read at the google that I need to convert the lua to json so that they be able to parse the data but all I can find is old solution that dated back 2013 and didnt work for me or I did something wrong. I posted and maybe the rathena forums had a way or a solution to do this. Thanks in Advance.
