macro/code to export all the parameters information (names, values, tolerances, comments...)

Hi I'm new to the forum, and i hope someone can help me ! :) I'm currently using Inventor 2012 and i need a macro (code): I want to know if it's possible to export all the information from the parameters list (everything, names, values, tolerances, comments...) to an excel spreadsheet or a txt file (it can be a table, or a CVS file, i just want that information!), from a part file (.ipt) or a drawing file (.dwg). Currently, i can only export the parameters' names and values , but i can't get to the tolerance values and comments . . . Is there anyway to do this ? Many thanks, Regards JVC
