Hi Tom, I really like Pathbuilder for 1e and 2e. Someone would either need to build an API mod/script to handle the conversion or the sheet itself could be modified to include a method for importing the json text and parsing it into the appropriate attributes. If this is a roll20 sheet, it's very unlikely that the sheet could be modified since the code for official sheets are not made available to the public. Either way, it's a very big task.
