converting to json file to bulk upload the extended schema but from sql server not a csv

[ynezar]

i have modified a bit in the original script to be able to read from a sql table directly without the need to export the data in a csv format and it works perfectly all the users are provisioned without problems but when i try to extend the schema for custom attributes like the hire date i need to convert the data in the table to a json file to write it in microsoft graph and it outputs a very large json file which is truncated.....any help?
