I have an excel file which I converted to JSON file.
Now I want read the Json file path from apex and parse the date into apex.
I did this requirement through lightning and apex, I am loading the excel file thenbased on criteria I am creating records, but I want to do this requirement as script by converting Excel file to JSON then reading JSON file in APEX.

Can anyone give best approach to complete this. Thanks in Avance
