Utility file converter for converting to .json files

This description is for the purpose of taking MT5 open bar data files to convert them to upload into a server that only accepts MT4 .JSON files.  The utility should be easy to use with only minor steps.  The files also need to work with a .JSON file merge utility I have.  I have the file merger utility to send to aid with development. 

For reference: I already tried “create custom symbol” in MT5 but received the error “Cannot read properties of undefined (reading 'replace')” when trying to upload the MT5 .json file into the server.
