How to Use this Script

This script is using Newtonsoft.Json.dll library.

You can download the file here: https://github.com/JamesNK/Newtonsoft.Json/releases

You need to change the DLL path in the script. Please look for this line as reference and replace the path:

    [Reflection.Assembly]::LoadFile

Create a folder and add all JSON files that you would like to process and change the folder path at:

    $folderPath = "C:\AffectedJSONFiles"

The script will process all files on this folder.

You have two scripts available:

    FixJSONFiles-SingleThread
    FixJSONFiles-MultiThread

The SingleThread will process all files in sequence.

The MultiThread will process files simultaneously based in the $Jobs variable. By default it will look for 4 files at the same time.
