ScriptConfig PowerShell Module

PowerShell Module to handle configuration files for PowerShell controller scripts.


With the ScriptConfig module, configuration data can be loaded into a PowerShell controller script from a dedicated config file. Thanks to the module, it is no longer necessary to hard-code or paramter-pass the configuration data. Especially useful for scripts, which run unattended. The module support XML, JSON and INI formatted config files. Works great in cooperation with the ScriptLogger module to improve controller scripts.


The following minimum requirements are necessary to use this module:

  • Windows PowerShell 3.0
  • Windows Server 2008 R2 / Windows 7


With PowerShell 5.0, the new PowerShell Gallery was introduced. Additionally, the new module PowerShellGet was added to the default WMF 5.0 installation. With the cmdlet Install-Module, a published module from the PowerShell Gallery can be downloaded and installed directly within the PowerShell host, optionally with the scope definition:

Install-Module ScriptConfig [-Scope {CurrentUser | AllUsers}]

Alternatively, download the latest release from GitHub and install the module manually on your local system:

  1. Download the latest release from GitHub as a ZIP file: GitHub Releases
  2. Extract the module and install it: Installing a PowerShell Module


  • Get-ScriptConfig
    Loads the configuration from a config file. The path and format can be specified with parameters.


In this example, a JSON configuration file is loaded into the script. You will find an example configuration file in the after next chapter. As soon as you have imported the configuration data, you will be able to use the returned object to access the settings with the . notation. All available formats for the config files are listed in the next chapter.

# Load the configuration from a config file
$config = Get-ScriptConfig -Path 'C:\Scripts\config.json' -Format JSON

# Access the configuration data from the config variable
Write-Host "Config Data:" $config.MyString

Supported Types

The cmdlet supports multiple types. Depending on the used format, the types have to be specified differently inside the config file.

Type Description
String A settings is stored as a string by default.
Integer If the setting value is a valid integer, it will be casted into an integer.
Boolean By specifying the key words True or False, it will be casted to a boolean type.
Array An array of strings can be specified.
Hashtable A dictionary of key-value-pairs is supported too. The key and values will be a string.

XML Format

Inside an XML formatted config file, it's mandatory to specify the type, the key and the value of each setting. Thanks to this, the config file is type-safe.

<?xml version="1.0" encoding="utf-8"?>
        <Setting Type="string" Key="MyString" Value="This is a test XML config file!" />
        <Setting Type="integer" Key="MyIntegerPositive" Value="42" />
        <Setting Type="integer" Key="MyIntegerNegative" Value="-153" />
        <Setting Type="boolean" Key="MyBooleanTrue" Value="true" />
        <Setting Type="boolean" Key="MyBooleanFalse" Value="false" />
        <Setting Type="array" Key="MyArray">
            <Item Value="Lorem" />
            <Item Value="Ipsum" />
        <Setting Type="hashtable" Key="MyHashtable">
            <Item Key="Foo" Value="Bar" />
            <Item Key="Hello" Value="World" />

JSON Format

With the JSON format, it's easy to specify the configuraiton data with less overhead. Because of the special notation, the JSON format is also type-safe.

    "MyString":  "This is a test JSON config file!",
    "MyIntegerPositive":  42,
    "MyIntegerNegative":  -153,
    "MyBooleanTrue":  true,
    "MyBooleanFalse":  false,
    "MyArray":  [
    "MyHashtable":  {
                        "Foo": "Bar",
                        "Hello": "World"

INI Format

The last supported format is the INI file. To support all types, it is necessary to extend the basic INI file convention with [ and ], to specify arrays and hash tables. Sections are not supported and will be ignored.

MyString=This is a test INI config file!

Please feel free to contribute by opening new issues or providing pull requests. For the best development experience, open this project as a folder in Visual Studio Code and ensure that the PowerShell extension is installed.

This module is tested with the PowerShell testing framework Pester. To run all tests, just start the included test script .\Scripts\test.ps1 or invoke Pester directly with the Invoke-Pester cmdlet. The tests will automatically download the latest meta test from the claudiospizzi/PowerShellModuleBase repository.

To debug the module, just copy the existing .\Scripts\debug.default.ps1 file to .\Scripts\debug.ps1, which is ignored by git. Now add the command to the debug file and start it.
