Reading XLSX Files in PowerShell Without Excel

In PowerShell, you can read XLSX files without having Microsoft Excel installed on your system. This can be achieved by utilizing the OpenXmlPowerTools module. Here’s how you can do it:

1. Install the OpenXmlPowerTools Module

Before proceeding, you need to install the OpenXmlPowerTools module. Run the following command in PowerShell with administrative privileges to install the module: 

Install-Module -Name OpenXmlPowerTools

2. Import the OpenXmlPowerTools Module

After the module is installed, import it into your PowerShell session by running the following command: 

Import-Module -Name OpenXmlPowerTools

3. Read the XLSX File

Once the module is imported, you can use the Read-Xlsx cmdlet to read the XLSX file. Here’s an example: 

$xlsxFile = "C:\path\to\your\file.xlsx"
$data = Read-Xlsx -Path $xlsxFile

In this example, replace C:\path\to\your\file.xlsx with the actual path to your XLSX file. The $data variable will contain the data from the spreadsheet.

4. Accessing the Data

The data retrieved from the XLSX file will be in the form of a collection of objects. You can access individual cells or rows using PowerShell’s object property syntax. Here’s an example: 

$data | ForEach-Object {
    Write-Output "Cell A: $($_.A)"
    Write-Output "Cell B: $($_.B)"
  }

This example will iterate over each row in the $data collection and print the values in the “A” and “B” columns.

5. Additional Considerations

Keep in mind that the OpenXmlPowerTools module is designed to handle XLSX files and may not work with older XLS file formats. Additionally, the module may not support all features of Excel, such as formatting, macros, or complex formulas.

It is also worth noting that using the OpenXmlPowerTools module requires basic knowledge of PowerShell scripting. You may need to adapt the code examples provided based on your specific requirements and the structure of your XLSX file.
