How to Read Excel Files In Powershell?

To read Excel files in PowerShell, you can use the Import-Excel module or Excel.Application COM object.

With the Import-Excel module, you can directly import an Excel file into a PowerShell object by using the Import-Excel cmdlet.

Another method is to use the Excel.Application COM object to open an Excel file and read its contents using methods like Open, ActiveSheet, Range, Cells, etc.

What is the limitation of reading Excel files in PowerShell?

One limitation of reading Excel files in PowerShell is that PowerShell does not have native support for reading Excel files. While it is possible to read Excel files using PowerShell by leveraging external libraries or COM objects, this approach can be more complex and less efficient compared to using dedicated tools or libraries designed specifically for working with Excel files. Additionally, the performance and compatibility of reading Excel files in PowerShell can vary depending on the version of PowerShell, the Excel file format, and the methods used to read the file.

Install-Module ImportExcel
