PowerShell 7.3 - how to to Filter CSV Import Based on Dynamic Column Names
I'm wondering if anyone has experience with Can someone help me understand After trying multiple solutions online, I still can't figure this out... I'm currently working with PowerShell 7.3 and trying to import a CSV file where the column names could change dynamically. The goal is to filter the imported data based on a specific column name that I retrieve from another data source at runtime. However, I'm running into issues where the filtering doesn't seem to apply correctly when I use a variable for the column name. I've tried using the `Import-Csv` cmdlet followed by `Where-Object`, but I'm getting an behavior that states `want to convert 'System.String' to the type 'System.Management.Automation.PSObject'`. Here's a simplified version of what I'm doing: ```powershell # Assume the CSV file has columns: Name, Age, Location $csvFile = 'C:\path\to\myfile.csv' $dynamicColumnName = 'Age' # Import the CSV file $data = Import-Csv -Path $csvFile # Attempt to filter based on dynamic column name $filteredData = $data | Where-Object { $_.$dynamicColumnName -gt 30 } ``` The `$dynamicColumnName` variable holds the string 'Age', and I expect `$filteredData` to contain only the entries where 'Age' is greater than 30. However, the behavior about type conversion keeps popping up. I also tried using `Select-Object` to explicitly define the property, but that didn't work either. Is there a better way to achieve this filtering? Any guidance would be appreciated, especially if there are best practices for handling dynamic column names in PowerShell. This is part of a larger API I'm building. The project is a REST API built with Powershell. I'm working with Powershell in a Docker container on Windows 11. Am I approaching this the right way?
