You should checkout powershell; it supports converting CSV into in-memory structured data and then you can run regular powershell queries on that data:

    $> csvData = @"
       Name,Department,Salary
       John Doe,IT,60000
       Jane Smith,Finance,75000
       Alice Johnson,HR,65000
       Bob Anderson,IT,71000
       "@;
    
    $> csvData
         | ConvertFrom-Csv
         | Select Name, Salary
         | Sort Salary -Descending
    
       Name          Salary
       ----          ------
       Jane Smith    75000
       Bob Anderson  71000
       Alice Johnson 65000
       John Doe      60000

You can also then convert the results back into CSV by piping into ConvertTo-Csv

    $> csvData
         | ConvertFrom-Csv
         | Select Name, Salary
         | Sort Salary -Descending
         | ConvertTo-Csv
         
       "Name","Salary"
       "Jane Smith","75000"
       "Bob Anderson","71000"
       "Alice Johnson","65000"
       "John Doe","60000"
