There are two ways to do this, if your CSV file has headers, then you can select only the column that you need: Import-Csv -Path c:\temp\test.csv | select DisplayName,Title | FtĪnother option is to use the -header parameter, but this only works well when you only need the first column (or the first couple of columns). But when working with large files it can be useful to only select the data that you really need. When you import a CSV file into PowerShell it will import all the columns by default. Taken the CSV file example that I have added at the beginning of the article, we can get the mailbox of each user using the UserPrincipalName like this: Import-CSV -Path C:\temp\test.csv | ForEach How to Import only specific fields with Import-CSV Inside the ForEach block, we can reference each column of the CSV file as a property of the user object in this case. To do this we can combine the Import CSV cmdlet with ForEach. For example to get the mailbox permissions or OneDrive folder size. Most of the time when you import a CSV file in PowerShell you want to walk through each line of the CSV file. If you want to know what the default delimiter is on your computer, then you can use the following PowerShell command to get the culture information: (Get-Culture).TextInfo.ListSeparator Powershell Import CSV ForEach Or use the system default delimiter with the -UseCulture parameter: $users = Import-Csv -Path c:\temp\test.csv -UseCulture We can use the -delimiter parameter to specify the correct delimiter: $users = Import-Csv -Path c:\temp\test.csv -Delimiter So when I create in CSV file in Excel that I want to use in PowerShell, I will need to either change the delimiter in the CSV file or specify the correct delimiter in PowerShell. But here in the Netherlands for example, is the default delimiter in Excel for CSV files is. By default, the Import-CSV cmdlet uses the, as the delimited. $users.DisplayName Specifying the DelimiterĪ common issue when it comes to import a CSV file with PowerShell is that the delimiter is not recognized. If you store the results of the import cmdlet into a variable, then you can reference each column as a property using the column name (header): $users = Import-Csv -Path c:\temp\test.csv As you can see, we now have all our users with all columns nicely in PowerShell. In this case, we don’t store the results into a variable, but immediately output it into a table with ft. To import this CSV file into PowerShell we can simply use the following command: Import-CSV -Path c:\temp\test.csv | ft This CSV file already had headers for each column, so we don’t need to worry about that for now. ,"Isaiah Langer","Sales Rep","Member","True" ,"Alex Wilber","Marketing Assistant","Member","True" ,"Joni Sherman","recruiter","Member","False" ,"Johanna Lorenz","Senior Engineer","Member","True" ,"Miriam Graham","Director","Member","True" ,"Grady Archie","sr engineer","Member","True" ,"Megan Bowen","recruiter","Member","True" I have created the following CSV file that I will use in the examples below: UserPrincipalName,"DisplayName","Title","UserType","IsLicensed" We are going to start with a simple list of users that we can import in PowerShell.
