The Export-CSV cmdlet is a PowerShell function that I use quite a lot. Get-Process | export-csv -Path c:\temp\process.csv -UseQuotes AsNeeded Wrapping Up If you are using PowerShell 7 then you can use the -UseQuotes parameter. On some occasions, you might don’t want that. When you export objects in PowerShell 5 or 6 then all values are wrapped in quotation marks. Make sure though that you enclose the new delimiter in quotation marks: Get-AzureADUser | Select-Object -Property userprincipalname, displayname, jobtitle, department, city | Export-CSV c:\temp\azureaduser.csv -NoTypeInformation -Delimiter ' ' UseQuotes So when you need to import the data into another application that required a semicolon ( ) for example, then you can change the delimiter. Not all applications follow this standard. The values in a Comma Separated Values File (CSV) are by default separated with a comma. This way, if the file already exists, you will get an error, preventing you from overwriting the file. If you don’t want this then you can add the -NoClobber parameter. NoClobberīy default, the Export-CSV cmdlet will overwrite any existing file when used. There are a couple of other parameters that are useful when you are using the Export-CSV cmdlet in PowerShell. Other useful Export-CSV parameters in PowerShell It will only write the properties that match though, other properties are discarded. This way the CSV file will be created if it doesn’t exist and objects that have mismatched properties can still be written to the CSV file. $user | Export-CSV c:\temp\usermanager.csv -Append -NoTypeInformation -Force $Manager = Get-AzureADUserManager -ObjectId $_.ObjectId With the -append switch we can add the user to the CSV file. Tip Learn more about creating PowerShell Scripts in this complete guideįor this example, we create a custom PowerShell object that will hold the user information and the manager. There is a more efficient way to do this, but in this case, we are going to loop through all the users and get the manager from Azure AD. Let’s say we want to add the manager of each user to the list. On some occasions, you may want to append information to a CSV file with PowerShell. This will return the selected fields from each user in a nice CSV file that we can actually use: Appending to CSV file with PowerShell Get-AzureADUser | select userprincipalname, displayname, jobtitle, department, city | Export-CSV c:\temp\azureaduser.csv -NoTypeInformation What we need to do is first select the correct information (properties) that we need before we export the user objects to a CSV file. If we look up a single Azure AD user then you can see all the data that is returned from a single user object: Get-AzureADUser -Filter "Displayname eq 'Rudy Mens'" | select * How to Export the correct information with Export-CSV So why is this happening? The Export-CSV cmdlet exports all the individual objects from the Get-AzureADUser cmdlet. Sounds easy, right? Well if you open the CSV file you will notice that we got a bit more than we needed and not the nice list that we had seen in PowerShell before. To do this we can simply pipe the Export-CSV cmdlet behind it: Get-AzureADUser | Export-Csv c:\temp\azureadusers.csv -NoTypeInformation What we are going to do is to export this output to a CSV file. The Get-AzureADUser cmdlet returns all the users in your Microsoft 365 tenant, as you can see in the screenshot below. I am going to use Azure AD throughout the examples here, so if you want to follow along, make sure you connect the Azure AD first. We are going to start with something simple, exporting our Microsoft 365 users to a CSV file. UseQuotes – (PowerShell 7 only) wrap values in quotes or not.NoClobber – Don’t overwrite existing files.Force – Useful in combination with Append.Append – Append to an existing CSV file.Delimiter – Default is comma, but you can change it.NoTypeInformation – Removes the Type information header from the output.Path – (Required) Location of the CSV file.The Export-CSV cmdlet is pretty straightforward and only has a few properties that are useful: In this article, we are going to take a look at how to use the Export-CSV function, how to prevent common mistakes, and what different options there are that you can use. If you only need a CSV string, then you can also use the ConvertTo-CSV function in PowerShell. The Export-CSV function converts PowerShell objects into a CSV string and saves them into a CSV file. To do this we can use the Export-CSV function in PowerShell. But sometimes you need to process this information further in Excel or another system. With PowerShell, you can extract all kinds of information from services like Active Directory or Microsoft 365.
