Export PowerShell output to CSV

Jump to


    PowerShell, a versatile scripting language designed for system administration, produces output that can be incredibly valuable for analysis, sharing, and long-term data storage. Exporting this output to a Comma-Separated Values (CSV) file not only allows for easy creation of spreadsheets but also facilitates the sharing of data with various programs that accept CSV files. This process is crucial when you need to analyze large amounts of data, import it into databases, or share insightful information with colleagues. On this page, we'll delve into what PowerShell output is, the step-by-step method for exporting it to a CSV file, explore various use cases for this exported data, and introduce an alternative method for PowerShell output export using Sourcetable. Additionally, we'll address common questions and provide expert tips to ensure your CSV exports are seamless and effective.

    PowerShell Output

    PowerShell output refers to the data that is produced as a result of executing cmdlets within the PowerShell environment. The primary pipeline or output stream is the mechanism through which this data travels. Cmdlets like Write-Output are used to write objects to this pipeline, displaying them on the console by default at the end of a pipeline. Write-Output is commonly utilized in scripts for presenting strings and other objects. It also enumerates objects within a collection unless the NoEnumerate parameter is invoked to prevent this behavior.

    In the context of querying installed software on a system using PowerShell, the output generated by executing a simple and straightforward command like Get-WmiObject -Class Win32_Product is rich in detail. This output includes metadata about the software such as Caption, InstallDate, InstallSource, PackageName, Vendor, and Version. However, it is important to note that the Win32_Product class is not optimized for querying and its use could potentially initiate a consistency check of packages or even a repair installation.

    As a type of service, PowerShell output can also pertain to the retrieval of information about system services using the Get-Service cmdlet. This cmdlet gathers objects that represent the services on a computer, capturing both running and stopped services. By default, it retrieves services from the local computer, but it can be targeted to fetch details about specific services as well. It is important to mention that the Get-Service cmdlet requires the appropriate permissions to access and display service information and adds additional properties to ServiceController objects such as UserName and StartupType in PowerShell 6.0.

    Exporting PowerShell Output to a CSV File

    Basic CSV Export

    The Export-Csv cmdlet is utilized to create a CSV file from PowerShell objects that are supplied to it. By default, each object is converted into a row with its property values listed and separated by commas. To specify the destination of the CSV file, the -Path parameter is used. The cmdlet's default behavior is to organize the file based on the properties of the first object submitted, and any additional or missing properties in subsequent objects will be handled by adding null values or excluding them, respectively.

    Selecting Specific Properties

    To export only certain properties of an object, the Select-Object cmdlet should be integrated before piping objects to Export-Csv. This allows for more control over the data that is included in the CSV file, ensuring that only the required information is exported.

    Controlling Type Information

    Beginning with PowerShell 6.0, the Export-Csv cmdlet does not include the #TYPE information header by default, as the NoTypeInformation parameter is implied. However, to include this header in the output, the IncludeTypeInformation parameter can be used, which emulates the behavior of Export-Csv in earlier versions of PowerShell.

    Handling Quotes and Culture-Specific Delimiters

    The -UseQuotes parameter determines when quotes are used in the CSV file, while the -QuoteFields parameter specifically quotes the specified columns. Additionally, the -UseCulture parameter allows the use of the current culture's list separator instead of the default comma delimiter, accommodating different regional settings.

    Appending and Overwriting Control

    When adding content to an existing CSV file, the -Append parameter should be used to ensure that the new data is added to the end of the file. The Force parameter is available to overwrite read-only files or to proceed with writing even if some errors occur. The NoClobber parameter, on the other hand, prevents the cmdlet from overwriting existing files.

    Advanced CSV Formatting Options

    Export-Csv cmdlet provides several parameters for advanced control over the CSV output. The Encoding parameter specifies the encoding of the CSV file. The Delimiter parameter allows for a custom delimiter to be set, while the NoHeader parameter can be used to remove the header row containing the column names. The NoTypeInformation switch is available to remove the #TYPE header from the output, and conversely, the IncludeTypeInformation parameter adds the #TYPE information to the CSV file.

    Frequently Asked Questions

    How do I export PowerShell command output to a CSV file?

    Use the Export-Csv cmdlet to convert the PowerShell objects output from a command into CSV strings and save them to a CSV file. Specify the file path using the Path parameter.

    How can I export only specific properties of an object to a CSV file?

    Use the Select-Object cmdlet to select the properties you want to export and pipe the output to Export-Csv. This will include only the specified properties in your CSV file.

    What should I do if I don't want the #TYPE information in my CSV file?

    Use the NoTypeInformation parameter with the Export-Csv cmdlet to exclude the #TYPE information from the CSV output. This is the default behavior in PowerShell 6.0 and later.

    How can I add additional data to an existing CSV file?

    Use the -Append parameter with the Export-Csv cmdlet to add the new CSV output to the end of the existing file.

    What is the difference between Export-Csv and ConvertTo-Csv cmdlets?

    Export-Csv converts PowerShell objects into a CSV string and saves it to a file, while ConvertTo-Csv only returns the CSV string without creating a file.


    In summary, exporting PowerShell output to CSV using the Export-Csv cmdlet is a powerful and versatile operation, ideal for creating spreadsheets and sharing data with CSV-compatible applications. The cmdlet's parameters, such as -NoTypeInformation, -Append, -Delimiter, and -UseCulture, offer fine-grained control over the export process, ensuring the output meets specific requirements. Best practices suggest using Select-Object to tailor the export and taking advantage of PowerShell's version-specific enhancements for optimal results. For those looking for a more streamlined approach to data management, consider bypassing the CSV export process altogether by using Sourcetable.
