How To Export PowerShell Custom Object to CSV
Get deep insights into your CSV data with Sourcetable AI. Create custom charts, formulas, and reports. No Excel skills required.
Introduction
PowerShell is a versatile automation tool widely used for task automation and configuration management. One key feature is its ability to work with custom objects, which are often needed for complex scripts.
Exporting these custom objects to CSV files is a common requirement for further analysis. This webpage provides a step-by-step guide on how to smoothly export your PowerShell custom objects to CSV format.
Additionally, you'll explore how Sourcetable lets you analyze your exported data with AI in a simple to use spreadsheet.
Exporting PowerShell Custom Objects to CSV
- PowerShell offers robust capabilities for manipulating and exporting data, particularly custom objects, to CSV files. This functionality is crucial for data sharing and creating spreadsheets. Exporting custom objects to CSV in PowerShell is streamlined through the <code>Export-Csv</code> cmdlet.
- To export data to a CSV file, PowerShell uses the <code>Export-Csv</code> cmdlet. This cmdlet converts objects into a series of CSV strings and saves them to a specified file path. It requires an input object array, typically custom objects, to generate the CSV file.
- The typical command for exporting a custom object array to a CSV file is:
- <code>$customObjectArray | Export-Csv -Path 'output.csv'</code>
- This command directs PowerShell to convert the <code>$customObjectArray</code> into CSV format and save it as <code>output.csv</code> in the current directory.
- The <code>-Path</code> parameter specifies where to save the CSV file. Without specifying a full path, the file is saved in the current directory. The <code>-NoTypeInformation</code> parameter omits the type information header from the CSV output, streamlining the file for readability.
- Use the <code>Select-Object</code> cmdlet to export only specific properties of a custom object. For example:
- <code>$customObjectArray | Select-Object Property1, Property2 | Export-Csv -Path 'output.csv'</code>
- This command exports only the <code>Property1</code> and <code>Property2</code> properties of each object in the array.
- Additional parameters enhance the csv export process:<ul><li><code>-Delimiter</code>: Changes the delimiter from the default comma to another character, like a semicolon.</li><li><code>-Encoding</code>: Sets the text encoding for the CSV file, such as UTF-8.</li><li><code>-Append</code>: Adds data to the end of an existing CSV file.</li><li><code>-Force</code>: Overwrites a read-only file if necessary.</li></ul>
- <code>-Delimiter</code>: Changes the delimiter from the default comma to another character, like a semicolon.
- <code>-Encoding</code>: Sets the text encoding for the CSV file, such as UTF-8.
- <code>-Append</code>: Adds data to the end of an existing CSV file.
- <code>-Force</code>: Overwrites a read-only file if necessary.
- The <code>Get-Process</code> cmdlet can be used with <code>Export-Csv</code> to export detailed process information:
- <code>Get-Process | Export-Csv -Path 'processes.csv' -NoTypeInformation</code>
- This command exports all active process information to <code>processes.csv</code>, omitting type information for a cleaner CSV file.
- Exporting custom objects to CSV in PowerShell is a powerful and flexible way to handle and share data. By understanding and utilizing the <code>Export-Csv</code> cmdlet and its parameters, users can efficiently create CSV files suited to their specific needs.

How to Export Your Data to CSV Format from PowerShell Custom Object
Using Export-Csv Cmdlet
To export a custom object array to a CSV file in PowerShell, use the Export-Csv cmdlet. This cmdlet converts the custom object array into CSV format and saves it to the specified path. Applications like Excel and Notepad can open the CSV file.
Export-Csv Cmdlet Syntax
The Export-Csv cmdlet creates a CSV file by taking objects passed to it and converting them into a character-separated list of property values. Each object in the array becomes a row in the CSV file. The row contains a list of the object's property values.
Removing Type Information
By default, PowerShell versions from 6.0 onwards do not include the #TYPE information in the CSV output. To exclude this header, use the -NoTypeInformation parameter. Including this parameter helps create cleaner CSV files that are more widely compatible with other software.
Example Usage
Here is an example of how to export processes to a CSV file:
Another example involves exporting selected properties of services:
Additional Parameters
The Export-Csv cmdlet offers several additional settings:
-Delimiter: Specify a custom delimiter such as a semicolon.-IncludeTypeInformation: Include the type information in the CSV file.-Append: Append the CSV output to an existing file.-UseCulture: Use the current culture's list separator.
-Delimiter: Specify a custom delimiter such as a semicolon.-IncludeTypeInformation: Include the type information in the CSV file.-Append: Append the CSV output to an existing file.-UseCulture: Use the current culture's list separator.Creating Spreadsheets and Sharing Data
The Export-Csv cmdlet allows you to create spreadsheets that can share data with other programs. Ensure that objects are not formatted before sending them to Export-Csv to avoid including format properties instead of object properties.
Selecting Specific Properties
To export only specific properties of an object, use the Select-Object cmdlet before Export-Csv. This approach filters the object's properties, ensuring that only the required data is included in the CSV file.
Common Issues
Ensure that objects are not formatted before sending them to Export-Csv to avoid CSV files with unnecessary format properties. Use Select-Object to filter out only the required properties to include in your output file.

Use Cases Unlocked by PowerShell Custom Objects
Creating Structured Data Effortlessly |
PowerShell custom objects enable the creation of structured data easily, making it simpler for administrators and developers to handle output and data manipulation tasks. Using PSCustomObject, one can create well-organized, standardized data structures without relying on more complex methods such as hashtables. |
Simplifying Import and Export Processes |
PSCustomObject streamlines the import and export of data, facilitating easier data handling and interchange. Custom objects make it straightforward to convert data to and from different formats, such as JSON or CSV, enhancing the usability of exported data. |
Enhancing Command and Function Application |
Integrating PSCustomObject into functions or commands can make them far more suitable for advanced use cases. By using custom objects, one can produce outputs that are more aligned with the requirements of complex scripting scenarios, thereby improving the effectiveness of automation scripts. |
