Converts Microsoft .NET Framework objects into a series of comma-separated value (CSV) variable-length strings and saves the strings in a CSV file.

Syntax

Export-CSV [[-Delimiter] <char>] [-Path] <string> -InputObject <psobject> [-Encoding <string>] [-Force] [-NoClobber] [-NoTypeInformation] [-Confirm] [-WhatIf] [<CommonParameters>]

Export-CSV [-UseCulture] [-Path] <string> -InputObject <psobject> [-Encoding <string>] [-Force] [-NoClobber] [-NoTypeInformation] [-Confirm] [-WhatIf] [<CommonParameters>]

Description

The Export-CSV cmdlet creates a CSV variable-length file that represents the objects that you submit.

You can then use the Import-CSV cmdlet to re-create objects from the CSV strings in the files. The resulting objects are CSV versions of the original objects that consist of string representations of the property values and no methods.

You can also use the ConvertTo-CSV and ConvertFrom-CSV cmdlets to convert .NET Framework objects to CSV strings (and back). Export-CSV is the same as ConvertTo-CSV, except that it saves the CSV strings in a file.

You can use the parameters of the Export-CSV cmdlet to specify a delimiter other than a comma or to direct Export-CSV to use the default delimiter for the current culture.

When you submit multiple objects to Export-CSV, Export-CSV organizes the file based on the properties of the first object that you submit. If the remaining objects do not have one of the specified properties, the property value of that object is null, as represented by two consecutive commas. If the remaining objects have additional properties, those property values are not included in the file.

For more information, see Export-CSV, and see the Notes section.

<CommonParameters>

This cmdlet supports the common parameters: -Verbose, -Debug, -ErrorAction, -ErrorVariable, -OutBuffer, and -OutVariable. For more information, see about_CommonParameters.

Inputs and Outputs

The input type is the type of the objects that you can pipe to the cmdlet. The return type is the type of the objects that the cmdlet returns.

Inputs

System.Management.Automation.PSObject

You can pipe any .NET Framework object to Export-CSV.

Outputs

System.String

The CSV list is sent to the file designated in the Path parameter.

Notes

The Export-CSV cmdlet converts the objects that you submit into a series of CSV variable-length strings and saves them in the specified text file. You can use Export-CSV to save objects in a CSV file and then use the Import-CSV cmdlet to create objects from the text in the CSV file.

In the CSV file, each object is represented by a comma-separated list of the property values of the object. The property values are converted to strings (by using the ToString() method of the object), so they are generally represented by the name of the property value. Export-CSV does not export the methods of the object.

The format of an exported file is as follows:

-- The first line of the CSV file contains the string '#TYPE ' followed by the fully qualified name of the .NET Framework type of the object, such as #TYPE System.Diagnostics.Process. To suppress this line, use the NoTypeInformation parameter.

-- The next line of the CSV file represents the column headers. It contains a comma-separated list of the names of all the properties of the first object.

-- Additional lines of the file consist of comma-separated lists of the property values of each object.

Example 1

C:\PS>get-process wmiprvse | select-object basePriority,ID,SessionID,WorkingSet | export-csv -path data.csv

This command selects a few properties of the wmiprvse process and exports them to a CSV format file named data.csv.






Example 2

C:\PS>get-process | export-csv processes.csv

C:\PS> get-process | export-csv processes.csv 

# In processes.csv

#TYPE System.Diagnostics.Process
__NounName,Name,Handles,VM,WS,PM,NPM,Path,Company,CPU,FileVersion,...
Process,powershell,626,201666560,76058624,61943808,11960,C:\WINDOWS...
Process,powershell,257,151920640,38322176,37052416,7836,C:\WINDOWS\...


Description
-----------
This command exports objects representing the processes on the computer to the Processes.csv file in the current directory. Because it does not specify a delimiter, a comma (,) is used to separate the fields in the file.






Example 3

C:\PS>get-process | export-csv processes.csv -Delimiter ";"

# In processes.csv

#TYPE System.Diagnostics.Process
__NounName;Name;Handles;VM;WS;PM;NPM;Path;Company;CPU;FileVersion;...
Process;powershell;626;201666560;76058624;61943808;11960;C:\WINDOWS...
Process;powershell;257;151920640;38322176;37052416;7836;C:\WINDOWS\...


Description
-----------
This command exports objects representing the processes on the computer to the Processes.csv file in the current directory. It uses the Delimiter parameter to specify the semicolon (;). As a result, the fields in the file are separated by semicolons.






Example 4

C:\PS>get-process | export-csv processes.csv -UseCulture

This command exports objects representing the processes on the computer to the Processes.csv file in the current directory. It uses the UseCulture parameter to direct Export-CSV to use the delimiter specified by the ListSeparator property of the current culture.






Example 5

C:\PS>get-process | export-csv processes.csv -NoTypeInformation

C:\PS> get-process | export-csv processes.csv -NoTypeInformation

# In processes.csv

__NounName,Name,Handles,VM,WS,PM,NPM,Path,Company,CPU,FileVersion,...
Process,powershell,626,201666560,76058624,61943808,11960,C:\WINDOWS...
Process,powershell,257,151920640,38322176,37052416,7836,C:\WINDOWS\...


Description
-----------
This command exports objects representing the processes on the computer to the Processes.csv file in the current directory. It uses the NoTypeInformation parameter to suppress the type information in the file.
