Description
The ConvertTo-Html
cmdlet converts .NET objects into HTML that can be displayed in a Web browser. You can use
this cmdlet to display the output of a command in a Web page.
You can use the parameters of ConvertTo-Html
to select object properties, to specify a table or list format, to specify the HTML page title, to add text before and after the object, and to return only the table or list fragment, instead of a strict DTD page.
When you submit multiple objects to ConvertTo-Html
, PowerShell creates the table [or list] 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 an empty cell. If the remaining objects have additional properties, those property values are not included in the file.
Examples
Example 1: Create a web page to display the date
ConvertTo-Html -InputObject [Get-Date]
This command creates an HTML page that displays the properties of the current date. It uses the InputObject parameter to submit
the results of a Get-Date
command to the ConvertTo-Html
cmdlet.
Example 2: Create a web page to display PowerShell aliases
Get-Alias | ConvertTo-Html | Out-File aliases.htm
Invoke-Item aliases.htm
This command creates an HTML page that lists the PowerShell aliases in the current console.
The command uses the Get-Alias
cmdlet to get the aliases. It uses the pipeline operator [|
] to send the aliases to the ConvertTo-Html
cmdlet, which creates the HTML page. The command also uses the
Out-File
cmdlet to send the HTML code to the aliases.htm
file.
Example 3: Create a web page to display PowerShell events
Get-EventLog -LogName "Windows PowerShell" | ConvertTo-Html | Out-File pslog.htm
This command creates an HTML page called pslog.htm
that displays the events in the Windows PowerShell event log on the local computer.
It uses the Get-EventLog
cmdlet to get the events in the Windows PowerShell log and then uses the pipeline operator [|
] to send the events to
the ConvertTo-Html
cmdlet. The command also uses the Out-File
cmdlet to send the HTML code to the pslog.htm
file.
The command also uses the Out-File
cmdlet to send the HTML code to the pslog.htm
file.
Example 4: Create a web page to display processes
Get-Process |
ConvertTo-Html -Property Name, Path, Company -Title "Process Information" |
Out-File proc.htm
Invoke-Item proc.htm
These commands create and open an HTML page that lists the name, path, and company of the processes on the local computer.
The first command uses the Get-Process
cmdlet to
get objects that represent the processes running on the computer. The command uses the pipeline operator [|
] to send the process objects to the ConvertTo-Html
cmdlet.
The command uses the Property parameter to select three properties of the process objects to be included in the table. The command uses the Title parameter to specify a title for the HTML page. The command also uses the Out-File
cmdlet to send the resulting HTML to a file named Proc.htm
.
The second command uses the Invoke-Item
cmdlet to open the Proc.htm
in the default browser.
Example 5: Create a web page to display service objects
Get-Service | ConvertTo-Html -CssUri "test.css"
HTML TABLE
...
This command creates an HTML page of the service objects that the Get-Service
cmdlet returns. The command uses the CssUri parameter to specify a cascading style sheet for the HTML page.
The CssUri parameter adds an additional
tag to the resulting HTML. The HREF attribute in the tag contains the name of the style sheet.
Example 6: Create a web page to display service objects
Get-Service | ConvertTo-Html -As LIST | Out-File services.htm
This command creates an HTML page of the service objects that the Get-Service
cmdlet returns. The command uses the As parameter to specify a list format. The cmdlet Out-File
sends the resulting HTML to the Services.htm
file.
Example 7: Create a web table for the current date
Get-Date | ConvertTo-Html -Fragment
...
DisplayHintDateTimeDateDayDayOfWeekDayOfYearHour
KindMillisecondMinuteMonthSecondTicksTimeOfDayYear
DateTime Monday, May 05, 2008 10:40:04 AM 5/5/2008 12:00:00 AM 5 Monday
126 10 Local 123 40 5 4 633455808041237213 10:40:04.12
37213 2008
This command uses ConvertTo-Html
to generate an HTML table of the current date. The command uses the Get-Date
cmdlet to get the current date. It uses a pipeline operator [|
] to send the results to the ConvertTo-Html
cmdlet.
The ConvertTo-Html
command includes the Fragment parameter, which limits the output to an HTML table. As a result, the other elements of an HTML
page, such as the and
tags, are omitted.
Example 8: Create a web page to display PowerShell events
Get-EventLog -Log "Windows PowerShell" | ConvertTo-Html -Property id, level, task
This command uses the Get-EventLog
cmdlet to get events from the Windows PowerShell event log.
It uses a pipeline operator [|
] to send the events to the ConvertTo-Html
cmdlet, which converts the events to HTML format.
The ConvertTo-Html
command uses the Property parameter to
select only the ID, Level, and Task properties of the event.
Example 9: Create a web page to display specified services
$htmlParams = @{
Title = "Windows Services: Server01"
Body = Get-Date
PreContent = "Generated by Corporate IT
"
PostContent = "For details, contact Corporate IT."
}
Get-Service A* |
ConvertTo-Html @htmlParams |
Out-File Services.htm
Invoke-Item Services.htm
This command creates and opens a Web page that displays the services on the computer that begin with A
. It uses the Title, Body, PreContent, and PostContent parameters of
ConvertTo-Html
to customize the output.
The first part of the command uses the Get-Service
cmdlet to get the services on the computer that begin with A
. The command uses a pipeline operator [|
] to send the results to the ConvertTo-Html
cmdlet. The command also uses the Out-File
cmdlet to send the output to the Services.htm
file.
A semicolon [;
] ends the first command and starts a second command, which uses the Invoke-Item
cmdlet to open the Services.htm
file in the default browser.
Example 10: Set the Meta properties and Charset of the HTML
Get-Service | ConvertTo-HTML -Meta @{
refresh=10
author="Author's Name"
keywords="PowerShell, HTML, ConvertTo-HTML"
} -Charset "UTF-8"
This command creates the HTML for a webpage with the meta tags for refresh, author, and keywords. The charset for the page is set to UTF-8
Example 11: Set the HTML to XHTML Transitional DTD
Get-Service | ConvertTo-HTML -Transitional
This command sets the DOCTYPE
of the returned HTML to XHTML Transitional DTD
Parameters
Determines whether the object is formatted as a table or a list. Valid values are Table and List. The default value is Table.
The Table value generates an HTML table that resembles the PowerShell table format. The header row displays the property names. Each table row represents an object and displays the object's values for each property.
The List value generates a two-column HTML table for each object that resembles the PowerShell list format. The first column displays the property name. The second column displays the property value.

When you pipe multiple objects to a cmdlet, PowerShell sends the objects to the cmdlet one at a time.

ConvertTo-Html
returns series of strings that comprise valid HTML.Notes
ConvertTo-Html
creates a table that displays the individual objects. For example, if you pipe the processes on a computer to ConvertTo-Html
, the resulting table displays all of
the processes.ConvertTo-Html
receives these objects as a collection or as an array. As a result, it creates a table that displays the array and its properties, not the items in the array. For example, if you use InputObject to submit the processes on a computer to ConvertTo-Html
, the resulting table displays an object array and its properties.DOCTYPE
