Converts an object to a JSON-formatted string.


              [-InputObject] <Object>
              [-Depth <Int32>]


The ConvertTo-Json cmdlet converts any .NET object to a string in JavaScript Object Notation (JSON) format. The properties are converted to field names, the field values are converted to property values, and the methods are removed.

You can then use the ConvertFrom-Json cmdlet to convert a JSON-formatted string to a JSON object, which is easily managed in PowerShell.

Many web sites use JSON instead of XML to serialize data for communication between servers and web-based apps.

This cmdlet was introduced in Windows PowerShell 3.0.


Example 1

(Get-UICulture).Calendar | ConvertTo-Json

    "MinSupportedDateTime":  "\/Date(-62135596800000)\/",
    "MaxSupportedDateTime":  "\/Date(253402300799999)\/",
    "AlgorithmType":  1,
    "CalendarType":  1,
    "Eras":  [
    "TwoDigitYearMax":  2029,
    "IsReadOnly":  false

This command uses the ConvertTo-Json cmdlet to convert a GregorianCalendar object to a JSON-formatted string.

Example 2

@{Account="User01";Domain="Domain01";Admin="True"} | ConvertTo-Json -Compress


This command shows the effect of using the Compress parameter of ConvertTo-Json. The compression affects only the appearance of the string, not its validity.

Example 3

Get-Date | Select-Object -Property * | ConvertTo-Json

    "DisplayHint":  2,
    "DateTime":  "Friday, January 13, 2012 8:06:16 PM",
    "Date":  "\/Date(1326441600000)\/",
    "Day":  13,
    "DayOfWeek":  5,
    "DayOfYear":  13,
    "Hour":  20,
    "Kind":  2,
    "Millisecond":  221,
    "Minute":  6,
    "Month":  1,
    "Second":  16,
    "Ticks":  634620819762218083,
    "TimeOfDay":  {
                      "Ticks":  723762218083,
                      "Days":  0,
                      "Hours":  20,
                      "Milliseconds":  221,
                      "Minutes":  6,
                      "Seconds":  16,
                      "TotalDays":  0.83768775241087956,
                      "TotalHours":  20.104506057861109,
                      "TotalMilliseconds":  72376221.8083,
                      "TotalMinutes":  1206.2703634716668,
                      "TotalSeconds":  72376.22180829999
    "Year":  2012

This example uses the ConvertTo-Json cmdlet to convert a System.DateTime object from the Get-Date cmdlet to a JSON-formatted string. The command uses the Select-Object cmdlet to get all (*) of the properties of the DateTime object. The output shows the JSON string that ConvertTo-Json returned.

Example 4

Get-Date | Select-Object -Property * | ConvertTo-Json | ConvertFrom-Json

Ticks       : 636749817527683372

              TotalMinutes=1375.87947228667; TotalSeconds=82552.7683372}
Year        : 2018

This example shows how to use the ConvertTo-Json and ConvertFrom-Json cmdlets to convert an object to a JSON string and a JSON object.



Omits white space and indented formatting in the output string.

Default value:None
Accept pipeline input:False
Accept wildcard characters:False


Specifies how many levels of contained objects are included in the JSON representation. The value can be any number from 1 to 100. The default value is 2. ConvertTo-Json emits a warning if the number of levels in an input object exceeds this number.

Default value:2
Accept pipeline input:False
Accept wildcard characters:False


Specifies the objects to convert to JSON format. Enter a variable that contains the objects, or type a command or expression that gets the objects. You can also pipe an object to ConvertTo-Json.

The InputObject parameter is required, but its value can be null ($null) or an empty string. When the input object is $null, ConvertTo-Json does not generate any output. When the input object is an empty string, ConvertTo-Json returns an empty string.

Default value:None
Accept pipeline input:True
Accept wildcard characters:False



You can pipe any object to this cmdlet.



This cmdlet returns a string representing the input object converted to a JSON string.


The ConvertTo-Json cmdlet is implemented using the JavaScriptSerializer class.
