Powershel : Convert JSON String to PS Object and Vice-versa

Many software services moving towards cloud environment and providing APIs to communicate with service. To standardize this communication many software APIs use JSON format to receive and return data. In this post, I am going to share powershell script to convert json to object and convert object to json string.

Convert JSON content to PS Object :

You can easily convert json text into object using the powershell cmdlet ConvertFrom-Json. Consider the below sample JSON that might be a HTTP/HTTPS response content returned from some API.

$usersJson = '{"users":[
    { "username":"kevin", "email":"kevin@test.com" },
    { "username":"morgan", "email":"morgan@test.com" },
    { "username":"smith", "email":"smith@test.com" }
]}'

Run the following command to convert the above json string to ps object.

$usersObject = ConvertFrom-Json –InputObject $usersJson

Now you can easily list the ps object properties

PS C:\> $usersObject.users

username email
-------- -----
kevin    kevin@test.com
morgan   morgan@test.com
smith    smith@test.com

Convert PS Object to JSON String :

You can convert the above ps object into json text using the powershell cmdlet ConvertTo-Json.

$newUsersJson = $usersObject | ConvertTo-Json
