I have one json file mytest.json like below I want to update values using PowerShell script
update.json
{
"update": [
{
"Name": "test1",
"Version": "2.1"
},
{
"Name": "test2",
"Version": "2.1"
}
]
}
I want to write a PowerShell script where if Name=="test1" I want to update Version= "3"
How can i do it using parameters?
Here is a way :
$a = Get-Content 'D:\temp\mytest.json' -raw | ConvertFrom-Json
$a.update | % {if($_.name -eq 'test1'){$_.version=3.0}}
$a | ConvertTo-Json -depth 32| set-content 'D:\temp\mytestBis.json'
According to @FLGMwt and @mikemaccana I improve the ConvertTo-Json with -depth 32 because the default depth value is 2 and for object deeper than 2 you will receive class informations in spite of objects.
ConvertTo-Json has a default depth of 2. Deep json will get ToString'd which is probably not what you want. If you have more nested json, use the Depth parameter: ConvertTo-Json -Depth 20
depth issue: learn.microsoft.com/en-us/powershell/module/…
depth, but 1000 is a bit to important. I also add a small explanation.I have also faced the same kind of issue. I was looking to change the records of the below JSON file
{
"SQS_QUEUE_URL": "https://que-url.com/server1",
"SQS_EVENTS_QUEUE_URL": "https://events-server.com/server1/development_events",
"REGION": "region1",
"BUCKET": "test-bucket",
"AE_WORK_PATH": "C:\\workpath\\path1",
"ENV": "env"
}
Finally, I managed to find the easiest way to generate a JSON file from Powershell.
$json = Get-Content "c:\users\bharat.gadade\desktop\test.json" | ConvertFrom-Json
$json.SQS_QUEUE_URL = "https://que-url.com/server2"
$json.SQS_EVENTS_QUEUE_URL = "https://events-server.com/Server2/development_events"
$json.REGION = "region1 "
$json.BUCKET = "test-bucket"
$json.AE_WORK_PATH = "C:\workpath\path1"
$json.ENV = "env"
$json | ConvertTo-Json | Out-File "c:\users\bharat.gadade\desktop\test.json"
