How to Reduce Array to dynamic object in Powershell - powershell

I have a JSON array like this:
$json = [
{ "name": "Name", "value": "Mike" },
{ "name": "Age", "value": 25 },
{ "name": "IsMarried", "value": true }
]
Expected output is this:
{
"Name": "Mike",
"Age": 25,
"IsMarried": true
}
In javascript I would do it this way:
const result = json.reduce((acc, { name, value }) => { acc[name] = value; return acc; }, {})
Question:
Is there an existing function like reduce? How can I achieve same effect?

To 'merge' array items like that, I would use an ordered Hashtable like below:
$json = #'
[
{ "name": "Name", "value": "Mike" },
{ "name": "Age", "value": 25 },
{ "name": "IsMarried", "value": true }
]
'#
# create an ordered Hashtable to store the values
$combine = [ordered]#{}
($json | ConvertFrom-Json) | ForEach-Object {
$combine[$_.Name] = $_.Value
}
# now you can leave it as Hashtable and convert it to JSON
$combine | ConvertTo-Json
# or you can convert (cast) to PsCustomObject first:
# [PsCustomObject]$combine | ConvertTo-Json
Result:
{
"Name": "Mike",
"Age": 25,
"IsMarried": true
}

PowerShell FilterScript error with some JSON Files

Thanks to iRon earlier this week with his help via this question, he helped massively on a piece of work I have on the go at the moment.
In summary, we have an Azure CICD pipeline to deploy out Policies. we have a folder with over 200 JSON policy files and the CICD process brings them all together in 1 JSON file and deploy them out. The initial problem we found was the parameters required a leading extra "[" otherwise the process would fail. And this was highlighted in this article (if you search for [[).
Anyway, to the problem. iRons support helped greatly, but out of the 200 files we get a handful where we receive the following message:
Cannot bind argument to parameter 'FilterScript' because it is null.
The code:
Function supplied by iRon:
function Get-Node {
[CmdletBinding()][OutputType([Object[]])] param(
[ScriptBlock]$Where,
[Parameter(ValueFromPipeLine = $True, Mandatory = $True)]$InputObject,
[Int]$Depth = 10
)
process {
if ($_ -isnot [String] -and $Depth -gt 0) {
if ($_ -is [Collections.IDictionary]) {
if (& $Where) {$_}
$_.get_Values() | Get-Node -Where $Where -Depth ($Depth -1)
}
elseif ($_ -is [Collections.IEnumerable]) {
for ($i = 0; $i -lt $_.get_Count(); $i++) { $_[$i] | Get-Node -Where $Where -Depth ($Depth -1) }
}
elseif ($Nodes = $_.PSObject.Properties.Where{$_.MemberType -eq 'NoteProperty'}) {
$Nodes.ForEach{
if (& $Where) { $_ }
$_.Value | Get-Node -Where $Where -Depth ($Depth -1)
}
}
}
}
}
Where I call the above function (this code is in a loop per file):
$policyRule = #("notIn", "in", "value", "equals", "field", "effect", "like", "greaterOrEquals", "name", "resourceGroupName", "resourceGroup", "location", "storageName", "uniqueStorage", "storageContainerPath", "storageAccountAccessKey", "dependsOn", "targetResourceId", "storageId", "enabled")
if ($content.properties -ne $null){
# Loop all the Policy Rule names for fix the values within them
foreach ($rule in $policyRule){
$Node = $content.properties.policyRule | Get-Node -Where {$_.name -eq $rule -and $_.value -Match "^\[\w+" -and $_.value -ne ""}
$Node | ForEach-Object {$_.Value = '[' + $_.Value}
}
}
A JSON file that works:

As mentioned in my original post, my PowerShell is basic at best and any support would be grateful.
The JSON file whose processing fails contains null values, which turn into $null values in PowerShell when converting the JSON file to an object graph via ConvertFrom-Json.
The Get-Node function as shown in your question doesn't support binding $null to its pipeline-binding -InputObject parameter, which results in an error whenever $_.Value happens to be $null in the following statement:
$_.Value | Get-Node -Where $Where -Depth ($Depth - 1)
The solution is simple: Allow the -InputObject parameter to accept $null, by adding the [AllowNull()] attribute to the original function:
function Get-Node {
[CmdletBinding()][OutputType([Object[]])] param(
[ScriptBlock]$Where,
[AllowNull()] # <- now $null may be passed too
[Parameter(ValueFromPipeLine = $True, Mandatory = $True)]$InputObject,
[Int]$Depth = 10
)
process {
if ($_ -isnot [String] -and $Depth -gt 0) {
if ($_ -is [Collections.IDictionary]) {
if (& $Where) { $_ }
$_.get_Values() | Get-Node -Where $Where -Depth ($Depth - 1)
}
elseif ($_ -is [Collections.IEnumerable]) {
for ($i = 0; $i -lt $_.get_Count(); $i++) { $_[$i] | Get-Node -Where $Where -Depth ($Depth - 1) }
}
elseif ($Nodes = $_.PSObject.Properties.Where{ $_.MemberType -eq 'NoteProperty' }) {
$Nodes.ForEach{
if (& $Where) { $_ }
$_.Value | Get-Node -Where $Where -Depth ($Depth - 1)
}
}
}
}
}

PowerShell Replace value in JSON

In our Azure CICD Pipeline, we have an element where we are trying to deploy Policies. We have JSON file per policy in the repo and we bring all these json files together into one file as part of CI which later is deployed via the CD. The PowerShell wasn't written by me, but a Microsoft consultant who was on site a few years back.
The problem is that when all the JSON comes together, we get an illegal syntax e.g.
Altering the code to this works and deploys, but means we have to go through all our files manually replace [ with [[:
In summary the PowerShell bring all of this together, does some manipulation and outputs to a file in the artifacts folder.
This is just a small snippet of the json, but highlights the area and there are many areas like this in the total json that need replacing:
{
"functions": [
],
"variables": {
"location": "UK South"
},
"resources": [{
"properties": {
"displayName": "Allowed Locations for Resources",
"policyType": "Custom",
"mode": "Indexed",
"description": "description.",
"metadata": {
"version": "1.0.0",
"category": "General"
},
"parameters": {
"listOfAllowedLocations": {
"type": "Array",
"metadata": {
"description": "The list of locations that can be specified when deploying resources.",
"strongType": "location",
"displayName": "Allowed locations"
},
"allowedValues": [
"uksouth",
"ukwest"
],
"defaultValue": [
"uksouth",
"ukwest"
]
}
},
"policyRule": {
"if": {
"allOf": [{
"field": "location",
"notIn": "[parameters('listOfAllowedLocations')]"
},
{
"field": "location",
"notEquals": "global"
},
{
"field": "type",
"notEquals": "Microsoft.Resources/subscriptions/resourceGroups"
},
{
"field": "type",
"notEquals": "Microsoft.Resources/b2cDirectories"
}
]
},
"then": {
"effect": "audit"
}
}
},
"name": "Policy1",
"apiVersion": "2019-01-01",
"type": "Microsoft.Authorization/policyDefinitions",
"location": "[variables('location')]"
}]
}
My PowerShell is intro level at best, so I am struggling to get a replace working.
I can obtain the offending area and replace it in a Write-Host, but I don't know how to write the back to the originating object with without making a right mess of things:
if ($content.properties.policyRule.if.allOf -ne $null){
foreach ($param in $content.properties.policyRule.if.allOf){
Write-Host "were here..................."
#$param = ($param | ConvertTo-Json -Depth 100 | % { [System.Text.RegularExpressions.Regex]::Unescape($_) })
if ($param.notIn -ne $null){
$param.notIn.replace('[', '[[')
Write-Host $param.notIn
}
}
Any suggestions would be grateful.
The point is that the allOf node contains an array. Due to the member-access enumeration feature you will be able to conveniently read the notIn property but to write to it, you will need to be specific on the index ([0]) in the allOf node:
$Data = ConvertFrom-Json $Json # $Json contains your $Json snippet
$Data.resources.properties.policyRule.if.allOf[0].notIn = "[[parameters('listOfAllowedLocations')]"
$Data |ConvertTo-Json -Depth 9
In case you want to recursively find your items based on e.g. a specific name and value format from a specific property level, you might use this common reusable function to recursively find (and replace) a node in a complex PowerShell object:
function Get-Node {
[CmdletBinding()][OutputType([Object[]])] param(
[ScriptBlock]$Where,
[AllowNull()][Parameter(ValueFromPipeLine = $True, Mandatory = $True)]$InputObject,
[Int]$Depth = 10
)
process {
if ($_ -isnot [String] -and $Depth -gt 0) {
if ($_ -is [Collections.IDictionary]) {
if (& $Where) { $_ }
$_.get_Values() | Get-Node -Where $Where -Depth ($Depth - 1)
}
elseif ($_ -is [Collections.IEnumerable]) {
for ($i = 0; $i -lt $_.get_Count(); $i++) { $_[$i] | Get-Node -Where $Where -Depth ($Depth - 1) }
}
elseif ($Nodes = $_.PSObject.Properties.Where{ $_.MemberType -eq 'NoteProperty' }) {
$Nodes.ForEach{
if (& $Where) { $_ }
$_.Value | Get-Node -Where $Where -Depth ($Depth - 1)
}
}
}
}
}
Usage
Finding node(s) with a specific name and value (-format):
$Node = $Data.resources.properties.policyRule.if |Get-Node -Where {
$_.name -eq 'notIn' -and $_.value -Match "^\[\w+\('\w+'\)\]$"
}
$Node
Value : [parameters('listOfAllowedLocations')]
MemberType : NoteProperty
IsSettable : True
IsGettable : True
TypeNameOfValue : System.String
Name : notIn
IsInstance : True
Replacing the value of the found node(s):
$Node |ForEach-Object {
$_.Value = '[' + $_.Value
}
$Data |ConvertTo-Json -Depth 9

Convert JSON-String to proper Object in Powershell

I spend 3 hours debugging, but I don't get the rootcause.
I have text (in JSON Format) in a variable. I convert it with "Convert-From-JSON" to an actual object. I was hoping that I can then work with the properties of the object. But it does not work :( It seems that the conversion only gives me two tables (status and data). What am I doing wrong?
My code:
$results = {
"status": "FINISHED",
"data": {
"results": [
{
"id": "11565C230500",
"custom": {
"image": "XXXX",
"name": "XXXX",
"articleNumber": "4032423423505"
}
},
{
"id": "22739L5F16243",
"custom": {
"image": "XXXX",
"name": "XXXX",
"articleNumber": "4032423423505"
}
},
{
"id": "3304332724004",
"custom": {
"image": "XXXX",
"name": "XXXX",
"articleNumber": "4032423423505"
}
}
]
}
}
Now putting it as Object:
$resultObject = ConvertFrom-JSON -InputObject $result
Now trying to retrieve:
$resultObject.id | where {$_.id -eq '11565C230500'}
As it is now, you define $results as script block where it should be a string:
$results = #'
{
"status": "FINISHED",
"data": {
"results": [{
"id": "11565C230500",
"custom": {
"image": "XXXX",
"name": "XXXX",
"articleNumber": "4032423423505"
}
},
{
"id": "22739L5F16243",
"custom": {
"image": "XXXX",
"name": "XXXX",
"articleNumber": "4032423423505"
}
},
{
"id": "3304332724004",
"custom": {
"image": "XXXX",
"name": "XXXX",
"articleNumber": "4032423423505"
}
}
]
}
}
'#
Now you can convert it from the JSON string
$resultObject = $results | ConvertFrom-Json
Then, to parse out the nested property, you need to follow the data structure:
$resultObject.data.results | Where-Object {$_.id -eq '11565C230500'}
will give you this:
id custom
-- ------
11565C230500 #{image=XXXX; name=XXXX; articleNumber=4032423423505}
If you want to get the articleNumber from the custom object that contains, dig deeper still:
($resultObject.data.results | Where-Object {$_.id -eq '11565C230500'}).custom.articleNumber
which will return 4032423423505
Assuming the json is single quoted in that example, otherwise it's a scriptblock, and "$results" is used in place of "$result", the id property is underneath data.results. You couldn't examine the id property with where-object if you already expanded it. That's an alternate form of where-object. I'm expanding the "custom" property with the foreach-object alias "%". Note one id number is shorter. Beware convertto-json's default depth of 2.
$results = '{"status":"FINISHED","data":{"results":[
{"id":"11565C230500", "custom":{"image":"XXXX","name":"XXXX","articleNumber":"4032423423505"}},
{"id":"22739L5F16243","custom":{"image":"XXXX","name":"XXXX","articleNumber":"4032423423505"}},
{"id":"3304332724004","custom":{"image":"XXXX","name":"XXXX","articleNumber":"4032423423505"}}
]}}'
$resultObject = ConvertFrom-JSON -InputObject $results
$resultObject.data.results | where id -eq 11565C230500
id custom
-- ------
11565C230500 #{image=XXXX; name=XXXX; articleNumber=4032423423505}
$resultobject.data.results | where id -eq 11565C230500 | % custom
image name articleNumber
----- ---- -------------
XXXX XXXX 4032423423505

Powershell Iterate through multidimensional array of hashtables to find a match and combine values from both arrays

I need to combine values from 2 JSONs:
If there is a match in alerts IDs, I need to create structure, that will take data from both jsons
Result for a match should look like:
$array = #()
$hashtable = #{}
$hashtable.AlertID (does not matter what JSON is it from)
$hashtable.Tags (from JSON 1)
$hashtable.IncidentName (from JSON2)
$hashtable.IncidentID (from JSON2)
$array += $hashtable
I would prefer if this would be done with c style powershell loop.
c style for loop = for ($x = 0; $x -array.count; $x++)

Till now, I was looking into using nested foreach loop to address it but it does not behave like I want. I am looking for for loop as I could use the indexes.
Instead of creating an array of Hashtables, I think it's better to create an array of PsCustomObjects, because outputting the result to console/file/json would be a lot easier then.

$json2 = Get-Content -Path 'X:\json2.json' -Raw | ConvertFrom-Json
$result = foreach ($incident in $json1) {
foreach ($alertId in $incident.AlertId) {
$json2.value | Where-Object { $_.alerts.alertId -eq $alertId } | ForEach-Object {
# output an object with the wanted properties
[PsCustomObject]#{
AlertID = $alertId # from json1
Tags = $incident.Tags # from json1
IncidentName = $_.incidentName # from json2
IncidentID = $_.incidentId # from json2
}
}
}
}
# output on screen
$result | Format-Table -AutoSize # or use Out-GridView
# output to new JSON
$result | ConvertTo-Json
# output to CSV file
$result | Export-Csv -Path 'X:\incidents.csv' -NoTypeInformation
Using your examples, the output to console window is:
AlertID Tags IncidentName IncidentID
------- ---- ------------ ----------
da637563185629568182_-638872186 SINC0008009 Multi-stage incident involving Initial access & Discovery on one endpoint 3

delete a object from the json file using a powershell

In this Question i want to accomplish is that i am trying to delete a specific object in the json file.
But while doing so i am experiencing some difficulties i tried to refer article Iterate over JSON and remove JSON element in PowerShell
and implement the same but however it is deleting the entire element but i want to delete a specific object in the element not the entire element following are the required things
1. json file
{
"name": "JourneyPack",
"description": "Details of the journey across india",
"author": "Sachin",
"version": "1.0.0",
"main": "main.js",
"build": {
"applicationID": "desktop",
"Necessaryfiles": [
"main.js",
"package.json",
],
"Storage": {
"output": "./reunited"
},
"DeatilsOfJourney": [
{
"from": "../Pune",
"to": "../travel/Pune",
"filter": [
"**/*
]
},
{
"from": "../Delhi",
"to": "../travel/Delhi",
"filter": [
"**/*"
]
},
{
"from": "../Jharkhand",
"to": "../travel/Jharkhand",
"filter": [
"**/*"
]
},
],
"IOS": {
"category": "desktop"
},
"Windows": {
"icon": "images/desktopicons/icons.ico",
"target": [
"divfrieght"
],
"publisherName": [

]
},
"divfrieght": {
"PointClick": true,
"standaloneMachine": true,
"allowrise": true,
"allowinstdir": true,
"menu": "JourneyPack"
}
},
"private": true,
}
following is the tried code again this is that i have referred from Iterate over JSON and remove JSON element in PowerShell
2. tried code
$inputFile = '<THE FULL PATH AND FILENAME TO YOUR JSON FILE>'
$outputFile = '<THE FULL PATH AND FILENAME FOR THE OUTPUT JSON FILE>'
$apijson = Get-Content -Path $inputFile -Raw | ConvertFrom-Json
# for safety, first make a copy of the original .paths object
$newPaths = $apijson.paths
foreach ($element in $newPaths.PSObject.Properties) {
$objName = $element.Name
$objValue = $element.Value
$objProperties = $objValue.PSObject.Properties
foreach ($prop in $objProperties) {
if ($prop.Value.'from' -eq 'Jharkhand') {
$propName = $prop.Name
$objProperties.Remove($propName)
Write-Host "Removed object $objName -- $propName"
}
}
}
# now overwrite the $apijson.paths with this cleaned up version
$apijson.paths = $newPaths
# I assume you want to convert it back to a .JSON file??
$apijson | ConvertTo-Json -Depth 100 | Set-Content -Path $outputFile -Force
i want to delete the object where "from" is equal to "../Jharkhand/"

if anyone could help that would be really helpful
".paths" property does not belong to you json file, so removed this part of your script.
# for safety, first make a copy of the original .paths object
$newPaths = $apijson.paths
Try this code:
$inputFile = 'input.json'
$outputFile = 'output.json'
$apijson = Get-Content -Path $inputFile -Raw | ConvertFrom-Json
foreach ($element in $apijson.PSObject.Properties) {
$objName = $element.Name
$objValue = $element.Value
$objProperties = $objValue.PSObject.Properties
foreach ($prop in $objProperties) {
# Your object lies in this array
if ($prop.Name -eq 'DeatilsOfJourney') {
[System.Collections.ArrayList]$arr = $prop.Value
#Iterate over your array and find that object which you want to remove
for ($i = 0; $i -lt $arr.count; $i++) {
if ($arr[$i].'from' -eq '../Jharkhand')
{
$arr.RemoveAt($i)
$i--
}
}
$prop.Value = $arr
}
}
}
$apijson | ConvertTo-Json -Depth 100 | Set-Content -Path $outputFile -Force
