I have a set of folders in which there are some json files. I am trying to write a powershell script to convert the below line for all the json in the folder:
"objectStatus": "ACTIVE",
The above line from json files can differ with more than one space between the key and value:
"objectStatus": "ACTIVE",
The script that I wrote is:
$jsonFiles = Get-ChildItem . *.json -rec
foreach ($file in $jsonFiles)
{
(Get-Content $file.PSPath) |
Foreach-Object {$_ -replace '"ACTIVE"','"INACTIVE"'} |
Set-Content $file.PSPath
}
You can see that the above replaces the string '"ACTIVE"' to '"INACTIVE"'. However, I want to replace the '"ACTIVE"' string only when the key is "objectStatus". Also, there can be more than one space between the key and value. How can I handle that while replacing the string?
Thanks in advance!
You can make search by full string like this. '"objectStatus":\s*"ACTIVE"','"objectStatus": "INACTIVE"'
$jsonFiles = Get-ChildItem . *.json -rec
foreach ($file in $jsonFiles)
{
(Get-Content $file.PSPath) |
Foreach-Object {$_ -replace '"objectStatus":\s*"ACTIVE"','"objectStatus": "INACTIVE"'} |
Set-Content $file.PSPath
}
Kind of have a strange problem. I have a large JSON file that needs to be processed. Based on another question I need to stream the file since it will otherwise gets me problems because of memory: JSON Powershell memory issue
What I have is this:
get-content -Path largefile.json | ForEach-Object {
$row = $_ = $_.TrimStart('[').TrimEnd(']')
if ($_) { $_ | Out-String | ConvertFrom-Json }
New-Item -Path $($Row.Id).txt
Set-Content -Path $($Row.Id).txt -Value ($row.Body)
}
I can easily do $row to publish the last processed row in the Largefile.json. I want to create a file with the name of the Id in the row that is currently processed and add the body column to the file. But when I want to show a specific column using $row.Id, unfortunately this shows up empty.
The structure of the Largefile.json is as followed:
[{"Id":"1","ParentId":"parent","Name":"filename","OwnerId":"owner","CreatedDate":"date","Body":"data1"}
{"Id":"2","ParentId":"parent","Name":"filename","OwnerId":"owner","CreatedDate":"date","Body":"data2"}
{"Id":"3","ParentId":"parent","Name":"filename","OwnerId":"owner","CreatedDate":"date","Body":"data3"}
{"Id":"4","ParentId":"parent","Name":"filename","OwnerId":"owner","CreatedDate":"date","Body":"data4"}
{"Id":"5","ParentId":"parent","Name":"filename","OwnerId":"owner","CreatedDate":"date","Body":"data5"}
]
The end result should be that I have 5 files:
1.txt - Value inside the file should be: data1
2.txt - Value inside the file should be: data2
3.txt - Value inside the file should be: data3
4.txt - Value inside the file should be: data4
5.txt - Value inside the file should be: data5
I use Powershell 7.1.3
Is there any way that I can use $row.Id and $row.ParentId just like a regular ForEach would do?
thanks for your help.
It seems to me that this is what you're looking for:
Get-Content largefile.json | ForEach-Object {
$row = $_.TrimStart('[').TrimEnd(']') | ConvertFrom-Json
if ($null -ne $row) {
Set-Content -Path ($row.Id) -Value ($row.Body)
}
}
I am still not sure what you expect as an outcome.
But I think you want to do this:
#'
[{"Id":"1","ParentId":"parent1","Name":"1.txt","OwnerId":"owner","CreatedDate":"date","Body":"Data1"}
{"Id":"2","ParentId":"parent2","Name":"2.txt","OwnerId":"owner","CreatedDate":"date","Body":"Data2"}
{"Id":"3","ParentId":"parent3","Name":"3.txt","OwnerId":"owner","CreatedDate":"date","Body":"Data3"}
{"Id":"4","ParentId":"parent4","Name":"4.txt","OwnerId":"owner","CreatedDate":"date","Body":"Data4"}
{"Id":"5","ParentId":"parent5","Name":"5.txt","OwnerId":"owner","CreatedDate":"date","Body":"Data5"}
]
'# | Set-Content .\largefile.json
Get-Content .\largefile.json | ForEach-Object {
$_ = $_.TrimStart('[').TrimEnd(']')
If ($_) {
$Row = ConvertFrom-Json $_
Set-Content -Path ".\$($Row.Name)" -Value $Row.Body
}
}
The question has many errors. Assuming the json has the missing commas in, I would do it this way, if I understand the question. This should work with the new updates to the question. I also have a more unusual solution involving streaming json with jq here: Iterate though huge JSON in powershell Json streaming support may be added later: ConvertFrom-JSON high memory consumption #7698
[{"Id":"ID","ParentId":"parent","Name":"filename","OwnerId":"owner","CreatedDate":"date","Body":"*******"},
{"Id":"ID","ParentId":"parent","Name":"filename","OwnerId":"owner","CreatedDate":"date","Body":"*******"},
{"Id":"ID","ParentId":"parent","Name":"filename","OwnerId":"owner","CreatedDate":"date","Body":"*******"},
{"Id":"ID","ParentId":"parent","Name":"filename","OwnerId":"owner","CreatedDate":"date","Body":"*******"},
{"Id":"ID","ParentId":"parent","Name":"filename","OwnerId":"owner","CreatedDate":"date","Body":"*******"}
]
get-content -Path largefile.json | ForEach-Object {
$_ = $_.TrimStart('[').TrimEnd(']').TrimEnd(',')
if ($_) {
$row = $_ | ConvertFrom-Json
Set-Content -Path ($Row.Id + '.txt') -Value $row.Body
}
}
get-content ID.txt

As others already explained, your json example is invalid.
However, since this is a huge file to process, you can use switch for this.
switch -Regex -File D:\Test\largefile.json {
'"Id":"(\d+)".*"Body":"(\w+)"' {
Set-Content -Path ('D:\Test\{0}.txt' -f $matches[1]) -Value $matches[2]
}
}
Results using your example would be 5 files called 1.txt .. 5.txt, each having a single line data1 .. data5
So I recently have found the need to do a find and replace of mutliple items within a XML document. Currently I have found the code below which will allow me to do multiple find and replaces but these are hard coded within the powershell.
(get-content c:\temp\report2.xml) | foreach-object {$_ -replace "192.168.1.1", "Server1"} | foreach-object {$_ -replace "192.168.1.20", "RandomServername"} | set-content c:\temp\report3.xml
Ideally instead of hard coding the value I would like to find and replace from a list, ideally in a CSV or and XLSX. Maybe two txt file would be easier.
If it was from a CSV it could grab the value to find from A1 and the value to replace it with from B1 and keep looping down until the values are empty.
I understand I would have to use the get-content and the for each command I was just wondering if this was possible and how to go about it/ if anybody could help me.
Thanks in advance.
SG
#next line is to clear output file
$null > c:\temp\report3.xml
$replacers = Import-Csv c:\temp\replaceSource.csv
gc c:\temp\aip.xml | ForEach-Object {
$output = $_
foreach ($r in $replacers) {
$output = $output -replace $r.ReplaceWhat, $r.ReplaceTo
}
#the output has to be appended, not to rewrite everything
return $output | Out-File c:\temp\report3.xml -Append
}
Content of replaceSource.csv looks like:
ReplaceWhat,ReplaceTo
192.168.1.1,server1
192.168.1.20,SERVER2
Note the headers
I have a powershell script to find particular instances and then export them to CSV. Here's an example of the way the code works
$items = "Hello Tim", "Hola Bob", "Hello Susan"
$filter = $items | Select-String -Pattern "Hello"
$filter | Select-Object Line, Matches | Export-Csv "C:\log.csv"
Invoke-Item "C:\log.csv"
When I run the Select-Object in PS, it's nicely formatted info like this:
However, when I export to CSV, it exports the whole object and writes it as the following string: System.Text.RegularExpressions.Match[]
How can I get it to export just the first match or a listing of all matches into a single field when writing to CSV?
Here is one way using a PSObject:
$items = "Hello Tim", "Hola Bob", "Hello Susan"
$filter = $items | Select-String -Pattern "Hello"
$filter | % {New-Object PSObject -property #{
Line = $_.Line
Matches = $_.Matches.Groups[0].Value}
} | Export-Csv "C:\log.csv" -NoTypeInformation
Quickly note that Matches is an array which may create issues exporting to a csv.
Try joining the array into a string with a chosen delimiter. I used "::" in my example.
$filter | Select Line, #{Expression={$_.Matches -join "::"}; Label="Matches"} | Export-Csv "C:\log.csv"
I am storing the content of a JSON output into a variable and the by using:
$j1| Select - Object -Property #{Label = "id"; Expression = {$_.id} | Export-CSV -Path C:\Temp\j1.csv -Delimiter "|" -notype
I am exporting the values to csv file.
My issue is that inside the PowerShell, I can see e.g.
{1}
{2,3}
{4}
{5,6}
However, after exporting to csv, the comma delimiter of object is missing. And I would like to have in csv too.
Could you please help me with my problem?
Thanks in advance
You can't have arrays as properties when you export to CSV. You need to join the IDs to a string before exporting it. Ex:
Select-Object -Property #{Label="id";Expression={$_.id -join ','}
