I'm having trouble getting my head around how to take the two "properties" of each object within a json and output them into a csv. The two properties are "name" and "jobtitle" and I figure there should be a way to extract them.
$employees= ConvertFrom-Json $json
foreach ($person in $employees.information) {
# $person.name $person.jobtitle
}
No need for a loop, that should be bread-and-butter PowerShell territory. Feed the collection to a pipeline, use Select-Object to pick out the properties you care about, and then feed the pipeline to Export-CSV which handles the CSV header row, putting them on the same line, putting commas between them, quoting, etc.
$employees = ConvertFrom-Json $json
$employees.information | Select-Object name, jobtitle | Export-CSV -Path out.csv -NoTypeInformation
The only weird bit is -NoTypeInformation which stops it from putting PowerShell-specific markers for Integer/String/etc. types in the CSV, things which Excel (for example) won't read.
e.g. three objects with X,Y,Z properties - select just X and Z, and make them a CSV:
PS C:\> $Things = #(
[PSCustomObject]#{X=1; Y=2; Z=3}
,[PSCustomObject]#{X=4; Y=5; Z=6}
,[PSCustomObject]#{X=7; Y=8; Z=9}
)
$Things | Select-Object X,Z | ConvertTo-Csv -NoTypeInformation
"X","Z"
"1","3"
"4","6"
"7","9"

Hi I have a script that reads a csv file, creates a json file, checks the users in the file against a service, then i get the result as a json file.
I take that result and finds the users i csv file and creates a new file.
I do that with a where-object
But i need to add some extra values on every user before i export it to csv
This is my 2 lines for finding users and then export
$matches = $users | where-object { $_.number -in $response.allowedItemIds } | Select-Object -Property Number,Surname,Forename,Emailaddress
$matches | Export-Csv -path $Saved$savefile -NoTypeInformation -Append
Is that possible or do i need to do a for each?
Cheers
Assuming I've interpretted your question correctly, you should be able to use PowerShell's Calculated Properties for this purpose.
For example, if you wanted to add a field called "Date" and set the current Date/Time to each user row, you could do the following:
$matches = $users | where-object { $_.number -in $response.allowedItemIds } | Select-Object -Property Number,Surname,Forename,Emailaddress, #{Name="Date";Expression={Get-Date}}
The Expression value can either be a static value such as "StaticValue", a variable such as $i (useful if used as part of a loop, for example) or more complex value that is returned from other cmdlets (as in my example above)
PowerShell newbie here,
I need to:
Get text files in recursive local directories that have a common string, students.txt in them.
Get another string, gc.student="name,name" in the resulting file set from #1 and get the name(s).
Put the filename from #1, and just the name,name from #2 (not gc.student="") into a hashtable where the filename is paired with its corresponding name,name.
Output the hashtable to an Excel spreadsheet with 2 columns: File and Name.
I've figured out, having searched and learned here and elsewhere, how to output #1 to the screen, but not how to put it into a hashtable with #2:
$documentsfolder = "C:\records\"
foreach ($file in Get-ChildItem $documentsfolder -recurse | Select String -pattern "students.txt" ) {$file}
I'm thinking to get name in #2 I'll need to use a RegEx since there might only be 1 name sometimes.
And for the output to Excel, this: | Export-Csv -NoType output.csv
Any help moving me on is appreciated.
I think this should get you started. The explanations are in the code comments.
# base directory
$documentsfolder = 'C:\records\'
# get files with names ending with students.txt
$files = Get-ChildItem $documentsfolder -recurse | Where-Object {$_.Name -like "*students.txt"}
# process each of the files
foreach ($file in $files)
{
$fileContents = Get-Content $file
$fileName = $file.Name
#series of matches to clean up different parts of the content
#first find the gc.... pattern
$fileContents = ($fileContents | Select-String -Pattern 'gc.student=".*"').Matches.Value
# then select the string with double quotes
$fileContents = ($fileContents | Select-String '".*"').Matches.Value
# then remove the leading and trailing double quotes
$fileContents = $fileContents -replace '^"','' -replace '"$',''
# drop the objects to the pipeline so that you can pipe it to export-csv
# I am creating custom objects so that your CSV headers will nave nice column names
Write-Output [pscustomobject]#{file=$fileName;name=$fileContents}
} | Export-Csv -NoType output.csv
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.

#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 $output | Out-File c:\temp\report3.xml -Append
}
Content of replaceSource.csv looks like:
ReplaceWhat,ReplaceTo
192.168.1.1,server1
192.168.1.20,SERVER2
Note the headers
I am trying to take a filename such as: John_Doe_E_DOB_1/1/46_M(This is the gender)_ID_0000000_IMG_FileName_Date-of-File_1/1/15_Doc-page-1 And create a CSV file to open in Excel with column headers for: Last Name, First Name, MI, ID No, File Name, Date of File along with doc type. Here's my code so far:
Get-ChildItem -Path C:\Users\name\desktop\test -Recurse | ForEach-Object {$_ | add-member -name "Owner" -membertype noteproperty -value (get-acl $_.fullname).owner -passthru} | Sort-Object fullname | Select BaseName,Name,Owner | Export-Csv -Force -NoTypeInformation C:\Users\name\desktop\test\thing.csv
All this is doing is dropping that really long file name in at the top, and then adding the ext at the end in another column. Example:
John_Doe_E_DOB_1/1/46_M(This is the gender)_ID_0000000_IMG_FileName_Date-of-File_1/1/15_Doc-page-1 Would be in column 1 and
John_Doe_E_DOB_1/1/46_M(This is the gender)_ID_0000000_IMG_FileName_Date-of-File_1/1/15_Doc-page-1.txt <----- Would be the only difference in column 2
How can I split this up for over a million files, all different lengths, and sizes, and get it to break up into the categories listed above? All help would be greatly appreciated.
I would replace the Select stage of your pipeline with a call to a filter function like this:
filter GenObj {
$parts = $_.FullName.Split('_')
new-object pscustomobject -property #{
Owner = (get-acl $_.fullname).owner
FirstName = $parts[0]
LastName = $parts[1]
MiddleInitial = $parts[2]
# Fill in the rest
}
}
Get-ChildItem -Path C:\Users\name\desktop\test -Recurse |
Sort-Object fullname |
GenObj |
Export-Csv -Force -NoTypeInformation C:\Users\name\desktop\test\thing.csv
This will create a new custom object with all the properties on it that correspond to the parts of the filename you want to extract.
This string splitting approach may not work depending on how you handle names with no middle initial.
Also be aware that if you are processing a million files, the use of Sort-Object will cause every single FileInfo object (one for every file) to get buffered in memory so the sort can be performed. You may likely run out of memory and the command will fail. I would consider removing Sort-Object in this scenario.
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 ','}
