I need to import a csv, select a string and change some part of it's value to $env:username. I think I have to work with select-string to get the string, but i'm stuck with changing the value. Or is it possible to write $env:username directly into the csv? I wasn't able to do it. also, the CSV should stay the way it is, only the current powershell session needs the correct string
CSV looks like this, userhome should be replaced by $env:username:
Test Test2
----- -----
Hi C:\user\userhome
something C:\test\install
hello C:\windows
Thats what i tried but I'm not successfull.
$test.Test2 | sls userhome -replace ($env:username)
another approach:
sls ($test.Test2).value -replace ("userhome",$env:username)
EDIT: This is the whole command where this csv is needed - just for information:
$Drives = Import-CSV .\NetworkDrives.csv -Delimiter ';' | ? {(($_.Group).split(',') -contains $UserOU) -and (!(Test-Path $_.Letter))} | % { #Do Stuff }
I'm glad that PetSerAl's answer in the comments worked for you. Personally I think it may have been simpler to use Get-Content, run a -Replace on that, and then pipe to ConvertFrom-CSV instead of Import-CSV.
$Drives= (Get-Content .\NetworkDrives.csv) -Replace "userhome",$env:username | ConvertFrom-CSV -Delimiter ';' | ? {(($_.Group).split(',') -contains $UserOU) -and (!(Test-Path $_.Letter))} | % { #Do Stuff }

I've created the following small script to remove 2++ strings from a CSV.
Each row is a log of a given person and a answer they give.
The CSV has X columns.
The column named FIRST identifies the person.
What I need to do is when I delete a row matching the answer, I also need to delete the person from the whole CSV if it had one of the two strings.
What I've made so far, removes the row of people having the answers but the person is still left in the overall CSV with other answers. I want to remove the person fully if the questions have been answered.
Can somebody help me out with making the addition or changes to make this happen?
INPUT File
FIRST,LAST,ADDR,ADDR2,GENDER,HOME,WORK

10007,JADE,BB,N/A,OMA,N/A,N/A

SCRIPT
$CSVfile = "C:\Temp\Test\Test.csv"
$CSVfile_filtered = "C:\Temp\Test\Test.csv"
$regex001 = "AA"
$regex002 = "BB"
$filterArray = #($regex001,$regex002)
Get-Content $CSVfile | Select-String -pattern $filterArray -notmatch | Set-Content $CSVfile_filtered
The file should then remove 10005, 10011 and both lines of 10007. But my version only removes one of the 10007 since it only matches one of the two patterns.
Using more of PowerShell's built-in cmdlets can make this a little easier to manage.
# Assuming searching only properties ADDR and ADDR2
$filter = 'AA','BB'
# Grouping by First and Last values to easily remove duplicates
# -match uses regex so | is needed for an OR of multiple items
Import-Csv Test.csv | Group-Object First,Last |
Where {!($_.Group.ADDR,$_.Group.ADDR2 -match ($filter -join '|'))} |
Foreach-Object Group |
Export-Csv output.csv -NoType
You would think strictly using text manipulation would be simpler, but it adds other scenarios to consider:
You will need to track users that have duplicate entries and potentially back track to remove them (if not grouping). This could require reading the file contents twice.
Your header row could match the string you want to filter so you will need to add it to the output if filtering removes it.
Keeping the scenarios above in mind, you can still use a grouping concept:
$filter = 'AA','BB'
$file = Get-Content Test.csv
# $file[0] is the header row
# -split string uses regex and splits at the second comma
# -split results' [0] element is First,Last values
$file[0],($file |
Select-Object -Skip 1 |
Group-Object {($_ -split '(?<=^[^,]*,[^,]*),')[0]} |
where {!($_.Group -match ($filter -join '|'))} |
Foreach-Object Group) | Set-Content output.csv
If I got it right you could do something like this:
$SearchPattern = 'AA', 'BB'
$INPUTCSV = #'
FIRST,LAST,ADDR,ADDR2,GENDER,HOME,WORK
1,N/A,N/A,N/A,N/A,BAF,N/A
10005,JAS,AA,N/A,,ZAV,N/A
10007,JADE,BB,N/A,OMA,N/A,N/A
10007,JADE,N/A,RAV,N/A,N/A,N/A
10011,KIAH,N/A,N/A,BALI,BB,N/A
'# | ConvertFrom-Csv
$ActualSearchPattern =
$INPUTCSV |
Where-Object {
$_.LAST -in $SearchPattern -or
$_.ADDR -in $SearchPattern -or
$_.ADDR2 -in $SearchPattern -or
$_.GENDER -in $SearchPattern -or
$_.HOME -in $SearchPattern -or
$_.Work -in $SearchPattern
} |
Select-Object -ExpandProperty FIRST
$INPUTCSV |
Where-Object -Property FIRST -NotIn -Value $ActualSearchPattern |
Format-Table -AutoSize
There might be more sophisticated or more elegant ways but I cannot think about one at the moment. ;-)
There is a nice PowerShell module you can use to manipulate the content of a csv or xlsx file: ImportExcel
This give you a lot of options to manipulate the sheets, columns etc.
I'm trying to get the output of two separate files although I'm stuck on the wild card or contains select-string search from file A (Names) in file B (name-rank).
The contents of file A is:
adam
george
william
assa
kate
mark
The contents of file B is:
12-march-2020,Mark-1
12-march-2020,Mark-2
12-march-2020,Mark-3
12-march-2020,william-4
12-march-2020,william-2
12-march-2020,william-7
12-march-2020,kate-54
12-march-2020,kate-12
12-march-2020,kate-44
And I need to match on every occurrence of the names after the '-' so my ordered output should look like this which is a combination of both files as the output:
mark
Mark-1
Mark-2
Mark-3
william
william-2
william-4
william-7
Kate
kate-12
kate-44

So far I only have the following and I'd be grateful for any pointers or assistance please.
import-csv (c:\temp\names.csv) |
select-string -simplematch (import-csv c:\temp\names-rank.csv -header "Date", "RankedName" | select RankedName) |
set-content c:\temp\names-and-ranks.csv
I imagine the select-string isn't going to be enough and I need to write a loop instead.
The data you give in the example does not give you much to work with, and the desired output is not that intuitive, most of the time with Powershell you would like to combine the data in to a much richer output at the end.
But anyway, with what is given here and what you want, the code bellow will get what you need, I have left comments in the code for you
$pathDir='C:\Users\myUser\Downloads\trash'
$names="$pathDir\names.csv"
$namesRank="$pathDir\names-rank.csv"
$nameImport = Import-Csv -Path $names -Header names
$nameRankImport= Import-Csv -Path $namesRank -Header date,rankName
#create an empty array to collect the result
$list=#()
foreach($name in $nameImport){
#get all the match names
$match=$nameRankImport.RankName -like "$($name.names)*"
#add the name from the First list
$list+=($name.names)
#if there are any matches, add them too
if($match){
$list+=$match
}
}
#Because its a one column string, Export-CSV will now show us what we want
$list | Set-Content -Path "$pathDir\names-and-ranks.csv" -Force
For this I would use a combination of Group-Object and Where-Object to first group all "RankedName" items by the name before the dash, then filter on those names to be part of the names we got from the 'names.csv' file and output the properties you need.
# read the names from the file as string array
$names = Get-Content -Path 'c:\temp\names.csv' # just a list of names, so really not a CSV
# import the CSV file and loop through
Import-Csv -Path 'c:\temp\names-rank.csv' -Header "Date", "RankedName" |
Group-Object { ($_.RankedName -split '-')[0] } | # group on the name before the dash in the 'RankedName' property
Where-Object { $_.Name -in $names } | # use only the groups that have a name that can be found in the $names array
ForEach-Object {
$_.Name # output the group name (which is one of the $names)
$_.Group.RankedName -join [environment]::NewLine # output the group's 'RankedName' property joined with a newline
} |
Set-Content -Path 'c:\temp\names-and-ranks.csv'
Output:
Mark
Mark-1
Mark-2
Mark-3

william-4
william-2

I have a directory on a server called 'servername'. In that directory, I have subdirectories whose name is a date. In those date directories, I have about 150 .csv file audit logs.
I have a partially working script that starts from inside the date directory, enumerates and loops through the .csv's and searches for a string in a column. Im trying to get it to export the row for each match then go on to the next file.
$files = Get-ChildItem '\\servername\volume\dir1\audit\serverbeingaudited\20180525'
ForEach ($file in $files) {
$Result = If (import-csv $file.FullName | Where {$_.'path/from' -like "*01May18.xlsx*"})
{
$result | Export-CSV -Path c:\temp\output.csv -Append}
}
What I am doing is searching the 'path\from' column for a string - like a file name. The column contains data that is always some form of \folder\folder\folder\filename.xls. I am searching for a specific filename and for all instances of that file name in that column in that file.
My issue is getting that row exported - export.csv is always empty. Id also like to start a directory 'up' and go through each date directory, parse, export, then go on to the next directory and files.
If I break it down to just one file and get it out of the IF it seems to give me a result so I think im getting something wrong in the IF or For-each but apparently thats above my paygrade - cant figure it out....
Thanks in advance for any assistance,
RichardX
The issue is your If block, when you say $Result = If () {$Result | ...} you are saying that the new $Result is equal what's returned from the if statement. Since $Result hasn't been defined yet, this is $Result = If () {$null | ...} which is why you are getting a blank line.
The If block isn't even needed. you filter your csv with Where-Object already, just keep passing those objects down the pipeline to the export.
Since it sounds like you are just running this against all the child folders of the parent, sounds like you could just use the -Recurse parameter of Get-ChildItem
Get-ChildItem '\\servername\volume\dir1\audit\serverbeingaudited\' -Recurse |
ForEach-Object {
Import-csv $_.FullName |
Where-Object {$_.'path/from' -like "*01May18.xlsx*"}
} | Export-CSV -Path c:\temp\output.csv
(I used a ForEach-Object loop rather than foreach just demonstrate objects being passed down the pipeline in another way)
Edit: Removed append per Bill_Stewart's suggestion. Will write out all entries for the the recursed folders in the run. Will overwrite on next run.
I don't see a need for appending the CSV file? How about:
Get-ChildItem '\\servername\volume\dir1\audit\serverbeingaudited\20180525' | ForEach-Object {
Import-Csv $_.FullName | Where-Object { $_.'path/from' -like '*01May18.xlsx*' }
} | Export-Csv 'C:\Temp\Output.csv' -NoTypeInformation
Assuming your CSVs are in the same format and that your search text is not likely to be present in any other columns you could use a Select-String instead of Import-Csv. So instead of converting string to object and back to string again, you can just process as strings. You would need to add an additional line to fake the header row, something like this:
$files = Get-ChildItem '\\servername\volume\dir1\audit\serverbeingaudited\20180525'
$result = #()
$result += Get-Content $files[0] -TotalCount 1
$result += ($files | Select-String -Pattern '01May18\.xlsx').Line
$result | Out-File 'c:\temp\output.csv'
In PowerShell I'm importing a CSV SAMTemp2 which will have a field called SO. Sometimes SO will be populated with "NW" and in these cases I just want to pull the field called ProdProj from the same line and replace the data in SO with the data in ProdProj then export it the data in that condition.
$RepNW = Import-Csv $SAMTemp2
foreach($d in $data){
If($d.SO -eq "NW"){($d.SO).Replace($d.ProdProj)}}
$RepNW | Export-Csv $SAMTemp -NoTypeInformation
I don't get an error, but this doesn't seem to do anything, either. Can anyone assist me, please?
Update
Per Matt below, I tried:
$RepNW = Import-Csv $SAMTemp2
foreach($d in $RepNW){
If($d.SO -eq "NW"){$d.SO = ($d.SO).Replace($d.ProdProj)}}
$RepNW | Export-Csv $SAMTemp -NoTypeInformation
But I'm not seeing any change. Any assistance is appreciated.
As LotPings pointed out in this line foreach($d in $data){, you haven't defined $data and it seems that you mean it to be foreach($d in $RepNW){
Secondly, rather than using Replace() you can just set one property to be equal to the other.
Last, this probably easiest to do all in the pipeline with ForEach-Object
Import-Csv $SAMTemp2 | ForEach-Object {
If($_.SO -eq "NW"){
$_.SO = $_.ProdProj
}
$_
} | Export-Csv $SAMTemp -NoTypeInformation
I'm using PowerShell To import a TAB separated file with headers. The generated file has a few empty strings "" on the end of first line of headers. PowerShell fails with an error:
"Cannot process argument because the
value of argument "name" is invalid.
Change the value of the "name"
argument and run the operation again"
because the header's require a name.
I'm wondering if anyone has any ideas on how to manipulate the file to either remove the double quotes or enumerate them with a "1" "2" "3" ... "10" etc.
Ideally I would like to not modify my original file. I was thinking something like this
$fileContents = Get-Content -Path = $tsvFileName
$firstLine = $fileContents[0].ToString().Replace('`t""',"")
$fileContents[0] = $firstLine
Import-Csv $fileContents -Delimiter "`t"
But Import-Csv is expecting $fileContents to be a path. Can I get it to use Content as a source?
You can either provide your own headers and ignore the first line of the csv, or you can use convertfrom-csv on the end like Keith says.
ps> import-csv -Header a,b,c,d,e foo.csv
Now the invalid headers in the file is just a row that you can skip.
-Oisin
If you want to work with strings instead use ConvertFrom-Csv e.g.:
PS> 'FName,LName','John,Doe','Jane,Doe' | ConvertFrom-Csv | Format-Table -Auto
FName LName
----- -----
John Doe
Jane Doe
I ended up needing to handle multiple instances of this issue. Rather than use the -Header and manually setting up each import instance I wrote a more generic method to apply to all of them. I cull out all of the `t"" instances of the first line and save the file to open as a $filename + _bak and import that one.
$fileContents = Get-Content -Path $tsvFileName
if( ([string]$fileContents[0]).ToString().Contains('""') )
{
[string]$fixedFirstLine = $fileContents[0].ToString().Replace('`t""',"")
$fileContents[0] = $fixedFirstLine
$tsvFileName = [string]::Format("{0}_bak",$tsvFileName
$fileContents | Out-File -FilePath $tsvFileName
}
Import-Csv $tsvFileName -Delimiter "`t"
My Solution if you have much columns :
$index=0
$ColumnsName=(Get-Content "C:\temp\yourCSCFile.csv" | select -First 1) -split ";" | %{
$index++
"Header_{0:d5}" -f $index
}
import-csv "C:\temp\yourCSCFile.csvv" -Header $ColumnsName
