Write Text file data to csv - powershell

Question

Below is my data in text file
Volume ### Ltr Label Fs Type Size Status Info
---------- --- ----------- ----- ---------- ------- --------- --------
Volume 0 Z DVD-ROM 0 B No Media
Volume 1 System Rese NTFS Partition 500 MB Healthy System
Volume 2 C SYS NTFS Partition 99 GB Healthy Boot
Volume 3 S SWAP NTFS Partition 6141 MB Healthy Pagefile
Volume 4 D DATA NTFS Partition 199 GB Healthy
Volume 5 E bit locker NTFS Partition 9 GB Healthy
Volume 6 F test NTFS Partition 10 GB Healthy
I have to write it in csv. tried below code but not able to handle to Blank values. e.g. for first row Label,Fs,Info values are blank
$data = get-content -Path "C:\d.txt"
$result = switch -Regex ($data) {
'^\s*Volume \d' {
$disk,$status,$Label,$Fs,$Type,$size,$Stat,$Info = $_.Trim() -split '\s{2,}'
[PsCustomObject]#{
'Server' = $server
'Volume ###' = $disk
'Ltr' = $status
'Label' = $Label
'Fs' = $Fs
'Type' = $Type
'Size' = $size
'Status' = $Stat
'Info' = $Info
}
}
}
# output on console screen
$result | Format-Table -AutoSize
# output to CSV file
$result | Export-Csv -Path "C:\$server.csv" -NoTypeInformation -Append
Output is coming like
Server Volume ### Ltr Label Fs Type Size Status Info
------ ---------- --- ----- -- ---- ---- ------ ----
AxxxxxxxxxxxxxP Volume 0 Z DVD-ROM 0 B No Media
AxxxxxxxxxxxxxP Volume 1 System Rese NTFS Partition 500 MB Healthy System
AxxxxxxxxxxxxxP Volume 2 C SYS NTFS Partition 99 GB Healthy Boot
AxxxxxxxxxxxxxP Volume 3 S SWAP NTFS Partition 6141 MB Healthy Pagefile
AxxxxxxxxxxxxxP Volume 4 D DATA NTFS Partition 199 GB Healthy
AxxxxxxxxxxxxxP Volume 5 E bit locker NTFS Partition 9 GB Healthy
AxxxxxxxxxxxxxP Volume 6 F test NTFS Partition 10 GB Healthy
Please let me know how to handle the spaces or any other way I can write it to csv

this is what I am trying to do
$server = $env:COMPUTERNAME
# Start by reading in the table
# Replace this statement with `
$lines = Get-Content "c:\d.txt"
$lines = $lines -split '\r?\n'
# Assign the first two lines to separate variables
$header, $guardRails, $lines = $lines
# Split the header into individual column names
$columnNames = #(
$header.Trim() -split '\s{2,}' |ForEach-Object Trim
)
# Use regex to match all the individual `---` sequences, grab their offset + length
$columnOffsets = #(
[regex]::Matches($guardRails, '(?<!-)-+(?!-)') |Select Index,Length
)
# Parse the data based on the offsets located above
foreach($line in $lines){
# Prepare a dictionary to hold the column values, add the Server property straight away
$properties = [ordered]#{
Server = $server
}
# Now we just need to iterate over the lists of column headers and extract the corresponding substring from the line
for($i = 0; $i -lt $columnNames.Length; $i++){
# Grab the column name and offset
$propertyName = $columnNames[$i]
$offset = $columnOffsets[$i]
# Grab the substring corresponding to the column
$propertyValue = $line.Substring($offset.Index, $offset.Length).Trim()
# Add the information to our property dictionary
$properties[$propertyName] = $propertyValue
}
# Output a new object based on the properties we grabbed from the column data
[pscustomobject]$properties
# output on console screen
$properties | Format-Table -AutoSize
# output to CSV file
$properties | Export-Csv -Path "C:\$server.csv" -NoTypeInformation -Append
}

Answer 1

Use the line below the header ( ---------- --- -----------...) to detect at which offsets to parse data for a specific column name:
# Start by reading in the table
# Replace this statement with `$lines = Get-Content .\path\to\file.txt` in your script
$lines = #'
