Convert TXTto CSV - excel

Question

I'm working on a project where I need to take a text file and make it an excel file. So far what I've come up with is this.
cls
Remove-Item -path D:\Users\zabin\OneDrive\Desktop\ITS3410\WEEK8\MainWarehouse.csv
Add-Content -path D:\Users\zabin\OneDrive\Desktop\ITS3410\WEEK8\MainWarehouse.csv -Value '"Part_Number","Cost","Price"'
$csvPath = 'D:\Users\zabin\OneDrive\Desktop\ITS3410\WEEK8\MainWarehouse.csv'
#region Excel Test
If (test-path HKLM:SOFTWARE\Classes\Word.Application) {
Write-host "Microsoft Excel installed"
} else {
Write-host "Microsoft Excel not installed"
}
#endregion
#region Patterns
$mainpattern1 = '(?<Partnumber>\d*\s*\w*,)(?<Cost>\d*.\d*),(?<Price>\d*.\d*)'
$mainpattern2 = '(?<Part_number>\d*-\d*-\d*),(?<Cost>\d*.\d*),(?<Price>\d*.\d*)'
#endregion
get-Content 'D:\Users\zabin\OneDrive\Desktop\ITS3410\WEEK8\MainWarehouse.csv' | #grabs the content
Select-String -Pattern $mainpattern1, $mainpattern2 | #selects the patterns
Foreach-Object {
$Part_Number, $Cost, $Price = $_.Matches[0].Groups['Part_number', 'Cost','Price']
[PSCustomObject] #{
part_number = $Part_Number
Cost = $Cost
Price = $Price
}
$objResults | Export-Csv -Path $csvPath -NoTypeInformation -Append
}
some sample data is here
00001143 SP,136.41,227.35
00001223 SP,48.66,81.10
00001236 SP,149.72,249.53
0001-0003-00,100.95,168.25
00015172 W,85.32,142.20
I'm getting the file created and the header values are correct but I'm not sure how to get the values to import.

Continuing from my comment... with the resources and a simple example.
Find-Module -Name '*excel*' | Format-Table -AutoSize

MSExcel will read properly formatted CSV's natively. So, to convert to a true XLS file, use PowerShell, MSOffice COM to open MSExcel with the CSV file, then save it as an XLS format.
$FileName = "$env:temp\Report"
Get-Process |
Export-Csv -UseCulture -Path "$FileName.csv" -NoTypeInformation -Encoding UTF8
$excel = New-Object -ComObject Excel.Application
$excel.Visible = $true
$excel.Workbooks.Open("$FileName.csv").SaveAs("$FileName.xlsx",51)
$excel.Quit()
explorer.exe "/Select,$FileName.xlsx"
Your use case is of course as noted:
Import-Csv -Path 'D:\temp\book1.txt' -header Title, Author
Then using COM as noted above.

Answer 2

I ended up solving this after I asked the question I had alot of flaws in this code
Add-Content -path D:\Users\zabin\OneDrive\Desktop\ITS3410\WEEK8\MainWarehouse.csv -Value '"Part_Number","Cost","Price"'
$csvPath = 'D:\Users\zabin\OneDrive\Desktop\ITS3410\WEEK8\MainWarehouse.csv'
#region Excel Test
If (test-path HKLM:SOFTWARE\Classes\Excel.Application) {#these next few lines will check if excel is installed on the system
Write-host "Microsoft Excel installed"
} else {
Write-host "Microsoft Excel not installed"
}
#endregion
#region Patterns
$mainpattern1 = '(?<Part_number>\d*\s*\w*),(?<Cost>\d*.\d*),(?<Price>\d*.\d*)'#These two line will use REGEX to help seperate the data
$mainpattern2 = '(?<Part_number>\d*-\d*-\d*),(?<Cost>\d*.\d*),(?<Price>\d*.\d*)'
#endregion
get-Content 'D:\Users\zabin\OneDrive\Desktop\ITS3410\WEEK8\Main.rtf' | #grabs the content
Select-String -Pattern $mainpattern2, $mainpattern1 | #selects the patterns
Foreach-Object {
$Part_number, $Cost, $Price = $_.Matches[0].Groups['Part_number', 'Cost','Price'] #Gets the groups of a call to select-string
$results = [PSCustomObject] #{#the list here is what i use to seperate the data onto the CSV file
part_number = $Part_Number
Cost = $Cost
Price = $Price
}
$results | Export-Csv -Path $csvPath -NoTypeInformation -Append #moves the results to the CSV file
}
