Delete extra rows in an excel file with powershell? - excel

Question

I have been tasked to automate part of the logging process on a SPLA server owned by the company. My task is to date, archive, and remove the old files, then move onto a generating a report to be emailed to the department. This task is supposed to be ran at the end of every week.
I figured powershell would be the best option to complete this task. This is my first time working with powershell so I had a bit of learning to do.
My question:
Is it possible to loop through an excel worksheet and delete unused rows using this script?
My condition would be if there are two empty rows -> delete one row and keep going
I am taking info from the log and splitting it into a CSV then converting the CSV to an excel for formatting.
Sample of the Excel spreadsheet, others vary in excess rows between information
Get-ChildItem C:\ScriptsDirectory1\*.log | foreach{
$input = Get-Content $_.FullName #Initialize input
$a = Get-Date #Save the current date (for if/else wrapper)
#=============================================#
# File Name Changer #
#=============================================#
$x = $_.LastWriteTime.ToShortDateString() #Save a temp variable with the LastWriteTime and send it to a string
$new_folder_name = Get-Date $x -Format yyyy.MM.dd #Create a new folder that contains the string information
$des_path = "C:\Archive\ArchivedLogs\$new_folder_name" #Send the new folder to the archive directory
#=============================================#
$data = $input[1..($input.Length - 1)] #Initialize Array and set it to the length of the input file.
$maxLength = 0
$objects = ForEach($record in $data) { #Loop through each object within the array
$split = $record -split ": " #Split objects within array at the ": " string
If($split.Length -gt $maxLength){
$maxLength = $split.Length
}
$properties = #{}
For($i=0; $i -lt $split.Length; $i++) { #Adds the split information to the strings array
$properties.Add([String]($i+1),$split[$i])
}
New-Object -TypeName PSObject -Property $properties
}
$objects | format-table
$headers = [String[]](1..$maxLength)
$objects |
Select-Object $headers |
Export-Csv -NoTypeInformation -Path "C:\Archive\CSVReports\$new_folder_name.csv"#Export CSV path using the new folder name to prevent overwrite
if (test-path $des_path){ #Test if the path exists, and fill the directory with the file to be archived
move-item $_.fullname $des_path
} else {
new-item -ItemType directory -Path $des_path
move-item $_.fullname $des_path

# -[/] <-Complete -[] <- Incomplete
# -[] Archive or delete CSV Files

The following code worked to run through the program:
for($i = 350 ; $i -ge 0 ; $i--) {
If ($SPLA1wksht.Cells.Item($i, 1).Text-eq "") {
$Range = $SPLA1wksht.Cells.Item($i, 1).EntireRow
[void]$Range.Delete()
echo $i
}
If ($SPLA1wksht.Cells.Item($i, 2).Text-eq "") {
$Range = $SPLA1wksht.Cells.Item($i, 2).EntireRow
[void]$Range.Delete()
echo $i
}
If($i -eq 2){ break;}
}

This should be relatively straight forward
$file = C:\path\to\file.csv
$csv = Import-Csv $file
foreach($row in $csv) {
# logic to delete row
# $csv is an array, so you can could make the row = null to delete it
}
# spit out updated excel sheet
Export-Csv | $csv -NoTypeInformation
