Import csv into excel and specify cell format - excel

I am trying to import multiple csv files into their own tabs in 1 excel workbook. I am having an issue with long number fields being displayed as exponential data and changing the last digit to 0. For example I have a 16 digit account number (1234567890123456) it is being displayed in excel as an exponential number (1.23457E+15). When I look at the actual number in the cell it is (1234567890123450). I assume if I make the column text before I bring it in, it will work, but I'm not sure how to do that. Here is my code.
$excel = New-Object -ComObject excel.application
$excel.visible = $False
$excel.displayalerts=$False
$workbook = $excel.workbooks.add()
$sheets = $workbook.sheets
$sheetCount = $Sheets.Count
$mySheet = 1
$mySheetName = "Sheet" + $mySheet
$s1 = $sheets | where {$_.name -eq $mySheetName }
$s1.Activate()
If($sheetCount -gt 1)
{
#Delete other Sheets
$Sheets | ForEach
{
$tmpSheetName = $_.Name
$tmpSheet = $_
If($tmpSheetName -ne "Sheet1"){$tmpSheet.Delete()}
}
}
#import csv files
$files = dir -Path $csvDir*.csv
ForEach($file in $files){
If($mySheet -gt 1){$s1 = $workbook.sheets.add()}
$s1.Name = $file.BaseName
$s1.Activate()
$s1Data = Import-Csv $file.FullName
$s1data | ConvertTo-Csv -Delimiter "`t" -NoTypeInformation | Clip
$s1.cells.item(1,1).Select()
$s1.Paste()
$mySheet ++
if (test-path $file ) { rm $file }
}
$workbook.SaveAs($excelTMGPath)
$workbook.Close()
$workbook = $null
#$excel.quit()
while ([System.Runtime.InteropServices.Marshal]::FinalReleaseComObject($excel)) {}
$excel = $null

Try
If $s1 is pointed correctly,
$s1.cells.item(1,1).NumberFormat="#"
If that does not work, use NumberFormat where necessary. Use the format you prefer.
Change the name of your file extension from .csv to .txt. Adjust your filename in the code,
$files = dir -Path $csvDir*.txt

How to use powershell to select range and dump that to csv file

Actually, this is a version of question here:
How to use powershell to select and copy columns and rows in which data is present in new workbook.
The goal is to grab certain columns from multiple Excel workbooks and dump everything to one csv file. Columns are always the same.
I'm doing that manually:
$xl = New-Object -ComObject Excel.Application
$xl.Visible = $false
$xl.DisplayAlerts = $false
$counter = 0
$input_folder = "C:\Users\user\Documents\excelfiles"
$output_folder = "C:\Users\user\Documents\csvdump"
Get-ChildItem $input_folder -File |
Foreach-Object {
$counter++
$wb = $xl.Workbooks.Open($_.FullName, 0, 1, 5, "")
try {
$ws = $wb.Worksheets.item('Calls') # => This specific worksheet
$rowMax = ($ws.UsedRange.Rows).count
for ($i=1; $i -le $rowMax-1; $i++) {
$newRow = New-Object -Type PSObject -Property #{
'Type' = $ws.Cells.Item(1+$i,1).text
'Direction' = $ws.Cells.Item(1+$i,2).text
'From' = $ws.Cells.Item(1+$i,3).text
'To' = $ws.Cells.Item(1+$i,4).text
}
$newRow | Export-Csv -Path $("$output_folder\$ESO_Output") -Append -noType -Force
}
}
} catch {
Write-host "No such workbook" -ForegroundColor Red
# Return
}
}
Question:
This works, but is extremely slow because Excel has to select every cell, copy that, then Powershell has to create array and save row by row in output csv file.
Is there a method to select a range in Excel (number of columns times ($ws.UsedRange.Rows).count), cut header line and just append this range (array?) to csv file to make everything much faster?
So that's the final solution
Script is 22 times faster!!! than original solution.
Hope somebody will find that useful :)
PasteSpecial is to filter out empty rows. There is no need to save them into csv
$xl = New-Object -ComObject Excel.Application
$xl.Visible = $false
$xl.DisplayAlerts = $false
$counter = 0
$input_folder = "C:\Users\user\Documents\excelfiles"
$output_folder = "C:\Users\user\Documents\csvdump"
Get-ChildItem $input_folder -File |
Foreach-Object {
$counter++
try {
$new_ws1 = $wb.Worksheets.add()
$ws = $wb.Worksheets.item('Calls')
$rowMax = ($ws.UsedRange.Rows).count
$range = $ws.Range("A1:O$rowMax")
$x = $range.copy()
$y = $new_ws1.Range("A1:O$rowMax").PasteSpecial([System.Type]::Missing,[System.Type]::Missing,$true,$false)
$wb.SaveAs("$($output_folder)\$($_.Basename)",[Microsoft.Office.Interop.Excel.XlFileFormat]::xlCSVWindows)
} catch {
Write-host "No such workbook" -ForegroundColor Red
# Return
}
}
$xl.Quit()
Part above will generate a bunch of csv files.
Part below will read these files in separate loop and combine them together into one.

Powershell using ImportExcel to delete rows

I am trying to delete rows of data from an Excel file using the ImportExcel module.
I can open the file, find the the data I wish to delete and the DeleteRow command works on a hardcoded value however does not appear to work on a variable...any ideas?
# Gets ImportExcel PowerShell Module
if (-not(Get-Module -ListAvailable -Name ImportExcel)) {
Find-module -Name ImportExcel | Install-Module -Force
}
# Open Excel File
$excel = open-excelpackage 'C:\temp\input.xlsx'
#Set Worksheet
$ws = $excel.Workbook.Worksheets["Sheet1"]
#Get Row Count
$rowcount = $ws.Dimension.Rows
#Delete row if Cell in Column 15 = Yes
for ($i = 2; $i -lt $rowcount; $i++) {
$cell = $ws.Cells[$i, 15]
if ($cell.value -eq "Yes") {
$ws.DeleteRow($i)
}
}
#Save File
Close-ExcelPackage $excel -SaveAs 'C:\Temp\Output.xlsx'
You should reverse the loop and go from bottom to top row. As you have it, by deleting a row, the index of the ones below that is changed and your for ($i = 2; $i -lt $rowcount; $i++) {..} will skip over.
You can also do this without the ImportExcel module if you have Excel installed:
$file = 'C:\Temp\input.xlsx'
$excel = New-Object -ComObject Excel.Application
$excel.Visible = $false
# open the Excel file
$workbook = $excel.Workbooks.Open($file)
$sheet = $workbook.Worksheets.Item(1)
# get the number of rows in the sheet
$rowMax = $sheet.UsedRange.Rows.Count
# loop through the rows to test if the value in column 15 is "Yes"
# do the loop BACKWARDS, otherwise the indices will change on every deletion.
for ($row = $rowMax; $row -ge 2; $row--) {
$cell = $sheet.Cells[$row, 15].Value2
if ($cell -eq 'Yes') {
$null = $sheet.Rows($row).EntireRow.Delete()
}
}
# save and exit
$workbook.SaveAs("C:\Temp\Output.xlsx")
$excel.Quit()
# clean up the COM objects used
$null = [System.Runtime.Interopservices.Marshal]::ReleaseComObject($sheet)
$null = [System.Runtime.Interopservices.Marshal]::ReleaseComObject($workbook)
$null = [System.Runtime.Interopservices.Marshal]::ReleaseComObject($excel)
[System.GC]::Collect()
[System.GC]::WaitForPendingFinalizers()

Merge content of multiple Excel files into one using PowerShell

I have multiple Excel files with different names in path.
e.g. C:\Users\XXXX\Downloads\report
Each file has a fixed number of columns.
e.g. Date | Downtime | Response
I want to create a new Excel file with merge of all Excel data. New column should be added with client name in which i want to enter file name. Then each Excel file data append below one by one.
e.g. Client name | Date | Downtime | Response
Below code can able to append all excel data but now need to add Client name column.
$path = "C:\Users\XXXX\Downloads\report"
#Launch Excel, and make it do as its told (supress confirmations)
$Excel = New-Object -ComObject Excel.Application
$Excel.Visible = $True
$Excel.DisplayAlerts = $False
$Files = Get-ChildItem -Path $path
#Open up a new workbook
$Dest = $Excel.Workbooks.Add()
#Loop through files, opening each, selecting the Used range, and only grabbing the first 5 columns of it. Then find next available row on the destination worksheet and paste the data
ForEach($File in $Files)
{
$Source = $Excel.Workbooks.Open($File.FullName,$true,$true)
If(($Dest.ActiveSheet.UsedRange.Count -eq 1) -and ([String]::IsNullOrEmpty($Dest.ActiveSheet.Range("A1").Value2)))
{
#If there is only 1 used cell and it is blank select A1
[void]$source.ActiveSheet.Range("A1","E$(($Source.ActiveSheet.UsedRange.Rows|Select -Last 1).Row)").Copy()
[void]$Dest.Activate()
[void]$Dest.ActiveSheet.Range("A1").Select()
}
Else
{
#If there is data go to the next empty row and select Column A
[void]$source.ActiveSheet.Range("A2","E$(($Source.ActiveSheet.UsedRange.Rows|Select -Last 1).Row)").Copy()
[void]$Dest.Activate()
[void]$Dest.ActiveSheet.Range("A$(($Dest.ActiveSheet.UsedRange.Rows|Select -last 1).row+1)").Select()
}
[void]$Dest.ActiveSheet.Paste()
$Source.Close()
}
$Dest.SaveAs("$path\Merge.xls")
$Dest.close()
$Excel.Quit()
Suggest any effective way to do this. Please provide links if available.
Convert XLS to XLSX :
$xlFixedFormat = [Microsoft.Office.Interop.Excel.XlFileFormat]::xlWorkbookDefault
$excel = New-Object -ComObject excel.application
$excel.visible = $true
$folderpath = "C:\Users\xxxx\Downloads\report\*"
$filetype ="*xls"
Get-ChildItem -Path $folderpath -Include $filetype |
ForEach-Object `
{
$path = ($_.fullname).substring(0,($_.FullName).lastindexOf("."))
"Converting $path to $filetype..."
$workbook = $excel.workbooks.open($_.fullname)
$workbook.saveas($path, $xlFixedFormat)
$workbook.close()
}
$excel.Quit()
$excel = $null
[gc]::collect()
[gc]::WaitForPendingFinalizers()
If you are willing to use the external module Import-Excel, you could simply loop through the files like so:
$report_directory = ".\reports"
$merged_reports = #()
# Loop through each XLSX-file in $report_directory
foreach ($report in (Get-ChildItem "$report_directory\*.xlsx")) {
# Loop through each row of the "current" XLSX-file
$report_content = foreach ($row in Import-Excel $report) {
# Create "custom" row
[PSCustomObject]#{
"Client name" = $report.Name
"Date" = $row."Date"
"Downtime" = $row."Downtime"
"Response" = $row."Response"
}
}
# Add the "custom" data to the results-array
$merged_reports += #($report_content)
}
# Create final report
$merged_reports | Export-Excel ".\merged_report.xlsx"
Please note that this code is not optimized in terms of performance but it should allow you to get started

Passing CSV to Excel Workbook (Not From File)

I have a folder of CSV files that contain log entries. For each entry of the CSV, if the Risk property is not Low and not None then I put it in an accumulation CSV object. From there, I want to import it into an Excel Workbook directly WITHOUT having to save the CSV to file.
$CSVPaths = (Split-Path $PSCommandPath)
$AccumulateExportPath = (Split-Path $PSCommandPath)
$FileName="Accumulate"
$Acc=#()
Foreach ($csv in (Get-ChildItem C:\Scripts\Nessus\Sheets |? {$_.Extension -like ".csv" -and $_.BaseName -notlike "$FileName"}))
{
$Content = Import-CSV $csv.FullName
Foreach ($Log in $Content)
{
If ($Log.Risk -ne "None" -and $Log.Risk -ne "Low")
{
$Acc+=$Log
}
}
}
$CSV = $ACC |ConvertTo-CSV -NoTypeInformation
Add-Type -AssemblyName Microsoft.Office.Interop.Excel
$Script:Excel = New-Object -ComObject Excel.Application
$Excel.Visible=$True
#$Excel.Workbooks.OpenText($CSV) What should replace this?
Is there a Method like OpenText() that lets me pass a CSV object instead of a filepath to a CSV file or am I going to have to write my own conversion function?
Interesting question. I'm not aware of a method that allows you to pass a CSV Object.
However, if your result CSV is not too big and you are using PowerShell 5.0+ you could convert the object to a string and leverage Set-Clipboard (more info)
$headers = ($csv | Get-Member | Where-Object {$_.MemberType -eq "NoteProperty"}).Name
$delim = "`t"
# headers
foreach($header in $headers){
$myString += $header + $delim
}
# trim delimiter at the end, and add new line
$myString = $myString.TrimEnd($delim)
$myString = $myString + "`n"
# loop over each line and repeat
foreach($line in $csv){
foreach($header in $headers){
$myString += $line.$header + $delim
}
$myString = $myString.TrimEnd($delim)
$myString = $myString + "`n"
}
# copy to clipboard
Set-Clipboard $myString
# paste into excel from clipboard
$Excel.Workbooks.Worksheets.Item(1).Paste()
Here is another way to create an Excel spreadsheet from PowerShell without writing a .csv file.
$dirs = 'C:\src\t', 'C:\src\sql'
$records = $()
$records = foreach ($dir in $dirs) {
Get-ChildItem -Path $dir -File '*.txt' -Recurse |
Select-Object #{Expression={$_.FullName}; Label="filename"}
}
#open excel
$excel = New-Object -ComObject excel.application
$excel.visible = $false
#add a default workbook
$workbook = $excel.Workbooks.Add()
#remove worksheet 2 & 3
$workbook.Worksheets.Item(3).Delete()
$workbook.Worksheets.Item(2).Delete()
#give the remaining worksheet a name
$uregwksht = $workbook.Worksheets.Item(1)
$uregwksht.Name = 'File Names'
# Start on row 1
$i = 1
# the .appendix to $record refers to the column header in the csv file
foreach ($record in $records) {
$excel.cells.item($i,1) = $record.filename
$i++
}
#adjusting the column width so all data's properly visible
$usedRange = $uregwksht.UsedRange
$usedRange.EntireColumn.AutoFit() | Out-Null
#saving & closing the file
$outputpath = Join-Path -Path $Env:USERPROFILE -ChildPath "desktop\exceltest.xlsx"
$workbook.SaveAs($outputpath)
$excel.Quit()

Merging CSV Files into a XLSX with Tabs

I currently have 5 Registry CSV files which are created during a PowerShell script:
HKCC
HKCR
HKCU
HKLM
HKU
I need these CSV files to open at the end of the script however would like if all of them were contained within one XLSX file with 5 different headings
Is there a way to combine the files through PowerShell?
I understand how to get the data of the CSV files but don't understand how to merge them or convert. Some of the variables I believe which may be helpful.
$Date = Get-Date -Format "d.MMM.yyyy"
$DIR = $WPFlistview.Selecteditem.Ransomware
$path = "F:\Registry_Export\Results\$DIR\$Date\*"
$csvs = Get-ChildItem $path -Include *.csv
$output = "F:\Registry_Export\Results\$DIR\$Date\Results.Xlsx"
Paths to the CSV files if needed:
F:\Registry_Export\Results\$DIR\$Date\HKCR.CSV
F:\Registry_Export\Results\$DIR\$Date\HKCU.CSV
F:\Registry_Export\Results\$DIR\$Date\HKLM.CSV
F:\Registry_Export\Results\$DIR\$Date\HKU.CSV
F:\Registry_Export\Results\$DIR\$Date\HKCC.CSV
This is what I have tried prior. However, it completly scrambles my data into the wrong lines and cells:
function MergeCSV {
$Date = Get-Date -Format "d.MMM.yyyy"
$DIR = $WPFlistview.Selecteditem.Ransomware
$path = "F:\Registry_Export\Results\$DIR\$Date\*"
$csvs = Get-ChildItem $path -Include *.csv
$y = $csvs.Count
Write-Host "Detected the following CSV files: ($y)"
foreach ($csv in $csvs) {
Write-Host " "$csv.Name
}
$outputfilename = "Final Registry Results"
Write-Host Creating: $outputfilename
$excelapp = New-Object -ComObject Excel.Application
$excelapp.SheetsInNewWorkbook = $csvs.Count
$xlsx = $excelapp.Workbooks.Add()
$sheet = 1
foreach ($csv in $csvs) {
$row = 1
$column = 1
$worksheet = $xlsx.Worksheets.Item($sheet)
$worksheet.Name = $csv.Name
$file = (Get-Content $csv)
foreach ($line in $file) {
$linecontents = $line -split ',(?!\s*\w+")'
foreach ($cell in $linecontents) {
$worksheet.Cells.Item($row,$column) = $cell
$column++
}
$column = 1
$row++
}
$sheet++
}
$output = "F:\Registry_Export\Results\$DIR\$Date\Results.Xlsx"
$xlsx.SaveAs($output)
$excelapp.Quit()
}

So, using the Excel.Application ComObject still, what I would suggest is loading each CSV as a CSV, not using Get-Content like you are. Then use the ConvertTo-CSV cmdlet, specifying to use tab as the delimiter, and copy that to the clipboard. Then just paste into Excel, and it will paste in fairly nicely. You may want to adjust column size, but the data will show up just as you would expect it to. I would also use a For loop instead of a ForEach loop, since Excel plays nice with numbers for the tabs (though it is 1 based instead of PowerShell's 0 base). Here's what I would end up with after making those modifications:
function MergeCSV {
$Date = Get-Date -Format "d.MMM.yyyy"
$DIR = $WPFlistview.Selecteditem.Ransomware
$path = "F:\Registry_Export\Results\$DIR\$Date\*"
$csvs = Get-ChildItem $path -Include *.csv
$y = $csvs.Count
Write-Host "Detected the following CSV files: ($y)"
Write-Host " "$csvs.Name"`n"
$outputfilename = "Final Registry Results"
Write-Host Creating: $outputfilename
$excelapp = New-Object -ComObject Excel.Application
$excelapp.SheetsInNewWorkbook = $csvs.Count
$xlsx = $excelapp.Workbooks.Add()
for($i=1;$i -le $y;$i++) {
$worksheet = $xlsx.Worksheets.Item($i)
$worksheet.Name = $csvs[$i-1].Name
$file = (Import-Csv $csvs[$i-1].FullName)
$file | ConvertTo-Csv -Delimiter "`t" -NoTypeInformation | Clip
$worksheet.Cells.Item(1).PasteSpecial()|out-null
}
$output = "F:\Registry_Export\Results\$DIR\$Date\Results.Xlsx"
$xlsx.SaveAs($output)
$excelapp.Quit()
}
You could use ImportExcel by Doug Finke And then replace your Export-CSV in the original script with Export-Excel -WorksheetName
Install-Module ImportExcel
Export-Excel "F:\Registry_Export\Results\$DIR\$Date\Results.xlsx" -worksheetname "HKCR"
Export-Excel "F:\Registry_Export\Results\$DIR\$Date\Results.xlsx" -worksheetname "HKCU"
