Using Powershell to Delete Excel Rows

Question

Hi everyone.  Again, I am having trouble working with Excel via Powershell.  I am slowly learning my way around but cannot correctly utilize any information I may find that helps me get the correct results.  So far I am working on a project
at work that is automating the testing of our build process.  I am "borrowing" an excel sheet that I will save to my local machine to save as CSV.  However, before saving to CSV I need to remove the empty rows.  Unfortunately, the cells are
not really blank but still contain links to the server I pulled the workbook from.
I'm not sure what is easiest to do, but the "blanks" are within this range: A49:F320  and this is the range I'd like to delete.  The code I am currently working with is:
$Excel = new-object -comobject excel.application
$Excel.Visible = $False
$Workbook = $Excel.Workbooks.Open($BuildXLS)
$Worksheet = $Workbook.Worksheets.Item(1)
$i = 1
    If ($Worksheet.Cells.Item($i, 1).Value() -eq "  ") {
        $Range = $Worksheet.Cells.Item($i, 1).EntireRow
        $a = $Range.Delete()
        $i -= 1
    $i += 1
 Incidentally, mjolinor helped with an earlier issue parsing through the CSV.  It was only after looking at the output that I discovered my real issue is working with the Excel.
$data = import-csv $csv | Where-Object {$_.juris -ne " "}
#format Juris-Version results
foreach ($line in $data)
  if ($line.juris -eq 'US'){$line.Version = $FedVerNum}
   else {$line.Version = $ContentVer}
       write-output $line.juris$line.version | Out-File -Append "C:\1_JurisVersion.txt"
The output from that help session looks like:
US
$FedVerNum
State
$ContentVer
State
$ContentVer
Is there a away I can get this to read as
US $FedVerNum
state $ContentVer
state $ContentVer
state $ContentVer
Many thanks for the help and expertise!

The Excel constants are "magic" numbers that can be found in Excel via the Object Browser in the Visual Basic Editor.
There are several that I use all the time, so I made a list of the ones I use most often:
Const ForReading = 1
Const xlAscending = 1
Const xlGuess = 0
Const xlTopToBottom = 1
Const xlSortNormal = 0
Const xlCount = -4112
Const xlArea = 1
Const xlBar = 2
Const xlColumn = 3
Const xlLine = 4
Const xlPie = 5
Const xlRadar = -4151
Const xlXYScatter = -4169
Const xlCombination = -4111
Const xl3DArea = -4098
Const xl3DBar = -4099
Const xl3DColumn = -4100
Const xl3DLine = -4101
Const xl3DPie = -4102
Const xl3DSurface = -4103
Const xlDoughnut = -4120
Const xlPasteValuesAndNumberFormats = 12
Const xlpasteFormats = -4122
Const xlpasteValues = -4163
Const xlValues = &HFFFFEFBD ' -4163
Const xlNone   = &HFFFFEFD2 ' -4142
Const xlSelect = 3
Const xlCellTypeLastCell = 11 
Or you can "Include" them like this:
[reflection.assembly]::loadWithPartialname("Microsoft.Office.Interop.Excel") |
Out-Null
$xlConstants = "microsoft.office.interop.excel.Constants" -as [type]
$ws.columns.item("F").HorizontalAlignment = $xlConstants::xlCenter
$ws.columns.item("K").HorizontalAlignment = $xlConstants::xlCenter
 If you know what constants you need.
