$Excel = New-Object -comobject Excel.Application 
$Excel.visible = $True

$ExcelSheet = $Excel.Workbooks.Add() 
$ExcelCell = $ExcelSheet.Worksheets.Item(1)

$ExcelCell.Cells.Item(1,1) = "Machine Name" 
$ExcelCell.Cells.Item(1,2) = "Online" 
$ExcelCell.Cells.Item(1,3) = "Drive" 
$ExcelCell.Cells.Item(1,4) = "Total size (GB)"

In PowerShell, all if-statements need braces to enclose their bodies. Below is a demonstration:

PS > if ($true) write 'true'
At line:1 char:10
+ if ($true) write 'true'
+          ~
Missing statement block after if ( condition ).
    + CategoryInfo          : ParserError: (:) [], ParentContainsErrorRecordException
    + FullyQualifiedErrorId : MissingStatementBlock

PS > if ($true) { write 'true' }
true
PS >

Therefore, the if-statement section of your script should look like this:

...
    if (Test-Connection -ComputerName $strComputer -Count 1 -Quiet)
    {
        $ExcelCell.Cells.Item($introw, 2) = "Online"

        $ExcelCell.Cells.Item($intRow, 1) = $strComputer.ToUpper() 
        $ExcelCell.Cells.Item($intRow, 3) = $objDisk.DeviceID 
        $ExcelCell.Cells.Item($intRow, 4) = "{0:N0}" -f ($objDisk.Size/1GB) 
        $ExcelCell.Cells.Item($intRow, 5) = "{0:N0}" -f ($objDisk.FreeSpace/1GB) 
        $ExcelCell.Cells.Item($intRow, 6) = "{0:P0}" -f ([double]$objDisk.FreeSpace/[double]$objDisk.Size) 
        $ExcelCell.cells.item($introw, 7) = "{0:N0}" -f ([double]$objDisk.Size/1GB - [double]$objDisk.Freespace/1GB)
    }

    else
    {
        $ExcelCell.Cells.Item($intRow, 1) = $strComputer.ToUpper() 
        $ExcelCell.Cells.Item($intRow, 2) = "Offline"
        $ExcelCell.Cells.Item($intRow, 3) = "x"
        $ExcelCell.Cells.Item($intRow, 4) = "x"
        $ExcelCell.Cells.Item($intRow, 5) = "x"
        $ExcelCell.Cells.Item($intRow, 6) = "x"
        $ExcelCell.cells.item($introw, 7) = "x"
    }
...

You use only one if statement. The syntax for if is as follows:

***IF (condition returns true) { action }***

Basically the condition is stated in round brackets, while the execution block is in curly brackets.

A simple example:

if (1 -eq 1) { Write-host "1 is equal to 1" }

Of course in the example above the condition is always true. You can use any condition you want as long as it returns boolean value (true or false).

Inside your script, in the

if (Test-Connection -ComputerName $strComputer -Count 1 -Quiet) 

there is missing curly bracket. You should open bracket after ' ) ' and close before 'else'. Afterwards, remember to put curly brackets in 'else' statement accordingly.

EDIT:

iCodez has posted already the fixed script. :-)
