獲取 Excel 中使用的最后一個單元格的值

Question

$objExcel = New-Object -ComObject Excel.Application
$objExcel.Visible = $false
$WorkBook = $objExcel.Workbooks.Open($filepath)
$WorkBook.Sheets | Select-Object -Property Name
$WorkSheet = $WorkBook.Sheets.Item($sheetname)
$worksheetrange = $WorkSheet.UsedRange
$last = $worksheetrange.Rows.Count

我已經使用了 3 行並得到了一個正確的答案 3，我想獲得第 3 行中的值，並且隨着我們繼續添加該行，如何追加？

Answer 1

如果你想堅持使用powershell。 試試這個..

$objExcel = New-Object -ComObject Excel.Application
$objExcel.Visible = $False
$WorkBook = $objExcel.Workbooks.Open($filepath)
$WorkSheet = $objExcel.WorkSheets.item($sheetname)
$WorkSheet.activate()

[int]$lastRowvalue = ($WorkSheet.UsedRange.rows.count + 1) - 1
$lastrow = $WorkSheet.Cells.Item($lastRowvalue, 1).Value2
write-host $lastrow

$objExcel.Quit()
[System.Runtime.Interopservices.Marshal]::ReleaseComObject($objExcel) | out-null

我假設您已經指定了$filepath和$sheetname 。 每次運行后不要忘記關閉excel。

這樣做，只需為您的實際工作表更改 Sheet1：

LastRow = Sheet1.Cells(Sheet1.Rows.Count, "A").End(xlUp).Row 
'This will find the last used row on column A of Sheet1

value = Sheet1.cells(LastRow,1).value 
'Place the value of that cell into a variable

Msgbox value 
'Display the variable to the user in a msgbox

Shanayl 提供的方法工作正常，但請記住，它使用不計算空白的計數方法。 下面一個是：

$filepath = "F:\Drives.xlsx"
$xl=New-Object -ComObject "Excel.Application"  
$wb=$xl.Workbooks.open($filepath)
$ws=$wb.ActiveSheet 
$cells=$ws.Cells

$Lastrowno =$Ws.UsedRange.SpecialCells(11).row
