特定の列と特定のシートのデータを含む最後の行を見つけるにはどうすればよいですか?
14 に答える
どうですか:
Function GetLastRow(strSheet, strColumn) As Long
Dim MyRange As Range
Set MyRange = Worksheets(strSheet).Range(strColumn & "1")
GetLastRow = Cells(Rows.Count, MyRange.Column).End(xlUp).Row
End Function
コメントに関しては、最後の行の 1 つのセルだけにデータがある場合でも、これは最後のセルの行番号を返します。
Cells.Find("*", SearchOrder:=xlByRows, SearchDirection:=xlPrevious).Row
を使用する必要があります.End(xlup)
が、65536 を使用する代わりに、次を使用することをお勧めします。
sheetvar.Rows.Count
そうすれば、65536行を超えると思われるExcel 2007で機能します
シンプルかつ迅速:
Dim lastRow as long
Range("A1").select
lastRow = Cells.Find("*",SearchOrder:=xlByRows,SearchDirection:=xlPrevious).Row
使用例:
cells(lastRow,1)="Ultima Linha, Last Row. Youpi!!!!"
'or
Range("A" & lastRow).Value = "FIM, THE END"
function LastRowIndex(byval w as worksheet, byval col as variant) as long
dim r as range
set r = application.intersect(w.usedrange, w.columns(col))
if not r is nothing then
set r = r.cells(r.cells.count)
if isempty(r.value) then
LastRowIndex = r.end(xlup).row
else
LastRowIndex = r.row
end if
end if
end function
使用法:
? LastRowIndex(ActiveSheet, 5)
? LastRowIndex(ActiveSheet, "AI")
Public Function LastData(rCol As Range) As Range
Set LastData = rCol.Find("*", rCol.Cells(1), , , , xlPrevious)
End Function
使用法:?lastdata(activecell.EntireColumn).Address
.Find
組み込みの動作 (や など)に依存するすべてのソリューションに.End
は、十分に文書化されていない制限があります (詳細については、他の回答を参照してください)。
私は何かが必要でした:
- 特定の列の最後の空でないセル (空の文字列であっても、数式または値を持つセル) を検索します
- 明確に定義された動作を持つプリミティブに依存
- オートフィルターとユーザーによる変更で確実に動作
- 10,000 行で可能な限り高速に実行します (
Worksheet_Change
ハンドラーで実行しても遅く感じません) 。 - ...偶発的なデータや書式設定がシートの最後に配置されてもパフォーマンスが低下することはありません (最大 100 万行)。
以下の解決策:
UsedRange
行番号の上限を見つけるために使用します (使用される範囲の終わりに近い一般的なケースで、真の「最後の行」の検索を高速化するため)。- 逆方向に移動して、指定された列にデータがある行を見つけます。
- ...VBA配列を使用して、各行に個別にアクセスすることを回避します(
UsedRange
スキップする必要がある行が多数ある場合)
(テストはありません、ごめんなさい)
' Returns the 1-based row number of the last row having a non-empty value in the given column (0 if the whole column is empty)

' Force Excel to recalculate the "last cell" (the one you land on after CTRL+END) / "used range"

' we process in chunks of increasing size, starting with 1 cell and doubling the size on each iteration, until MAX_CHUNK_SIZE is reached.
' In pathological cases where Excel thinks all the ~1M rows are in the used range, this will take around 100ms.

最後の行、最後の列、または最後のセルを見つけるための解決策は次のとおりです。見つかった列のA1R1C1参照スタイルのジレンマに対処します。クレジットを差し上げたいのですが、どこから入手したのかわからないので、「ありがとう!」元のコードをどこかに投稿したのは誰にでも。

UsedRange
最後に使用された行を見つけるために使用する、もう 1 つの信頼できる方法を追加したいと思います。
lastRow = Sheet1.UsedRange.Row + Sheet1.UsedRange.Rows.Count - 1
同様に、最後に使用された列を見つけるには、これを見ることができます
即時ウィンドウの結果:
?Sheet1.UsedRange.Row+Sheet1.UsedRange.Rows.Count-1

Function LastRow(rng As Range) As Long
Dim iRowN As Long
Dim iRowI As Long
Dim iColN As Integer
Dim iColI As Integer
iRowN = 0
iColN = rng.Columns.count
For iColI = 1 To iColN
iRowI = rng.Columns(iColI).Offset(65536 - rng.Row, 0).End(xlUp).Row
If iRowI > iRowN Then iRowN = iRowI
Next
