如何使用 Excel vba 查找特定文本單詞

Question

我需要從 Excel 文件中查找特定單詞。 我想逐行搜索，如果找到單詞，向下跳過 2 行並復制接下來的 20 行並循環到下一個單詞。

Sub Example4()

Dim FilePath As Workbook    
Dim wsheet As Worksheet
Dim i, lcount, lcount2 As Integer
 Dim cell, rgFound As Range
Dim Found As Range, LastRow As Long


 Set FilePath = Workbooks.Open("D:\SLC.txt")
  Dim rowVal As Integer
    rowVal = 1

    For lcount = 1 To FilePath.Sheets("SLC").Range("A1048576").End(xlUp).Row

    Set rgFound = Range("A1:A1048576").Find("TXN. NO     TXN SEQ", ThisWorkbook.Sheets(), Cells(rowVal, 1))


            FilePath.Cells(wsheet.Range(rowVal).End(xlDown).Row + 3).xlCopy

            wbook2.Worksheets(1).Range("A1").PasteSpecial xlPasteValuesAndNumberFormats
            wbook2.SaveAs ("D:\SLC_Copied.xlsx")
            wbook2.Close

   rowVal = rgFound1.Row

   Debug.Print lcount
   Next lcount


End Sub

正如 Siddharth Rout 建議的那樣，使用 Find 和 FindNext。 嘗試選擇適合其類型的變量名稱，調用工作簿對象 FilePath 會讓其他試圖理解您的腳本的人感到困惑。

Option Explicit
Sub Example4()

    Const TEXT = "TXN. NO     TXN SEQ"
    Const TEXT_FILENAME = "D:\SLC.txt"
    Const OUT_FILENAME = "D:\SLC_Copied.xlsx"

    Dim wbText As Workbook, wbOut As Workbook, rngOut As Range
    Dim wsText As Worksheet, wsOut As Worksheet, count As Integer
    Dim rngSearch As Range, rngFound As Range, rowFirstFind As Long

    ' open text file no link update, read only
    Set wbText = Workbooks.Open(TEXT_FILENAME, False, True)
    Set wsText = wbText.Sheets(1)

    ' search
    Set rngSearch = wsText.Columns("A:A")
    Set rngFound = rngSearch.Find(what:=TEXT, LookIn:=xlValues, LookAt:=xlPart)

    If rngFound Is Nothing Then
        wbText.Close
        MsgBox "No lines match [" & TEXT & "]", vbCritical, "Exiting Sub"
        Exit Sub
    Else

        ' create new workbook for results
        Set wbOut = Workbooks.Add
        Set wsOut = wbOut.Sheets(1)
        Set rngOut = wsOut.Range("A1")
        rowFirstFind = rngFound.Row

        Do
            'Debug.Print rngFound.Row
            rngFound.Offset(3, 0).Resize(20, 1).Copy rngOut
            Set rngOut = rngOut.Offset(20, 0)
            Set rngFound = rngSearch.FindNext(rngFound)
            count = count + 1
        Loop Until rngFound.Row = rowFirstFind

    End If
    wbText.Close False

    wbOut.SaveAs OUT_FILENAME
    MsgBox count & " blocks copied to " & wbOut.Name, vbInformation, "Finished"
    wbOut.Close

End Sub
