Advanced Find/Replace Excel Macro Mới Cập Nhật

Sure, I can help you with that!

Here’s an example of an advanced find/replace macro that you can use in Excel:

vbnet
Sub AdvancedFindReplace()
    
    ' Set variables
    Dim FindWhat As String
    Dim ReplaceWhat As String
    Dim i As Integer
    Dim j As Integer
    Dim k As Integer
    
    ' Prompt user for find and replace values
    FindWhat = InputBox("Enter text to find:")
    ReplaceWhat = InputBox("Enter replacement text:")
    
    ' Loop through each worksheet in workbook
    For i = 1 To Worksheets.Count
        Worksheets(i).Activate
        
        ' Loop through each cell in worksheet
        For j = 1 To Cells.SpecialCells(xlCellTypeLastCell).Row
            For k = 1 To Cells.SpecialCells(xlCellTypeLastCell).Column
                
                ' Check if cell contains find value
                If InStr(1, Cells(j, k), FindWhat) <> 0 Then
                    
                    ' Replace value if found
                    Cells(j, k) = Replace(Cells(j, k), FindWhat, ReplaceWhat)
                    
                End If
                
            Next k
        Next j
    Next i
    
    ' Inform user that macro has finished
    MsgBox "Macro has finished running."
    
End Sub

To use this macro, open the VBA editor in Excel (usually by pressing Alt+F11), create a new module, and paste in the code above. Then you can run the macro from the Macros dialog box in Excel.

This macro prompts the user for the text to find and the replacement text, then loops through each worksheet in the workbook and each cell in the worksheet, checking if the cell contains the find value. If it does, it replaces the value with the replacement text.

Note that this macro does not use any advanced search criteria such as regular expressions or wildcards. If you need more advanced search options, you may need to modify the code or use a different macro.

Yes, you can find and replace in an Excel macro using VBA (Visual Basic for Applications) code.

Here’s an example of how to do it:

1. Open the Visual Basic Editor in Excel by pressing Alt + F11.
2. In the Project Explorer, locate the workbook where you want to create the macro and double-click on it to open its modules.
3. Insert a new module by clicking Insert > Module.
4. In the module, write the following code to find and replace a specific value in a worksheet:

vbnet
Sub FindReplace()
    Dim ws As Worksheet
    Set ws = ActiveWorkbook.Sheets("Sheet1") ' Replace "Sheet1" with the name of your worksheet
    
    ws.Cells.Replace What:="old value", Replacement:="new value", LookAt:=xlPart, _
        SearchOrder:=xlByRows, MatchCase:=False, SearchFormat:=False, _
        ReplaceFormat:=False
End Sub

1. Customize the code to fit your needs. For example, you can change the name of the worksheet, the old and new values, and the search options.
2. Save the module and close the Visual Basic Editor.
3. To run the macro, go back to the worksheet and press Alt + F8 to open the Macro dialog box. Select the macro you just created and click Run.

This code will replace all instances of “old value” in the specified worksheet with “new value”. If you want to replace values in multiple worksheets, you can use a loop to iterate through each worksheet in the workbook.

Yes, there is a Replace function in VBA. The Replace function is used to replace one set of characters with another set of characters within a string. The syntax for the Replace function is as follows:

css
Replace(Expression, Find, ReplaceWith, [Start], [Count], [Compare])

where:

• Expression: Required. The string expression to be searched.
• Find: Required. The substring to be replaced.
• ReplaceWith: Required. The replacement substring.
• Start: Optional. The position within Expression where the search is to begin. If omitted, the search begins at the first character position.
• Count: Optional. The number of occurrences to be replaced. If omitted, all occurrences of Find within Expression are replaced.
• Compare: Optional. Specifies the type of comparison. If omitted, a binary comparison is performed.

Here’s an example usage of the Replace function:

vbnet
Dim myString As String
myString = "Hello, World!"
myString = Replace(myString, "World", "Universe")
' The value of myString is now "Hello, Universe!"

In the example above, the Replace function replaces the substring “World” with the substring “Universe” in the myString variable.

To find and replace multiple values at once in Excel VBA, you can use the Replace function in a loop. Here’s an example code that demonstrates how to replace multiple values in a range of cells:

vbnet
Sub FindAndReplace()
    Dim rng As Range
    Dim oldValue As Variant
    Dim newValue As Variant
    
    Set rng = Range("A1:C10") 'Set the range of cells to search and replace
    
    'Replace multiple values in a loop
    For Each oldValue In Array("apple", "orange", "banana") 'Add the values to replace in the Array function
        newValue = "fruit" 'Set the new value to replace with
        rng.Replace oldValue, newValue, xlWhole, xlByRows, False 'Perform the find and replace operation
    Next oldValue
End Sub

In this code, the Range object rng is set to the range of cells to search and replace. The For Each loop iterates through an array of values to replace, and for each value, the Replace function is called to replace the old value with the new value ("fruit" in this example) in the specified range. The xlWhole parameter specifies that only whole cell matches should be replaced, the xlByRows parameter specifies that the search should be performed row by row, and the False parameter specifies that the search should be case-sensitive. You can modify these parameters according to your specific requirements.
