Step 1: create a new Word and open it, click toolbar view - macro (inverted triangle at the bottom) - view macro

Step 2: fill in a file name and click Create

Step 3: copy the following code, replace the newly created macro code (don't delete the previous macro by mistake), pay attention to the code format, and save

Sub CommandButton1_Click()
Application.ScreenUpdating = False  'Turn off screen flash
Dim myFile$, myPath$, i%, myDoc As Object, myAPP As Object, txt$, Re_txt$
Set myAPP = New Word.Application
With Application.FileDialog(msoFileDialogFolderPicker) 'Allow users to select a folder
    .Title = "Select destination folder"
    If .Show = -1 Then
        myPath = .SelectedItems(1) 'Read the selected file path
    Else
        Exit Sub
    End If
End With
myPath = myPath & ""
myFile = Dir(myPath & "\*.docx")
txt = InputBox("Text to replace:")
Re_txt = InputBox("Replace it with:")
myAPP.Visible = True 'Show open documents or not
Do While myFile <> "" 'File is not empty
Set myDoc = myAPP.Documents.Open(myPath & "\" & myFile)
If myDoc.ProtectionType = wdNoProtection Then 'Protected or not
    With myDoc.Content.Find
        .Text = txt
        .Replacement.Text = Re_txt
        .Forward = True
        .Wrap = 2
        .Format = False
        .MatchCase = False
        .MatchWholeWord = False
        .MatchByte = True
        .MatchWildcards = False
        .MatchSoundsLike = False
        .MatchAllWordForms = False
        .Execute Replace:=2
    End With
End If
myDoc.Save
myDoc.Close
myFile = Dir
Loop
myAPP.Quit 'Turn off the temporary process
Application.ScreenUpdating = True
MsgBox ("All replaced!")
End Sub

Step 4: go back to the Word document, click View - macro, and run the macro

Step 5: pop up window, select the folder to replace the document (the file name will not be displayed under the folder)

Step 6: text to replace

Step 7: replace with

Step 8: it needs to wait for a while, and the display shows that the replacement is complete
