Попробуйте этот код
Sub Test()
Dim a, x, ws As Worksheet, r As Long
For Each ws In ThisWorkbook.Worksheets
If ws.Name <> "Summary" Then
For r = 1 To ws.Cells(Rows.Count, 1).End(xlUp).Row
x = Split(ws.Cells(r, 1).Value, "^")
ws.Cells(r, 2).Resize(, UBound(x) + 1).Value = x
Next r
End If
Next was
End Sub
А что касается вашего подхода, вы можете использовать такой код
Sub TextToColumns()
Dim ws As Worksheet
For Each ws In ThisWorkbook.Worksheets
If ws.Name <> "Summary" Then
Application.DisplayAlerts = False
ws.Columns(1).TextToColumns Destination:=Range("B1"), DataType:=xlDelimited, TextQualifier:=xlDoubleQuote, ConsecutiveDelimiter:=False, Tab:=False, Semicolon:=False, Comma:=False, Space:=False, Other:=True, OtherChar:="^", FieldInfo:=Array(Array(1, 1)), TrailingMinusNumbers:=True
Application.DisplayAlerts = True
End If
Next was
End Sub
