You can extract them individually, which begs the question - what do you want to do with these strings having extracted them?
'Contains' upper case characters or 'comprises' upper case characters?
The following assumes only upper case characters & space (no punctuation)
Code:
Sub Macro1()
Dim oRng As Range
Dim oPara As Paragraph
Dim sText As String
For Each oPara In ActiveDocument.Paragraphs
Set oRng = oPara.Range
With oRng.Find
Do While .Execute(FindText:="^t[A-Z ]{1,}^t", MatchWildcards:=True)
If oRng.InRange(oPara.Range) Then
sText = Replace(oRng.Text, Chr(9), "")
'do something with stext e.g.
MsgBox sText
End If
oRng.Collapse 0
Loop
End With
Next oPara
lbl_Exit:
Set oRng = Nothing
Set oPara = Nothing
Exit Sub
End Sub
