Question

I am trying to automatically truncate a long conversation between two people which has been pasted into word.
Input
Jim , 18th November 05:23
Hi!
Sarah , 19th November 06:03
Hello there
I want to format all text from Jim blue, and all text from Sarah red. In order to do this I think I need to follow this process:
Colour every bit of text red
Find a line starting with "Jim ," and format everything after it blue until it reaches a line which starts with "Sarah ,".

Answer 1

Hope this helps

For Each line_in_para In ActiveDocument.Paragraphs

If InStr("Jim", check_name(0)) Then
color_the_text = False
ElseIf InStr("Sarah", check_name(0)) Then
color_the_text = True
End If
