report format indentations

I have received a word document in format

group 1
  member 1
  member 2
  member 3
group 2
  member 1
  member 2
  memeber 3

Its proving hard to do analysis, I would like to autofilter for say all members of group 1. Is there anyway to import this data into excel so it would be like

group    members
--------------------------
1             member 1
1             member 2
1             member 3
2             member 1
2             member 2
2             member 3

I cant see how on earth to format it in this way. From what i can see the indent is 3 characters.
