Sort the datasource on the Last Name then First Name columns then add
another column to your Excel datasource that you populate by using a formula
that grabs the first letter of the LastName field (=Left(cellref, 1). Then
set up a director or catalog type mailmerge main document with the
mergefields in the first row of a one row table so that it produces
A Adams, John [other fields]
A [additional names beginning with A
B Brown, Mary
B [additional names beginning with B
etc.
Then run the following macro of the document created by executing that
merge:
Dim source As Document, target As Document, scat As Range, tcat As Range
Dim data As Range, stab As Table, ttab As Table
Dim i As Long, j As Long, k As Long, n As Long
Set source = ActiveDocument
Set target = Documents.Add
Set stab = source.Tables(1)
k = stab.Columns.Count
Set ttab = target.Tables.Add(Range:=Selection.Range, numrows:=1,
numcolumns:=k - 1)
Set scat = stab.Cell(1, 1).Range
scat.End = scat.End - 1
ttab.Cell(1, 1).Range = scat
j = ttab.Rows.Count
For i = 1 To stab.Rows.Count
Set tcat = ttab.Cell(j, 1).Range
tcat.End = tcat.End - 1
Set scat = stab.Cell(i, 1).Range
scat.End = scat.End - 1
If scat <> tcat Then
ttab.Rows.Add
j = ttab.Rows.Count
ttab.Cell(j, 1).Range = scat
ttab.Rows.Add
For n = 2 To k
Set data = stab.Cell(i, n).Range
data.End = data.End - 1
ttab.Cell(ttab.Rows.Count, n - 1).Range = data
Next n
Else
ttab.Rows.Add
For n = 2 To k
Set data = stab.Cell(i, n).Range
data.End = data.End - 1
ttab.Cell(ttab.Rows.Count, n - 1).Range = data
Next n
End If
Next i
It will create a new documnet with the data arranged as you want it.
