I have an ascii file that has data organized in blocks.
Each block's header line has a "~" in column 1.
eg.
~Well Information Block

How can I import the data in the "Curve information block" and the "~ASCII DEPTH" or sometimes called "~A DEPTH" blocks only?

I 've included some sample data.

does this give you the start you need?
it writes the lines of the blocks to columns 1 and 2 of the activesheet

once this has run you can parse those ranges with texttocolumns method



Sub ReadFromAscii()
Dim sLine$, sBlock$
Dim a&, c&

Open "c:\myascii.txt" For Input As #1

Do While Not EOF(1)
Line Input #1, sLine

If Left(sLine, 1) = "~" Then
If Left(sLine, 2) = "~C" Then
sBlock = "C"
ElseIf Left(sLine, 2) = "~A" Then
sBlock = "A"
Else
sBlock = ""
End If
Else
Select Case sBlock
Case "C"
c = c + 1
ActiveSheet.Cells(c, 1) = sLine
Case "A"
a = a + 1
ActiveSheet.Cells(a, 2) = sLine
End Select
End If
Loop
Close #1

End Sub
