Pretty Print Excel Formulas?

Try Excel Formula Beautifier http://excelformulabeautifier.com/. It pretty prints (aka beautifies) Excel formulas.

(I help maintain this, always looking for feedback to make it better.)

This VBA code will win no awards, but it's O.K. for quickly looking at typical formulas. It just does what you'd do with parens or separators manually. Stick it in a code module and call it from the VBA immediate window command line. (EDIT: I had to look at some formulas recently, and I improved on what was here from my original answer, so I came back and changed it.)

Public Function ppf(f) As String
    Dim formulaStr As String

    If IsObject(f) Then
        Debug.Assert TypeOf f Is Range

        Dim rng As Range
        Set rng = f

        formulaStr = rng.Formula
    Else
        Debug.Assert VarType(f) = vbString

        formulaStr = f
    End If

    Dim tabs(0 To 99) As Long

    Dim tabNum As Long
    tabNum = 1

    Dim tabOffset As Long

    Dim i As Long
    Dim c As String
    For i = 1 To Len(formulaStr)
        c = Mid$(formulaStr, i, 1)

        If InStr("({", c) > 0 Then
            ppf = ppf & c

            tabNum = tabNum + 1
            tabs(tabNum) = tabs(tabNum - 1) + tabOffset + 1
            tabOffset = 0

            ppf = ppf & vbCrLf & Space(tabs(tabNum))
        ElseIf InStr(")}", c) > 0 Then
            tabNum = tabNum - 1
            tabOffset = 0

            ppf = ppf & c & vbCrLf & Space(tabs(tabNum))
        ElseIf InStr("+-*/^,;", c) > 0 Then
            tabOffset = 0

            ppf = ppf & c & vbCrLf & Space(tabs(tabNum))
        Else
            ppf = ppf & c

            tabOffset = tabOffset + 1
        End If
    Next i
End Function

If you call it like so:

?ppf([q42])

you don't have to worry about escaping your double quotes and so on. You'll get output that looks like this:

AC6+
AD6+
(
 IF(
    H6="Yes",
    1,
    IF(
       J6="Yes",
       1,
       0)
    )
 )
+
IF(
   X6="Yes",
   1,
   0)

You can also call it with a plain string.
