Those little boxes could be different characters.
Line feeds (=char(10) as a worksheet formula or vblf in code) will show up as
little squares if you haven't turned on wrap text. After you toggle the wrap
text setting, then you'll see multiple lines within the cell.
Carriage returns (=char(13) or vbcr) will show up as little squares. The wrap
text setting won't change them.
Saved from a previous post.
Chip Pearson has a very nice addin that will help determine what that
character(s) is:
http://www.cpearson.com/excel/CellView.aspx
Depending on what that character is, you may be able to use alt-#### (from the
number keypad) to enter the character into the Other box in the text to columns
wizard dialog.
In fact, you may be able to select the character (in the formula bar), and copy
it. Then use ctrl-v to paste into that text to columns Other box.
You may be able to use Edit|Replace to change the character--Some characters can
be entered by holding the alt-key and typing the hex number on the numeric
keypad. For example, alt-0010 (or ctrl-j) can be used for linefeeds. But I've
never been able to get alt-0013 to work for carriage returns.
Another alternative is to fix it via a formula:
=substitute(a1,char(##),"")
Replace ## with the ASCII value you see in Chip's addin.
Or you could use a macro (after using Chip's CellView addin):
Option Explicit
Sub cleanEmUp()
Dim myBadChars As Variant
Dim myGoodChars As Variant
Dim iCtr As Long
myBadChars = Array(Chr(##)) '<--What showed up in CellView?
myGoodChars = Array("")
If UBound(myGoodChars) <> UBound(myBadChars) Then
MsgBox "Design error!"
Exit Sub
End If
For iCtr = LBound(myBadChars) To UBound(myBadChars)
ActiveSheet.Cells.Replace What:=myBadChars(iCtr), _
Replacement:=myGoodChars(iCtr), _
LookAt:=xlPart, SearchOrder:=xlByRows, _
MatchCase:=False
Next iCtr
End Sub
