If you are using an earlier version (Excel 2003 or earlier), this tip may not work for you.

Viv has a worksheet that contains lots of product descriptions. She needs a way to replace all the spaces between words with dashes. She knows she could use Find and Replace, but would prefer to use a formula to do the replacements.
Perhaps the easiest way to accomplish this task, using a formula, is to rely on the SUBSTITUTE function. At its most simple, SUBSTITUTE is used to replace one character in a text string with a different character. Thus, assuming your original product description is in cell A1, you could use the following:
=SUBSTITUTE(A1," ","-")
This formula locates every space in the text and replaces them with dashes. If you have additional product descriptions in column A and you placed this formula in cell B1, just copy the formula down as many cells as necessary.
If you are concerned that there may be leading or trailing spaces in your data, then you can expand the formula using the TRIM function:
=SUBSTITUTE(TRIM(A1)," ","-")
Either of the formulas presented so far does great at replacing regular spaces within text. Understand, however, that if you are importing your original text from a program other than Excel, the text may contain characters that look like regular spaces, but aren't really. In that case, the above approaches won't work and you'll need to do some detective work to figure out exactly what the faux spaces really are so you can replace them.

BTW, final formula for this use case was:
=LOWER(SUBSTITUTE(TRIM(B2)," ","_"))
Replaced all spaces with underscore, and transformed all CHARACTERS to lowercase.
Now have well formed column headers for data munging!

Spot on Alex!
I use the CellView addin from Chip Pearson (www.cpearson.com/excel/cellview.htm) to see the ascii code.
I have several macros either Trimming data or replacing spaces all of which I ultimately changed to incoropate CHR(160) as a space to avoid the hassle of things not working properly when CHR(160) is encountered.
I think there is a good case for the TRIM function automatically assuming CHR(160) is a space and processing it accordingly.

If you find trim isn't removing the leading & trailing spaces and / or substitute isn't handling the spaces, try isolating the character usIng MID () and finding its ASCII code using CODE() ie
=CODE(MID (A1,3,1))
- where one of the offending characters is in the 3rd position.
With a SAP application output this is likely to give you a result of 160 which the ASCII code for a non-breaking space.
You would then need to modify your substitute formula to be
=SUBSTITUTE (A1,CHAR (160),"-")
There are quite a few sources for ASCII tables but this one gives English description for the code
