Spelling mistakes are a thing of day to day carporate life. Most of the data in spreadsheets is entered by people and hence prone to having spelling mistakes or alternate spellings. For eg. a person named John could have been spelled as Jon. And when John calls you back to confirm his reservation and you use the search / vlookup to find his information the result would empty.
Here is one technique that I use often when the data has spelling mistakes or I need to do fuzzy search to fetch items that sound or spelled similar. Take the 2 texts you want to compare and,
- Remove all the vowels – AEIOU
- Replace PH with F, Z & J with G, CK with K, W with V, LL with L, SS with S
- Remove any Hs
- Finally compare both texts
To simplify the above 4 steps I have written a small VBA UDF (User Defined Function) that takes a text parameter and performs the above 4 steps.
Function SimpleText(thisTxt As String) As String
' this function generates a simple text from input text that
' can be used for fuzzy search
thisTxt = LCase(thisTxt)
thisTxt = Replace(thisTxt, "a", "")
thisTxt = Replace(thisTxt, "e", "")
thisTxt = Replace(thisTxt, "i", "")
thisTxt = Replace(thisTxt, "o", "")
thisTxt = Replace(thisTxt, "u", "")
thisTxt = Replace(thisTxt, "ph", "f")
thisTxt = Replace(thisTxt, "z", "g")
thisTxt = Replace(thisTxt, "ck", "k")
thisTxt = Replace(thisTxt, "w", "v")
thisTxt = Replace(thisTxt, "j", "g")
thisTxt = Replace(thisTxt, "ll", "l")
thisTxt = Replace(thisTxt, "ss", "s")
thisTxt = Replace(thisTxt, "h", "")
SimpleText = thisTxt
End Function
The above code can be used to perform fuzzy text searches or searches on unclean data. Of course, the above substitution rules are what I find good enough. Feel free to define additional rules as per your needs so that your fuzzy searches work even better.
If you are looking for generating SOUNDEX codes for excel strings you can use this excel soundex UDF. Soundex codes are phonetic codes generated for words based on how they sound, thus 2 words sounding similar (for eg. excess, access) would have same soundex code. You can use these codes to perform fuzzy searches.

Hi,
Just one small question. Where the hell have been I in the past for not discovering this website sooner?
I've lost a job interview recently where even though I had the subject knowledge, I was not upto their mark in Excel.
Thank you for all the free tips, guidance and for creating this forum environment.
[PS: I've just been through the site for the 1st time, and have signed up for the newsletter. You can expect pretty stupid questions from me soon]
Hy Chandoo, you always inspire me with to explore something new in excel. This data structure table is only for excel 2007 or compatible to 2010. I recently installed latest excel version 2013 in my System and experience problems regarding operating according to previous one. I'm waiting your article relates to that excel version.
Thanks

Nice to see the features considered by Excel users to be most useful. It might be a good idea to also analyze StackOverflow Excel questions to see what keywords appear most often.
