 How did they discover Fuzzy Look-up add-in for Excel (A write-up by Paras)?

Some months ago, Mantresh approached me to see if I knew any tool that would help him deal with “messy” data. On Further questions, I learned that

–          Messy data = lots of duplicates

–          Uses SQL Server Express & do NOT have plans to upgrade to SQL Server versions that include Data Quality Services and/or Master Data Services. Remember the context here: They are a small and medium size business.

–          Do use Excel – a lot!

–          Do not have folks w/ “SQL” knowledge

With this requirements, I asked him to see if an add-in for excel called “Fuzzy Lookup” meets their need. After trying it out: here’s Mantresh’s experience of using Fuzzy Lookup add-in for Excel in their organization:


In my company we are implementing ERP software. I faced a problem of Data migration from two fox Pro based software’s to SQL (for ERP)

More Details:

Two fox Pro Software’s worked independently form each other. And as a result each of them had their Separate Databases.

Lets Call them FX1 and FX2.

Now I wanted to import Account Master Data from them to SQL, Here are the fields in our Account Master data:

Name, Address, Bank Details, Phone Number among other fields


Both systems had issues of data Duplication and Data Inconsistency

To give you an example, I faced following problems:

1) FX1 had around 3500 entries and FX2 had 2400 entries

Now in FX1 out of 3500 around 2000 were same as FX2

Also FX2 had around 2000 entries same as FX1

Now i wanted to import only unique Account Master gathered by “combining” the two systems to SQL.


FX1 has “VMS Industires” while FX2 has “V.M.S Industries”


Fuzzy Look up add-in for Excel.

Step 1) Import data from both databases to excel

Step 2) Using Fuzzy Look up to find data matching to each other based on variable conditions that we select.

Step 3) It reorganizes data as

FX1 entry1st matching FX2 Entry
2nd Matching FX2 entry

This is how we  find Duplicate entries and then clean our data-set


If not for Fuzzy Look I would have had to manually match each entry to each other which would have taken estimated 60 to 100 Man Hours but with Fuzzy Look-up, we did the job in 24 Man Hours Only.
