To better understand how this addon works you can go through the tutorial and documentation given about it on the website or click the given links. You can also read about the popular fuzzy matching algorithms being used in this addon.

How to Fuzzy Match in Google Sheets?

Let’s see how to fuzzy match in Google sheets. For example, you have a sheet with data as shown in the above screenshot. You have name in the first column, salary in the second column, and the third column contains just names.

Your objective is to match the names of column 3 from column 1 and pull out the salaries of each person and update the correct salaries for names in column 3. So now you need to write the formula for it, which should be:

=FLOOKUP(lookupValue, tableArray, lookupCol, indexNum, threshold, rank)

So for the above Google Sheet this will translate into:


This function will match the names in column 3 with that in column 1 and then match the salaries given. So even if the list of names in column 3 is random and has some typos, the salaries would be matched with some errors as can be seen in the screenshot below.

So for the names it was not able to match the salary, we will run this query again with a bit of change in the function. Everything remains same but at the end we will add 0.5 percent similarity level. This 0.5 increases the similarity precision and gives better results. So now your query looks like the one below.


Now the results which had errors earlier would be fixed and the new results are displayed in the screenshot below.

Now the data is matched perfectly. In case you get error again you can change the percent similarity level further and run the query again.

How to Remove Duplicates with ULIST?

When you need to find unique data from the list and remove duplicate copies of the same data, then use the ULIST function in Google sheets. Using this function you can remove duplicate data from a sheet and get unique values. So we will try this on the same table as we used in the fuzzy match example.

In this list there are several names which have been repeated. Now we want only data with unique values with out the duplicates. So we run the ULIST query like seen below:

=ULIST(colArray, indexNum, threshold)

For the table we are using this will translate to:


This query will run and pull out unique data from the given table, as can be seen in the screenshot below. The heading “unique by name” column contains unique data picked out from the “full name” table in column A.

Again if there are some errors, then you can change the similarity percentage level in the query and run again to get error free results.

How to get Sound match results in Google sheets?

Apart from fuzzy match and remove duplicate data this addon let’s carry out another function called soundmatch syntax, where similar sounding data is pulled even if there are mistakes or typos.

Like in the table we are using we can pick out a name and ask the soundmatch function to pull out names which sound similar to the name we picked. This function will pull out all the name which sound similar to the one we picked even if there are typos or mistakes in the other names.

The syntax for soundmatch is given below:

=SOUNDMATCH(lookupValue, tableArray, lookupCol, indexNum, rank)

So for the table we are using, this will translate into the below given syntax:


So we picked the name in the “A11” cell and we want the function to search any other name which sounds similar to this one. If yes, then all the names which sound similar will be shown in the result.

As you can see in the above screenshot, we picked out the name in “A11” which is highlighted in red. The syntax searched for a name sounding the same and pulled out the result in the soundmatch column on the right. Even with typos the soundmatch syntax was able to find a similar name.


Flookup addon offers some very good functions with its free version like fuzzy match, remove duplicates, soundmatch, etc. The functions provide near accurate results and are easy to understand. This addon is optimized to run the fuzzy matching algorithm in the shortest time possible. Thus, making this addon fast and reliable. If you find the functions provided great and need more functions for your Google sheets, then you can upgrade to the paid version of the addon which contains more functions in it. Try this addon for Google Sheets.
