Introduction
The UNIQUE function in Excel is an incredibly useful tool when you
want to find distinct or non-repeating values from a range of data. Whether
you're dealing with names, prices, categories, or any other data, the UNIQUE
function allows you to quickly extract the unique elements. However, when
combined with other powerful functions like FILTER, SORT, COUNTIF, SUMIF, and
more, it becomes even more versatile and efficient. In this tutorial, we’ll
explore eight expert-level tricks and tips that demonstrate how the
UNIQUE function works alongside other Excel functions. Let’s dive in!
1. UNIQUE + FILTER: Extracting Unique Values Based on a Condition
One of the most powerful combinations with the UNIQUE function is
using it alongside FILTER. This combination allows you to get unique values
from a dataset based on specific conditions. In this case, let's say you want
to extract the unique product names that belong to the "Tech"
category.
Here’s the formula:
=UNIQUE(FILTER(B2:B11, C2:C11="Tech"))
In this example, column B contains the product names, and column C contains their categories (such as "Tech", "Office", etc.). The FILTER function first filters the product names (column B) based on whether their corresponding category in column C equals "Tech". Once you’ve filtered out only the "Tech" products, the UNIQUE function extracts the distinct names. This means if "Laptop" appears multiple times under "Tech", it will only appear once in the result.
This combination is incredibly useful when you have a large dataset
and need to focus on a specific category or condition while eliminating
duplicates. For example, if you’re analyzing sales data and only want to look
at unique products sold in the "Tech" department, this formula gives
you an efficient way to filter and list those items.
2. UNIQUE + SORT: Organizing Unique
Values in Ascending Order
Sorting is another essential function in Excel, and when paired
with UNIQUE, it can help organize your data neatly. For instance, if you have a
list of prices, and you want to get the unique prices in ascending order, you
can use the following formula:
=SORT(UNIQUE(D2:D11))
In this example, column D contains the product prices. First, the UNIQUE function extracts all distinct prices from the list, removing any duplicates. Then, the SORT function arranges these unique prices in ascending order. This is especially helpful when you want to see the different price points of your products without any repetition, and in an organized manner from lowest to highest.
For example, if your dataset contains multiple products with
repeated prices, this formula will help you eliminate the duplicates and
present the prices in a clean, ordered list. It’s an excellent tool for making
financial or inventory data more readable and organized.
3. UNIQUE + COUNTIF: Counting the
Occurrences of Each Unique Value
The UNIQUE function can also be used in combination with COUNTIF to
count how many times each unique item appears in your dataset. This is
particularly useful when analyzing frequency data, such as how often each
product was sold.
Here’s how you can count the occurrences of each unique product
name:
=COUNTIF(B2:B11, UNIQUE(B2:B11))
In this case, the UNIQUE function first extracts all distinct product names from column B. Then, the COUNTIF function counts how many times each unique product appears in the dataset. For example, if "Laptop" appears three times and "Tablet" appears twice, the result will show these counts for each unique product.
This is an excellent way to quickly determine how often different
items appear in a dataset, making it ideal for sales reports, inventory
tracking, or customer surveys where you need to see the frequency of specific
items or responses.
4. UNIQUE + SUMIF: Summing Values
for Each Unique Item
Combining UNIQUE with SUMIF allows you to sum values, like sales or
revenue, for each unique item in your dataset. Let’s say you want to calculate
the total sales for each unique product in your list:
=SUMIF(B2:B11, UNIQUE(B2:B11), E2:E11)
In this example, column B contains product names, and column E contains the corresponding sales figures. The UNIQUE function extracts the distinct product names, and then the SUMIF function sums the sales for each unique product. For instance, if "Laptop" appears multiple times with different sales numbers, the formula will sum all the sales related to "Laptop" and display the total.
This is an efficient way to consolidate sales data and see the
total performance of each product without manually summing up repeated entries.
It’s especially useful for sales reports, budget planning, or any other
scenario where you need to sum values for distinct items.
5. UNIQUE + AVERAGEIF: Calculating
the Average for Unique Items
Similar to SUMIF, AVERAGEIF can be used with UNIQUE to calculate
the average price or sales for each unique product in your dataset. This is
particularly useful for finding out the average performance of each product.
Here’s the formula:
=AVERAGEIF(B2:B11, UNIQUE(B2:B11), D2:D11)
In this case, column B contains product names, and column D contains their prices. The UNIQUE function extracts the distinct product names, and the AVERAGEIF function calculates the average price for each unique product. For instance, if "Tablet" appears several times with different prices, this formula will calculate the average price of all "Tablet" entries.
This is an excellent way to analyze pricing trends or customer
purchases, allowing you to quickly calculate the average cost of distinct items
in your dataset.
6. UNIQUE + VLOOKUP: Finding
Information for Unique Items
You can also use the UNIQUE function with VLOOKUP to find
information related to the first unique item in your dataset. For example, if
you want to find the price of the first unique product, you can use the
following formula:
=VLOOKUP(UNIQUE(B2:B11), B2:D11, 3, FALSE)
In this example, column B contains product names, column D contains prices, and the VLOOKUP function returns the price of the first unique product from the list. The UNIQUE function extracts the first distinct product name, and VLOOKUP searches for its corresponding price in the dataset.
This is a great way to quickly find specific information related to
unique items in a large dataset, such as the price, sales, or other attributes
related to the first distinct item.
7. UNIQUE + IF: Listing Unique Items
That Meet a Specific Condition
By combining the UNIQUE and IF functions, you can create more
advanced formulas that only list unique items that meet certain criteria. For
example, you may want to list unique products that are priced over 500:
=UNIQUE(IF(D2:D11>500, B2:B11, ""))
In this case, the IF function checks whether the price in column D is greater than 500. If the condition is true, the product name from column B is returned; otherwise, an empty string is returned. The UNIQUE function then removes any duplicates from the list of products priced above $500.
This formula is extremely useful for filtering your data based on
specific criteria while also ensuring that the result contains no duplicates.
Whether you’re analyzing product prices, customer orders, or any other dataset,
this combination allows you to create a refined list of unique items that meet
your specific needs.
8. UNIQUE + XLOOKUP: Finding
Information for the First Unique Item
Lastly, combining UNIQUE with XLOOKUP allows you to find detailed
information about the first unique item in your dataset. For example, if you
want to find the category of the first unique product, you can use the
following formula:
=XLOOKUP(INDEX(UNIQUE(B2:B11), 1), B2:B11, C2:C11)
In this example, the UNIQUE function extracts the list of distinct product names, and INDEX selects the first item from that list. XLOOKUP then searches for that product in column B and returns its corresponding category from column C.
This formula is incredibly powerful for retrieving detailed
information about unique items. Whether you’re looking for categories, prices,
sales, or other attributes, this combination ensures that you’re working with
unique data points, making your analysis more accurate and efficient.
Conclusion
The UNIQUE function is an invaluable tool for cleaning up your data
and extracting only the distinct values you need. However, when combined with
other functions like FILTER, SORT, COUNTIF, SUMIF, and XLOOKUP, it becomes a
powerhouse for advanced data analysis. Whether you’re working with product
lists, sales data, or any other type of information, these combinations of the
UNIQUE function will help you become an expert at managing and analyzing large
datasets in Excel.
