When it comes to managing and analyzing data in Google Sheets, one of the most common tasks is to count unique names. Whether you’re working on a project, managing a team, or tracking customer information, counting unique names is an essential step in understanding your data. However, with large datasets, it can be a time-consuming and tedious task to manually count unique names. This is where Google Sheets’ built-in functions and formulas come in handy.
In this article, we’ll explore how to count unique names in Google Sheets using various methods and formulas. We’ll also cover some advanced techniques and best practices to help you get the most out of your data.
Method 1: Using the COUNTIF Function
The COUNTIF function is a powerful tool in Google Sheets that allows you to count cells that meet a specific condition. To count unique names using the COUNTIF function, follow these steps:
- Enter the range of cells that contains the names you want to count.
- Enter the criteria for the names you want to count. For example, if you want to count unique first names, enter “A1:A100” (assuming the names are in column A).
- Use the COUNTIF function to count the cells that meet the criteria. The syntax is: `=COUNTIF(range, criteria)`
For example, if you want to count unique first names in column A, the formula would be: `=COUNTIF(A1:A100, A1:A100)`
Counting Unique Names with Multiple Criteria
What if you want to count unique names based on multiple criteria? For example, you want to count unique names that have a specific title (Mr./Ms./Mrs.) and are from a specific department? You can use the COUNTIF function with multiple criteria by separating the criteria with commas.
| Criteria 1 | Criteria 2 | Formula |
|---|---|---|
| A1:A100 | B1:B100 | =COUNTIF(A1:A100, A1:A100, B1:B100, B1:B100) |
Method 2: Using the UNIQUE Function
The UNIQUE function is a newer function in Google Sheets that allows you to extract a unique list of values from a range of cells. To count unique names using the UNIQUE function, follow these steps: (See Also: How to Refresh Google Finance in Sheets? Easily Update Data)
- Enter the range of cells that contains the names you want to count.
- Use the UNIQUE function to extract a unique list of names. The syntax is: `=UNIQUE(range)`
- Use the COUNT function to count the unique names. The syntax is: `=COUNT(UNIQUE(range))`
For example, if you want to count unique first names in column A, the formula would be: `=COUNT(UNIQUE(A1:A100))`
Counting Unique Names with Multiple Criteria using the UNIQUE Function
What if you want to count unique names based on multiple criteria using the UNIQUE function? You can use the UNIQUE function with multiple criteria by using the FILTER function.
| Criteria 1 | Criteria 2 | Formula |
|---|---|---|
| A1:A100 | B1:B100 | =COUNT(FILTER(UNIQUE(A1:A100, B1:B100), A1:A100, B1:B100)) |
Method 3: Using the Query Function
The QUERY function is a powerful tool in Google Sheets that allows you to extract data from a range of cells using a SQL-like syntax. To count unique names using the QUERY function, follow these steps:
- Enter the range of cells that contains the names you want to count.
- Use the QUERY function to extract a unique list of names. The syntax is: `=QUERY(range, “SELECT DISTINCT name”)`
- Use the COUNT function to count the unique names. The syntax is: `=COUNT(QUERY(range, “SELECT DISTINCT name”))`
For example, if you want to count unique first names in column A, the formula would be: `=COUNT(QUERY(A1:A100, “SELECT DISTINCT A”))`
Counting Unique Names with Multiple Criteria using the Query Function
What if you want to count unique names based on multiple criteria using the QUERY function? You can use the QUERY function with multiple criteria by using the WHERE clause.
| Criteria 1 | Criteria 2 | Formula |
|---|---|---|
| A1:A100 | B1:B100 | =COUNT(QUERY(A1:A100, “SELECT DISTINCT A WHERE A = A AND B = B”)) |
Best Practices and Tips

- Make sure to enter the range of cells correctly. The range should include the entire column or row of data you want to count.
- Use the correct criteria for the COUNTIF function or the UNIQUE function. Make sure to specify the correct column or range of cells for the criteria.
- Use the COUNT function to count the unique names. This will give you the correct count of unique names.
- Use the UNIQUE function or the QUERY function to extract a unique list of names. This will help you avoid duplicates and get an accurate count.

FAQs
What is the difference between the COUNTIF function and the UNIQUE function?
The COUNTIF function counts the number of cells that meet a specific condition, while the UNIQUE function extracts a unique list of values from a range of cells. The UNIQUE function is more powerful and flexible than the COUNTIF function, but it requires more setup and configuration.
How do I count unique names with multiple criteria?
You can count unique names with multiple criteria using the COUNTIF function or the UNIQUE function. For the COUNTIF function, you can use multiple criteria by separating the criteria with commas. For the UNIQUE function, you can use multiple criteria by using the FILTER function.
What is the best method for counting unique names?
The best method for counting unique names depends on the size and complexity of your data. The COUNTIF function is a simple and easy-to-use method, while the UNIQUE function is more powerful and flexible. The QUERY function is a good option if you need to count unique names with multiple criteria.
Can I use the COUNTIF function with a range of cells that contains multiple columns?
Yes, you can use the COUNTIF function with a range of cells that contains multiple columns. Simply specify the range of cells that contains the data you want to count, and the COUNTIF function will count the cells that meet the specified condition.
How do I count unique names in a column that contains blank cells?
If you want to count unique names in a column that contains blank cells, you can use the COUNTIF function with the IF function. The IF function will ignore blank cells and count only the cells that contain data.
