which outputs the 2 distinct values in the data, "purple", and "gray".
How this formula works
This example uses the UNIQUE function. With default settings, UNIQUE will output a list of unique values, i.e. values that appear one or more times in the source data. However, UNIQUE has an optional third argument, called "occurs_once" that, when set to TRUE, will cause UNIQUE to return only values that appear once in the data.
In the example shown, UNIQUE's arguments are configures like this:
array - B5:B16
by_col - FALSE
occurs_once - TRUE
Because occurs_once is set to TRUE, UNIQUE outputs the 2 values in the data that appear just once: "purple", and "gray".
Notice the by_col argument is optional and defaults to FALSE, so it can be omitted:
UNIQUE won't automatically change the source range if data is added or deleted. To give UNIQUE a dynamic range that will automatically resize as needed, you can use an Excel Table, or create a dynamic named range with a formula.
Note: This function is a new "Dynamic Array Function" in Excel. It is a beta feature available only through the Office Insiders program. Dynamic Array functions are expected to be released in 2019 to Office 365 subscribers.
To extract a list of unique values from a set of data, you can use the UNIQUE function . In the example shown, the formula in D5 is: = UNIQUE ( B5:B16 ) which outputs the 7 unique values seen in D5:D11. How this formula works This example uses the...
The Excel UNIQUE function returns a list of unique values in a list or range. Values can be text, numbers, dates, times, etc.
