Dynamic Array Formulas in Excel
Last Updated :
23 Jul, 2022
Dynamic arrays are resizable arrays that calculate automatically and return value into multiple cells based on a formula entered in a single cell. The new array (multiple cells) that we get is known as spilling and the new array has been placed in neighboring cells. It is not necessary to use Ctrl + Shift + Enter to enter an array formula. Dynamic array formulas are only available in Excel 365 and Excel 2021.
Dynamic Array Formulas
Below mentioned array formulas are the dynamic array formulas, let’s learn in detail how these formulas are applied in excel on a certain dataset.
- UNIQUE
- SORT
- SORT BY
- SEQUENCE
- RANDARRAY
- FILTER
- LOOKUP
UNIQUE Formula
Unique formulas return a list of unique values in a list. Unique means that element that appears only once in an array. Values can be text, number, etc. A unique function is not case-sensitive means ‘Apple’ and ‘apple’ are the same. Syntax,
=UNIQUE(A3:A17)
fig 1. Print only Unique Values
SORT Formula
Sort formula returns a list in increasing order or decreasing order. Values can be text, number, etc. Syntax,
=SORT(A4: A10) increasing order.
fig 2. Sort the values
SORTBY Formula
SORTBY formula sorts the contents of a range based on values from another array. Values can be text, number, etc. Syntax,
=SORTBY(A4:A10,B4:B10,-1)
Here, -1 is used for only decreasing order.

SEQUENCE Formula
The sequence formula allows you to generate a list of sequential numbers in an array. List can be 1D, 2D determined by rows and columns arguments. Syntax,
=SEQUENCE (5,6)
It will generate five rows and 6 columns, so the value will be from1 to 30.

RANDARRAY Formula
RANDARRAY formula generates an array of random numbers. Generated values can be either decimals or whole numbers. The size of the array is specified by rows and columns arguments. Syntax,
=RANDARRAY(1,2)
fig 5. Generate random value
FILTER Formula
The filter formula filters a range of data based on given criteria. It returned an array of filtered values. In this formula we print only those values which are greater than 100. Syntax,
=FILTER(A4:A12,A4:A12>100)
fig 6. Using filter formula
LOOKUP Formula
The Excel LOOKUP function returns a value from a range (one row or one column) or an array. If you want to search any number from an array then we use this function. Syntax,
=LOOKUP(value, lookup _ range, [result _range])
For Example: when we use the lookup function so =LOOKUP(10502,A4:A9,B4:B9) then we got PETER ENGLAND as a resultant.
