The Dynamic Array functions of Excel are beneficial. These functions have the ability to work with multiple values in a simpler way. In this article, we will have a look at some of those beneficial functions. These functions can be used to filter, sort, remove duplicates, etc. Dynamic arrays are resizable arrays that calculate automatically and return values into multiple cells based on a formula in a given single cell.

Dynamic Array Functions

  1. Filter: This function filters a range of cells or tables based on an input criterion.
  2. Unique: This function is used to find unique items from a range of cells or tables.
  3. Sort: This function sorts a list by a specified column.
  4. Sortby: This function is used to sort a list by another list.
  5. Sequence: This function generates a series of numbers in a range of rows and/or columns.
  6. Randarray: This function is used to create a range of random numbers.

What does SPILL mean in Excel?
Spill refers to errors. #Spill errors are returned when a formula returns multiple results, and Excel cannot return the results to the grid.

Extra features that can be enabled through these DA Functions are:-

  1. We can use the # operator to refer to a range of cells spilled by DA functions.
  2. We don’t need to press CTRL+SHIFT+ENTER as most array functions will spill into a range of cells.
  3. It will automatically spill if any formula or name refers to more than one value.

Syntax of some DA functions

  1. Filter 
    =FILTER(your data, conditions, if empty value)
  2. Unique 
    =UNIQUE(list, data is across the columns?, do you want values occurring just once?)
  3. Sort 
    =SORT(list, column number, ascending or descending order, do you want to sort across the columns instead?)
  4. Sortby 
    =SORTBY(list, criteria list 1, sort order 1, criteria list 2, sort order 2…)
  5. Sequence 
    =SEQUENCE(row count, column count, starting number, step by)
  6. Randarray 
    =RANDARRAY(row count, column count, starting number, ending number, do you want just random integers?)

How Dynamic Arrays interact with other Excel Functions

  1. Spill Ranges in other formulas: We can refer to spill ranges using the # operator.
  2. Named Ranges and DA functions: We can create named ranges that refer to spill range, and we can also use named ranges inside DA functions.
  3. Using DA functions with named ranges: We can solve some challenging problems using DA functions combined with the array processing power of INDEX.
  4. Conditional Formatting Dynamic Arrays: Conditional formatting does not recognize dynamic spill ranges.
  5. Dynamic Arrays in Data Validation: We can use the # operator to refer to dynamic array range with data validation rules.
  6. Charting & Dynamic Arrays: Excel charts don’t recognize spill range operators.

  1. Is XLOOKUP() a dynamic array function?
    Yes, XLOOKUP() is a dynamic array function.
  2. What Excel versions support dynamic arrays?
    Excel 365 and Excel 2021.
  3. What is Excel Dynamic Array?
    Dynamic Array Functions allows formulae to return multiple results to a range of cells based on a single formula entered in a cell.
  4. How do we select dynamic range in Excel?
    A way to create a dynamic named range with a formula is to use the OFFSET function along with the COUNTA function.
  5. Difference between XLOOKUP and VLOOKUP functions.
    The range for VLOOKUP includes the entire column, but for XLOOKUP, it splits the referenced fields into a range to search and find the value.
