Sorts array values in the specified column, array literal, or function that returns an array in ascending or descending order.
  • This function calculates based on the outer layer of an array. If your array is nested, the sorting of inner elements is not factored.

Wrangle vs. SQL: This function is part of Wrangle, a proprietary data transformation language. Wrangle is not SQL. For more information, see Wrangle Language.

Basic Usage

Array literal reference example:


Output: Returns the following array: [D,C,B,A]

Column reference example:


Output: Returns the arrays listed in the myArrays column sorted in ascending order.

Syntax and Arguments


ArgumentRequired?Data TypeDescription
array_refYstringName of Array column, Array literal, or function returning an Array to apply to the function
order_enumYstring (enumerated value)

Order is defined as either:

  • ascending (default)
  • descending

For more information on syntax standards, see Language Documentation Syntax Notes.


Name of the array column, array literal, or function returning an array whose array values you wish to sort.

  • Multiple columns and wildcards are not supported.

Usage Notes:

Required?Data TypeExample Value
YesString (column reference or function) or array literalmyArray1


String literal indicating the order by which the referenced arrays should be sorted:

  • ascending - (default) lowest values for the valid data type are listed first. 
  • descending - Null/empty values are sorted first, followed by mismatched values. Then, the array values that are valid for the specified data type are listed in descending order.  
  • For more information on the rules of sorting, see Sort Order.

Usage Notes:

Data Type
Example Value
NoString (enumerated value)descending


Tip: For additional examples, see Common Tasks.

Example - Student progress across tests

This example covers the following functions:


Here are some student test scores. Individual scores are stored in the Scores column. You want to:

  1. Flag the students who have not taken four tests.
  2. Compute the range in scores for each student.
AllenAmanda[79, 83,87,81]
BellBobby[85, 92, 94, 98]


First, you want to flag the students who did not take all four tests:

Transformation Name New formula
Parameter: Formula type Single row formula
Parameter: Formula IF(ARRAYLEN(Scores) < 4,"incomplete","")
Parameter: New column name 'Error'

This test flags Cameron Charles only.

The following transform sorts the array values in highest to lowest score:

Transformation Name Edit column with formula
Parameter: Columns Scores
Parameter: Formula ARRAYSORT(Scores, 'descending')

The following transforms extracts the first (highest) and last (lowest) value in each student's test scores, provided that they took four tests:

Transformation Name New formula
Parameter: Formula type Single row formula
Parameter: Formula ARRAYELEMENTAT(Scores,0)
Parameter: New column name 'highestScore'

Transformation Name New formula
Parameter: Formula type Single row formula
Parameter: Formula ARRAYELEMENTAT(Scores,3)
Parameter: New column name 'lowestScore'

Tip: You could also generate the Error column when the Scores4 column contains a null value. If no value exists in the array for the ARRAYELEMENTAT function, a null value is returned, which would indicate in this case an insufficient number of elements (test scores).

You can now track change in test scores:

Transformation Name New formula
Parameter: Formula type Single row formula
Parameter: Formula SUBTRACT(highestScore,lowestScore)
Parameter: New column name 'Score_range'
