# Introduction to Data Workflow Array Operators

The [**Array operators**](/v1/docs/array-operators) let you retrieve data from a data set, add values to a data structure, and join an array of values.

## What You'll Learn

In this article, you'll get an overview of the various [Data Workflow](/v1/docs/introduction-to-data-workflow) Array operators.

## Array Operators

Below is a list of the Data Workflow Array operators with descriptions of how to use them.

| Operator | Description |
| --- | --- |
| [Array2Col](/v1/docs/array2col-operator) | Converts an array of values to an array of key/value pair objects (a column in a table). Each value in the source array becomes one key/value pair object. In the **Key Name** field, enter a key to use in the key/value pairs. The value comes from the source array of values. |
| [Get](/v1/docs/get-operator) | Retrieves data from your data set based on the value entered in the **Path** field. You can use the operator to retrieve individual values or entire rows of an array. For example, a **Path** of `[0]` retrieves the first row of your data set. A **Path** of `[0].keyName` retrieves the specified key/value pair from the first row of your data set. It's also useful for referencing [Global Variables](/v1/docs/global-variables-administration). > [!TIP] > You can use `_arg` in the **Path** field to reference the input coming into the top argument port. |
| [Includes](/v1/docs/includes-operator) | Determines if a specified value exists in the input. Then, it outputs a Boolean value. The input should be a value or an array of values. In the **Value** field, enter a value to determine if it is included in your data set. If your data includes that value, the output is **True**. If not, the output is **False**. |
| [Join](/v1/docs/join-operator) | Joins an array of values and outputs a string of those values. In the **Separator** field, enter a character that separates the values in the final string. When joining string values, the final string does not include quotation marks around each value. > [!TIP] > You can use the [Col2Array](/v1/docs/col2array-operator) operator to quickly create an array of values from a single column in a table. |
| [Set](/v1/docs/set-operator) | Lets you add values to a data structure. Connect the data structure where you want to add values to the operator's upper input port. In the **Path** field, enter the key of the key/value pair you want to create. You can use dot notation to specify index positions in an array. For example, `[0].key`. In the **Value** field, enter the value for the key/value pair you want to create. Or, leave the **Value** field blank and connect the value or structure you want to add to the lower input port. > [!TIP] > You can use `_arg` to add values based on the input coming into the top argument port. |
| [Size](/v1/docs/size-operator) | Returns the size of the structure or value passed to the component. If the input is a character string, the operator outputs the number of characters. If the input is an array, the operator outputs the number of elements in the array. |
