Arrays appear in workflows when dealing with lists of objects, such as order line items or customer attributes, and Array Functions enable users to extract, filter, or calculate data efficiently. These functions are particularly valuable for businesses that want to handle basic data processing exclusively in Workflows, rather than having to export data to a 3rd party service more manipulation or analysis. Array Formatter is now free to use as a standard workflow execution billed at **$0**. The workflow behavior stays the same, but you no longer incur premium execution charges when using this action. **Important:** - Array Formatter is no longer treated as a Premium Action - Workflow behavior remains unchanged - You can continue using it after a webhook or any workflow step that outputs an array --- ## **Key Benefits of Array Formatter** Using Array Functions in GHL Customer Care workflows provides numerous advantages for automation, data processing, and task efficiency. Below are the primary benefits: - **Enhanced Workflow Automation:** Automate tasks that require filtering, sorting, or calculating data without sending the data to an external 3rd party service. - **Improved Decision Making:** Extract meaningful insights from datasets in real-time. - **Reduced Manual Errors:** Automate complex calculations and data manipulations. - **Customizable Actions:** Tailor workflows to unique business needs with flexible array operations. --- ## **How to Set Up Array Formatter** The action panel now makes Array Formatter easier to understand before you save the action. When choosing an action type, you can review clearer option details directly in the dropdown and configuration panel. The updated UI includes: - action type descriptions - muted icons for action types - return type visibility - output preview or return summary messaging This helps you understand what each option is expected to return before saving the action. Follow these steps to set up and use Array Functions in a workflow: **Step 1****: Access Workflow Builder**. Open the GHL Customer Care application, navigate to the Automation tab, and create or select a workflow.  ![How to Set Up Array Formatter (image 1 of 17)](https://s3.amazonaws.com/cdn.freshdesk.com/data/helpdesk/attachments/production/155040473379/original/BNeYKRSqIiAKoO2etWq1iFcGanZGh-DEXg.png) **How to Set Up Array Formatter (image 1 of 17)** This screenshot appears in the "How to Set Up Array Formatter" section of "Workflow Action - Array Formatter".

Average: add all of the values and divide by the number of values, return the mean. Count: count the total number of values, return it. Immediately after, the guide continues: Q: What type of data can be used with Array Functions? - What this covers: Sum: add all of the values, return the total. Min: find the smallest value, return it. Max: find the largest value, return it. Average: add all of the values and divide by the number of values, return the mean. Count: count the total number of values, return it. - Next: Q: What type of data can be used with Array Functions? Full procedure: 1. Sum: add all of the values, return the total. 2. Min: find the smallest value, return it. 3. Max: find the largest value, return it. 4. Average: add all of the values and divide by the number of values, return the mean. 5. Count: count the total number of values, return it. --- ## **Frequently Asked Questions** **Q: What type of data can be used with Array Functions?** A: Array Functions work with arrays (lists) of objects or numbers. Arrays often come from triggers like form submissions, order line items, or API responses. **Q: Are Array Functions a premium feature?**  A: No, Array Formatter is no longer part of GHL Customer Care’s premium workflow actions and it is now free to use. **Q: Can Array Functions handle nested arrays?**  A: No, Array Functions are currently designed to handle one-dimensional (flat) arrays. Additional processing for nested data requires custom solutions. **Q: Can I use multiple Array Functions in the same workflow?** A: Absolutely. You can chain Array Functions together to perform complex operations. **Q: How do I debug issues with Array Functions?** A: Use the “Test Workflow” feature in the builder to view outputs and ensure proper configuration. --- ## **Related Articles** - [Custom Code in Workflows](https://docs.ghlcustomercare.com/docs/workflows/workflow-builder/workflow-action-custom-code) - [Math Operations in Workflows](https://docs.ghlcustomercare.com/docs/workflows/workflow-builder/workflow-action-math-operation) - [How to Use If/Else Conditions in Workflows](https://docs.ghlcustomercare.com/docs/memberships-and-communities/membership-courses-sites/how-do-first-time-users-set-login-password-request-forgotten-password-for-their) --- ## **Next Steps** - Review your workflows to identify areas where Array Functions can automate processes. - Explore additional premium actions, such as Custom Code, for advanced automation needs. - Ensure all users managing workflows are trained on Array Functions for optimal utilization. --- Documentation for GHL Customer Care.
