Workflow Builder: Array/List Values Now Supported in Text Fields

What’s new?

The custom value picker now recognizes list-type values, such as order line items, Inbound Webhook lists or any collections of values. Instead of inserting the raw list, it opens a small inline form where you can choose which field to extract and how the list should appear with your preferred format.

How it works

When you select a list, the picker stays inside the current text field and lets you choose a field plus a format: comma-separated, bulleted, numbered, or joined with a custom separator. That builder saves those formatting rules with the custom value and renders the latest list each time the workflow runs.

How to use it

• Open the custom value picker and select a list-type value.

• Choose the field to extract, the list format, and optional empty-list fallback.

• Preview the result, then click Insert to add it at the cursor.

Why we built it

Previously, array and list values could not be rendered directly in text fields, which made this data difficult to use in emails, notes, and other workflow content. With this update, users can now insert list data into the text editor and choose how it should be displayed, including comma-separated, bulleted, numbered, or custom-separated formats.

Simple example

An Inbound Webhook sends a line_items list containing a sku field. Select line_items, extract sku, and choose Numbered list to insert each product SKU on its own numbered line.

Additional Notes

• Text, number, date, and other single-value variables keep the existing instant-insert behavior.

• List formatting appears only when the workflow detects a list-type output in the execution context.

• The preview shows how the selected field and format will appear before you insert it.
