Assign Values to Variables Using the Set Node
This workflow assigns values to variables through the "Set" node, supporting various data types such as numbers, strings, and boolean values, with a simple and intuitive operation. It addresses the need for dynamically managing variables in automated processes, allowing subsequent nodes to flexibly call preset values, thereby enhancing the flexibility and maintainability of the workflow. It is suitable for scenarios such as data processing and conditional judgment, helping users quickly establish variable assignment logic and gain a deeper understanding of variable management and data transmission mechanisms.

Workflow Name
Assign Values to Variables Using the Set Node
Key Features and Highlights
This workflow utilizes n8n’s “Set” node to assign values to variables, supporting multiple data types including numbers, strings, and booleans. The operation is straightforward and intuitive, enabling users to quickly define and modify variable content.
Core Problem Addressed
It addresses the need for dynamically setting and managing variables within automation workflows, allowing subsequent nodes to flexibly reference these predefined values. This enhances the workflow’s flexibility and maintainability.
Application Scenarios
Ideal for scenarios requiring initialization or updating of variable values within automation processes, such as data processing, conditional logic, and configuration parameter passing. It lays a foundation for more complex automation tasks.
Main Workflow Steps
- Manually trigger the workflow start using the “Manual Trigger” node by clicking “execute”;
- Use the “Set” node to assign values to variables, including a numeric variable (20), a string variable (“From n8n with love”), and a boolean variable (true);
- After assignment, the variables are available for use by subsequent workflow nodes.
Systems or Services Involved
This workflow exclusively uses n8n’s built-in nodes “Manual Trigger” and “Set” without any external system integrations, facilitating rapid deployment and testing.
Target Users and Value
Suitable for n8n beginners or automation engineers who need to quickly build variable assignment logic. By simply setting variables, it helps users better understand and master variable management and data passing mechanisms within n8n workflows.
