Overview
The Randomize node is a utility node that randomly selects a single value from an input array. This powerful tool enables variety in your workflows, random decision-making, and unpredictable outcomes. Perfect for creating dynamic content, random sampling, or adding randomness to automated processes.
Key Features
- • Random Selection: Uses Math.random() for true randomness
- • Array Processing: Works with any array of string values
- • Complete Output: Returns selected value, index, and original array
- • Error Handling: Gracefully handles empty arrays and invalid inputs
- • Index Tracking: Provides the position of the selected item
- • Data Preservation: Maintains the original array for further processing
Prerequisites
Data Requirements
Understanding of array data structures and random selection needs
Use Case Planning
Strategic planning for random selection
Node Configuration
Required Fields
input
An array of values to randomly select from. Must contain at least one item. The node will pick one random value from this array using Math.random().
Examples & Use Cases
Random Greeting Selection
Add variety to automated messages
{
"input": [
"Hello!",
"Hi there!",
"Greetings!",
"Hey!",
"Welcome!"
]
}Randomly selects one greeting from the array for use in emails, notifications, or chat messages.
A/B Testing Content
Randomly assign test variants
{
"input": [
"variant-a-cta",
"variant-b-cta",
"variant-c-cta"
]
}Randomly assigns users to different test variants for A/B testing campaigns.
Random Team Assignment
Distribute tasks randomly among team members
{
"input": [
"alice@company.com",
"bob@company.com",
"charlie@company.com"
]
}Randomly assigns incoming tasks or support tickets to available team members.
Best Practices
Do's
- • Provide arrays with multiple options for true randomness
- • Handle empty array cases in your workflow logic
- • Use randomIndex when you need to track which option was selected
- • Combine with If-Else nodes for conditional random routing
- • Test your workflow with all possible random outcomes
- • Store random selections for audit trails if needed
Don'ts
- • Don't use empty arrays as input
- • Avoid assuming specific outcomes in downstream nodes
- • Don't use for cryptographic randomness
- • Avoid very large arrays if performance is critical
- • Don't forget to handle all possible random values
- • Avoid using single-item arrays (defeats the purpose)
Troubleshooting
Common Issues
Empty Array Error
Symptoms: Node fails with empty array or null input
Solution: Ensure your input array contains at least one value. Add conditional logic before the Randomize node to check array length.
Unexpected Values
Symptoms: Selected values don't match expectations
Solution: Verify the input array format is correct (array of strings). Check that template variables are properly resolved before reaching this node.
Not Random Enough
Symptoms: Same values appear frequently
Solution: This is normal with true randomness. Math.random() is pseudorandom but sufficient for most use cases. For cryptographic randomness, use a different approach.
