Transform to boolean

---

Description

The Transform to Boolean processor converts string or number fields into boolean values. It supports:

• String to boolean conversion
• Number to boolean conversion
• Multiple field transformation
• In-place value modification

This processor is essential for:

• Converting data types
• Creating boolean flags
• Transforming values
• Standardizing data

---

Required input

The processor requires a data stream containing at least one string or number field to transform into a boolean.

Configuration

Transform Fields

Select one or more string or number fields to transform into boolean values. The transformation rules are:

• Strings: "true" or "1" becomes true, "false" or "0" becomes false
• Numbers: 1 or 1.0 becomes true, 0 or 0.0 becomes false

Output

The processor creates a new event containing:

• All original fields from the input event
• The selected fields with their values transformed to boolean

Example

Input Event

{
  "deviceId": "sensor01",
  "status": "true",
  "value": 1,
  "timestamp": 1586380104915
}

Configuration

• Transform Fields: status, value

Output Event

{
  "deviceId": "sensor01",
  "status": true,
  "value": true,
  "timestamp": 1586380104915
}

Use Cases

1. Data Standardization

   • Convert string states
   • Transform numeric flags
   • Standardize values
   • Create boolean flags

2. Condition Creation

   • Create boolean conditions
   • Transform thresholds
   • Convert states
   • Build flags

Notes

• Only string and number fields can be transformed
• String comparison is case-insensitive
• Numbers use 1/0 logic
• Processing is stateless
• Multiple fields can be transformed
