isInRange — GTM Variable Template for Condition

VARIABLES › CONDITION

isInRange CORE Condition

Direct (.tpl) Apply (.tpl)

Checks if a given value falls within a specified range (inclusive). Returns false if the value or boundaries cannot be converted to numbers.

---

When to Use This

Conditional Logic

Branch logic based on conditions — if/else, ternary, boolean gates.

Type Conversion

Safely convert between data types — strings, numbers, booleans, arrays, objects.

Comparison

Test equality, containment, and ordering between values.

Value To Check

💾 The value to check if it's within the range.

Supported formats:
  ✓ Number
  ✓ Stringified Number

Minimum Value

📉 The minimum value of the range (inclusive).

Supported formats:
  ✓ Number
  ✓ Stringified Number

Maximum Value

📈 The maximum value of the range (inclusive).

Supported formats:
  ✓ Number
  ✓ Stringified Number

Input Setup

Input Function (optional)

⚙️ Optional pre-processing function applied to the input before internal logic (e.g., convert object to string, normalize case). Internal transformations such as case handling will still apply afterward.

Result Handling

Output Function (optional)

⚙️ Optional function to apply to the result before returning it (e.g., str => str + ' €', val => val !== undefined for boolean conversion). Useful for chaining transformations on the output.

Value To Check number

💡 Type any text to see the result update live

🎯 Using special value — click input to type instead

Test with:

Falsy undefined null "" empty 0 false NaN

Truthy true 42 "hello" {} empty [] empty {a:1} [1,2,3]

Minimum Value number

Maximum Value number

🔗 Result Handling — Chain Variables

Chain apply-mode variables to the output. Each variable receives the result of the previous one.
