JSONPath Comparison Operators — ==, !=, <, >, <=, >=

Comparison Operators in JSONPath

Comparison operators are used inside filter expressions [?()] to test element values against conditions. JSONPath supports six standard comparison operators that work with strings, numbers, booleans, and null.

Operator Reference

Operator	Name	Example
==	Equal	@.status == "active"
!=	Not equal	@.role != "guest"
<	Less than	@.age < 18
>	Greater than	@.score > 90
<=	Less than or equal	@.price <= 100
>=	Greater than or equal	@.rating >= 4.0

Example Data

{
  "products": [
    { "name": "Laptop", "price": 999, "rating": 4.5, "inStock": true },
    { "name": "Mouse", "price": 29, "rating": 4.2, "inStock": true },
    { "name": "Monitor", "price": 450, "rating": 4.8, "inStock": false },
    { "name": "Keyboard", "price": 75, "rating": 3.9, "inStock": true }
  ]
}

Examples

• $.products[?(@.price == 29)] — returns Mouse (exact match)
• $.products[?(@.price != 999)] — returns Mouse, Monitor, Keyboard
• $.products[?(@.price < 100)] — returns Mouse, Keyboard
• $.products[?(@.price > 100)] — returns Laptop, Monitor
• $.products[?(@.rating >= 4.5)] — returns Laptop, Monitor
• $.products[?(@.inStock == true)] — returns Laptop, Mouse, Keyboard

String Comparisons

String comparison uses lexicographic ordering:

$.products[?(@.name > "Laptop")]    // Monitor, Mouse (alphabetically after "Laptop")
$.products[?(@.name == "Mouse")]    // exact string match

Type Coercion

Most JSONPath implementations perform strict type comparison:

• "5" == 5 is false (string vs. number)
• true == 1 is false (boolean vs. number)
• null == false is false (null vs. boolean)

Combining Multiple Conditions

Use logical operators to combine comparisons:

$.products[?(@.price >= 50 && @.price <= 500)]       // price range
$.products[?(@.rating > 4.0 && @.inStock == true)]   // high-rated and in stock
