How to Use the JSON Path Finder

Step 1: Paste Your JSON

Paste any valid JSON into the left input panel. The tool accepts JSON objects, arrays, and nested structures of any depth. Use one of the built-in examples to get started quickly — each example loads both the JSON and a matching expression.

Step 2: Enter a JSONPath Expression

Type your JSONPath expression in the input field on the right. All expressions start with $ (the root). The tool evaluates your expression in real time as you type — no button click required.

Step 3: Read the Results

Each matching value is displayed in its own card showing:

• The resolved path (e.g., $.users[0].name) — the exact location of the value in the JSON tree
• The value type (string, number, boolean, object, array, null)
• The value itself, formatted as JSON

Step 4: Copy Individual Results

Each result card has two copy buttons:

• path — copies the resolved JSONPath string (useful for use in code)
• value — copies the matched value as a JSON string

Step 5: Copy All Results

Click Copy All to copy all matches as a JSON array of { path, value } objects. This is useful for documentation or passing results to another tool.

Step 6: Load Examples

Click any example button below the expression input to load a pre-built JSON + expression pair:

• User Names — extract all names from a users array with $.users[*].name
• Recursive Hosts — find all host values anywhere in a nested config with $..host
• Array Slice — extract a range of products with $.products[1:3].name
• Filter Expression — filter orders by status with $.orders[?(@.status == "shipped")].id

Common Use Cases:

• API development: Verify response structure by querying sample payloads
• Data extraction: Pull specific fields from large JSON blobs
• Configuration inspection: Find all values for a specific key across a deeply nested config
• Debugging: Explore unfamiliar JSON structures by querying paths incrementally
• Documentation: Discover and document the exact paths to values in an API response
• Test fixture writing: Find the paths you need to assert in test code

Tips and Best Practices:

• Start with $ — all valid JSONPath expressions begin with the dollar sign (root)
• Use $..key (double dot) for recursive search across all nesting levels
• Use [*] to iterate all elements of an array or all values of an object
• Combine segments: $.users[*].address.city drills into nested objects within an array
• Filter expressions support ==, !=, >, <, >=, <= operators
• Use [-1] to select the last element of an array
• Array slices use Python-style notation: [1:4] returns elements at indices 1, 2, 3
• Click the resolved path in any result to understand exactly where the value lives
• The syntax reference card at the bottom is always visible as a quick reminder
