Online JSONPath Finder & Evaluator
Inspect complex JSON hierarchies, extract node JSONPaths, and test query expressions in real time — 100% in your browser.
How It Works
Fast, secure, browser-native JSON processing in 3 simple steps
Paste JSON Document
Paste your JSON data into the editor or load a sample document.
Navigate or Filter Tree
Click any node in Tree View to see its live JSONPath in the breadcrumbs bar.
One-Click Copy Path
Click the JSONPath badge to copy the exact expression to your clipboard.
Navigate and Extract Properties with Standard JSONPath (RFC 9535)
Modern API testing, logging pipelines (Datadog, Elastic, Grafana), and infrastructure automation (Kubectl, Terraform, GitHub Actions) frequently require precise JSONPath expressions to extract specific metrics from massive JSON responses. Writing path selectors manually for deeply nested arrays and dictionaries is error-prone.
JSONForge's JSONPath Finder & Evaluator lets you interactively explore JSON structures with collapsible tree nodes, real-time search filtering, and automatic path tracking. Simply click or hover over any property to instantly view and copy its normalized JSONPath expression (e.g. $.store.inventory[3].author).
🎯 One-Click Path Copy
Hover over any node in Tree or Code view to instantly copy its exact RFC 9535 JSONPath expression.
🌳 Virtualized Tree Explorer
Explore large multi-megabyte payloads with 50,000+ nodes smoothly without browser lag or memory spikes.
🔒 Complete Privacy
All JSONPath evaluations and tree rendering happen locally in your web browser with zero server uploads.
JSONPath Syntax Quick Reference
| Expression | Description | Example Match |
|---|---|---|
| $ | Root object / element | The root JSON container |
| .key or ['key'] | Child property selector | $.store.location |
| .. | Recursive descent (all descendants) | $..author (all authors anywhere) |
| * | Wildcard for all elements/properties | $.store.inventory[*] |
| [0] or [-1] | Array index (first or last element) | $.store.inventory[0] |
| [?(@.price < 20)] | Filter expression by condition | Books priced under $20 |
