## What this tool does

The JSON Path Finder is a free tool that parses JSON and lists its property paths, so you can reach a nested value without counting brackets by hand. Paste JSON, click Find All Paths, select a result, and copy its JSONPath or access code. For example, user.address.city becomes $.user.address.city.

Each result shows its value type and a short preview. Selecting a path reveals JavaScript optional chaining, a TypeScript assignment, a Lodash _.get() call, and JSONPath syntax. This is useful when exploring an unfamiliar API response and looking for a field such as posts[0].id.

The tool processes your JSON in the browser. Your input is not uploaded to a server, and no signup is required.

## How to use it

1. Paste or type your JSON into the input box, or pick one of the Simple Object, Nested Array, or Complex example buttons.
2. Click Find All Paths (or press Ctrl+Enter) to traverse the document and list every path.
3. Scan the results list, where each entry shows a type badge, the path, and a value preview.
4. Click a path row to open the Access Code panel for that property.
5. Copy the form you need: JavaScript optional chaining, TypeScript, Lodash _.get(), or JSONPath.
6. Press Ctrl+L at any time to clear the input and start over.

## What you can use it for

- Finding the path to a deeply nested field in a large API response without manually counting brackets.
- Generating optional-chaining access code so a missing intermediate property does not throw a runtime error.
- Writing Lodash _.get() calls when working in a codebase that already uses Lodash for safe property access.
- Building JSONPath queries for tools, log processors, or libraries that accept JSONPath expressions.
- Exploring an unfamiliar third-party payload to understand its shape before writing a type definition.
- Quickly checking the data type of every value in a JSON object during debugging.

## Key features

- Recursively traverses objects and arrays and reports the type of every value.
- Generates JavaScript optional chaining, a TypeScript assignment, a Lodash _.get() call, and JSONPath for a selected property.
- One-click copy for individual paths and generated access code.
- Keyboard shortcuts for analyzing (Ctrl+Enter) and clearing (Ctrl+L).

## Frequently asked questions

### What is a JSON path finder?

A JSON path finder is a tool that reads a JSON document and tells you the exact path to reach any value inside it, such as data.user.address.city. It saves you from manually counting nested objects and array indices when you need to access a specific field in code.

### How do I find the path to a nested value in JSON?

Paste your JSON into the tool and click Find All Paths. It lists the property paths. Select a result to get copy-ready JavaScript, TypeScript, Lodash, or JSONPath code; use the button on a row to copy its dot-notation path directly.

### Is my JSON data sent to a server?

No. The JSON Path Finder parses your data entirely in the browser using JavaScript. Nothing you paste is uploaded or stored, so it is safe to use with API responses that contain sensitive fields.

### What is the difference between JSONPath and dot notation?

Dot notation like user.name is plain JavaScript property access. JSONPath is a query language, written with a leading $, used by libraries and tools to select values from JSON, similar to how XPath selects nodes in XML. This tool gives you both forms for any property.

### Why does the tool generate optional chaining (?.) code?

Optional chaining stops your code from throwing if an intermediate property is missing. Instead of crashing on undefined, the expression simply evaluates to undefined, which makes the generated access code safer for unpredictable API data.

### Does the JSON Path Finder work with arrays?

Yes. It traverses arrays as well as objects and generates index-based paths like posts[0].id. Each item gets its own path and a badge showing that value's type.
