What is JSON Key Extraction?
JSON key extraction is the process of retrieving specific values from a JSON object using simple dot notation paths. Instead of manually navigating through complex nested JSON structures, you can specify a path like data.user.name to instantly extract the value you need.
This JSON path finder tool uses intuitive dot notation, which is easy to understand for developers and data analysts. Each part of the path represents a key in the JSON object path, separated by dots. For example, users.profile.email means: "In the users object, find the profile object, then extract the email value."
Our JSON key extractor automatically handles JSON array keys, deeply nested structures (20+ levels), and returns the exact value, object, or array found at the specified path. Whether you're working with API responses, configuration files, or data exports, this tool makes JSON field exploration quick and effortless.
How to Extract Keys from JSON Online
Step 1: Input Your JSON
Paste your JSON data into the input field on the left. You can use any valid JSON structure, from simple objects to deeply nested configurations with multiple levels of nesting. The tool handles JSON of any complexity.
Step 2: Enter Your JSON Key Path
In the "Key Path" field, enter the JSON path to the value you want to extract using dot notation. Here are some examples of JSON key paths:
data.user.name- Extract keys from nested JSON user objectusers.profile.email- Find key paths in JSON profile dataitems.price- Get all paths in JSON for pricing dataresponse.data.items[0].id- JSON path finder for array elements
Step 3: Extract and View Results
Click the "Extract Value" button or press Ctrl+Enter (Cmd+Enter on Mac). The JSON key extractor will parse your JSON, navigate to the specified JSON object path, and display the extracted value. The result shows the exact type (string, number, object, array, etc.) and the value itself, which you can copy to your clipboard with one click using JSON path click-to-copy functionality.
Understanding Dot Notation
Dot notation is a simple way to access nested properties in JSON objects. Each dot separates a level in the object hierarchy. The path is read from left to right, with each segment representing a key in the JSON structure.
Example 1: Simple Nested Object
JSON:
{
"data": {
"user": {
"name": "John Doe"
}
}
}Path: data.user.name
Result: "John Doe"
Example 2: Array Access
JSON:
{
"items": [
{"id": 1, "price": 19.99},
{"id": 2, "price": 29.99}
]
}Path: items[0].price
Result: 19.99
Note: Use [0] to access the first item, [1] for the second, and so on.
Example 3: Deep Nesting
JSON:
{
"response": {
"data": {
"items": [
{"id": 101, "name": "Item 1"}
]
}
}
}Path: response.data.items[0].id
Result: 101
What Gets Returned?
The JSON Path / Key Extractor returns the exact value found at the specified path, preserving its original type and structure:
- Primitive values: Strings, numbers, booleans, and null are returned as-is
- Objects: Complete objects are returned with all their properties intact
- Arrays: Arrays are returned in their entirety, preserving all elements
This means if your path points to a string, you get a string. If it points to an object, you get the full object. If it points to an array, you get the complete array. The tool never wraps or modifies the extracted value.
Explore Related JSON Tools
While extracting keys from JSON online is powerful, you might also need to format, validate, or compare your JSON data. Here are our other free JSON tools that work great alongside this JSON path finder:
JSON Formatter
Format and beautify your JSON with proper indentation and structure. Perfect for making JSON readable.
Format JSON →JSON Validator
Check if your JSON is valid and identify syntax errors. Essential before extracting keys from JSON.
Validate JSON →JSON Minifier
Compress your JSON by removing whitespace. Great for production-ready JSON after key extraction.
Minify JSON →JSON Diff / Compare
Compare two JSON objects and see the differences. Useful when tracking changes in JSON structures.
Compare JSON →Frequently Asked Questions
What is JSON dot notation?
JSON dot notation is a simple way to access nested properties in JSON objects by chaining keys with dots. For example, data.user.name means "extract keys from nested JSON user object inside the data object."
How do I access array elements?
Use square brackets with an index: items[0] accesses the first element,items[1] the second, and so on. You can combine this with dot notation:items[0].price gets the price of the first item.
What happens if the path doesn't exist?
If the specified path doesn't exist in your JSON, the tool will display "No value found at the specified path." Make sure your path matches the structure of your JSON data exactly.
Is my JSON data safe?
Yes! All processing happens entirely in your browser. Your JSON data never leaves your device and is never sent to any server. This tool works completely offline and respects your privacy.
Can I extract keys from deeply nested JSON structures?
Absolutely! The JSON key extractor supports JSON nested structures with 20+ levels of nesting. Simply chain the keys with dots to navigate through any depth of nesting, like level1.level2.level3.value.
