JSON Data Extractor
Effortlessly navigate and extract precise data from complex JSON structures. Whether you're debugging an API response or trying to parse deep objects, our JSONPath-powered extractor works 100% in your browser—no data ever leaves your device.
100% Private & Secure
This tool runs completely inside your browser using client-side WebAssembly and JS. Zero data is ever sent to our servers.
How to use this tool
- Paste your source JSON data into the 'Source JSON' editor on the left.
- Enter a JSONPath expression or Dot Notation in the top search bar (e.g., $.users[*].id).
- View the extracted results instantly in the right-hand panel.
- Use the quick examples above the search bar to learn common extraction patterns like filtering by price or selecting specific array indexes.
Example Usage
{"user": {"name": "Alice", "tags": ["admin", "dev"]}}["admin", "dev"] (using path: $.user.tags)
When to use this tool
- API Debugging: Extract deep properties from giant nested JSON responses without scrolling.
- Data Transformation: Quickly filter arrays of objects to obtain only the specific keys you need.
- Log Analysis: Use the recursive descent operator (..) to find all occurrences of a specific key (like 'error' or 'id') across an entire log file.
- Teams & Transcription Cleaning: Reformat complex data exports into flat, readable JSON arrays.
Frequently Asked Questions
What is JSONPath?
JSONPath is a query language for JSON, similar to how XPath is used for XML. It allows you to select and filter data within a JSON object using a standardized syntax starting with '$' for the root.
Can I filter data by value?
Yes! This tool supports filter expressions. For example, using '$.items[?(@.price > 100)]' will extract only the items from an array where the price property is greater than 100.
Is my data secure?
Absolutely. DevToolsLabs processes everything locally using your browser's JavaScript engine. Your JSON data and secret keys are never uploaded to any server.
Does it support dot notation?
Yes, you can use standard object dot notation like '$.user.profile.name' for simple extractions or bracket notation for arrays.
Built by Developers, For Developers
DevToolsLabs is engineered by a team of full-stack developers who were tired of spammy, ad-filled, server-side tools parsing our sensitive data. Every utility on this site is rigorously tested, strictly client-side (your data never leaves your browser), and built to solve real-world software engineering challenges.
