How to extract data out of JSON?

Extracting data from JSON involves parsing and accessing specific values. In JavaScript, use JSON.parse() to convert JSON strings to objects, then access properties: parsed.user.name. Use array methods like map(), filter(), and find() to extract from JSON arrays. In Python, json.loads() parses JSON, then access with dictionary syntax: data["user"]["name"]. For complex extraction, use libraries like jq (command-line) or JSONPath (various languages) to query specific paths. Our JSON Viewer at jsonconsole.com/json-viewer helps visualize structure before writing extraction code, showing paths to reach specific values. For web applications, fetch JSON from APIs and extract needed fields programmatically. When extracting from large files, consider memory efficiency and stream parsing. Our JSON Editor shows the hierarchy, making it easy to identify exact paths to the data you need. Combine visualization with programmatic extraction for efficient JSON data handling.
