Extracted values
About this tool
Need every email in a response, no matter how deep it hides? This extractor scans the entire document — objects, arrays, any depth — and returns every occurrence of the key you name, either with its full path, as a JSON array of values, or one value per line.
Case-insensitive matching is available for messy real-world data.
How to use it
- Paste your JSON.
- Type the key to extract (e.g.
email). - Choose an output format: paths + values, JSON array, or plain lines.
- Copy or download the result.
Useful ways to apply it
- Collecting all IDs or emails from a nested API response.
- Auditing where a config key appears across a large document.
- Extracting URLs from a sitemap-style JSON blob.
- Feeding a clean value list into another script or spreadsheet.
Frequently asked questions
Does it search nested arrays too?
Yes — every object at every depth is scanned, including objects inside arrays inside objects.
Can I match keys regardless of case?
Tick case-insensitive matching to treat Email, EMAIL and email as the same key.
What if the key holds an object?
Object and array values are included and shown as JSON.
