Ready. Explore the example or use the input controls to begin.
Scope and practical limits
Recursively visits object members, including objects inside arrays. Array indices are not extracted as keys. The same key in different objects produces separate entries. Duplicate keys within one object are rejected.

Using JSON Key & Value Extractor
Extract recursive object keys, values or path-aware entries with literal key filtering and exact numeric values.
- Load the example or import the primary input. Supply the second JSON input when comparing or merging.
- Choose the explicit transformation rules, then inspect the result and audit before downloading.
- Download the output, audit or exact matrix JSON. Save a project to retain editable settings.
Example
Extracting name from {"a":{"name":"Ada"},"b":{"name":"Grace"}} retains both paths and values.Questions & answers
What behavior should I check before using the output?
Recursively visits object members, including objects inside arrays. Array indices are not extracted as keys. The same key in different objects produces separate entries. Duplicate keys within one object are rejected.
Are large JSON numbers rounded?
The shared JSON parser preserves numeric source tokens. Duplicate keys and inputs beyond the stated limits are rejected. Other applications can still round numbers when they parse an export.
Is my input saved automatically?
No. Save a project or download your result before leaving. Processing is local; website ads and analytics follow the site consent and privacy settings.
