JSON flattener
Flatten nested JSON into unambiguous JSON Pointer keys.
Result
Add your input, then select Flatten JSON.
How to use it
Paste nested JSON. Each leaf becomes a property named by its JSON Pointer, including array indexes.
What to keep in mind
The output uses escaped pointer keys rather than dot notation, so keys containing dots or slashes stay distinct.
Up to 2 MB per input, with smaller limits for complex operations. Clear removes the current input and result. Numbers use JavaScript precision; unsafe integers are rejected.
