JSON Key Renamer
Rename one or more keys across JSON objects.
JSON Key Renamer
Rename JSON keys recursively using a key mapping object.
Expected input shape
- Top-level object must include: json and renames.
- json: any valid JSON value.
- renames: object map of oldKey -> newKey.
Rename Input
Provide a JSON object with json and renames fields.
Renamed JSON
JSON output with renamed keys.
Example input and output
{
"json": {"first_name": "Ada", "last_name": "Lovelace"},
"renames": {"first_name": "firstName", "last_name": "lastName"}
}{
"firstName": "Ada",
"lastName": "Lovelace"
