The jmespath-query-executor provides a reliable way to extract specific data from complex JSON structures. By using a simplified JMESPath syntax, it avoids the risks of executing arbitrary JavaScript. You can use execute_jmespath_query to run queries, validate_query_syntax to check your query structure, and inspect_json_schema to understand your dataset's root level.
