JMESPath Query FAQ
What is JMESPath?
JMESPath is a query language for JSON that enables you to extract and transform elements from JSON documents. It provides more advanced data transformation capabilities than JSONPath, including filtering, mapping, and aggregation functions.
How is JMESPath different from JSONPath?
