jmespath
JMESPath (pronounced “james path”) allows you to declaratively specify how to extract elements from a JSON document.
In web scraping, jmespath is a powerful tool for parsing and reshaping large JSON datasets. Jmespath is fast and easily extendible following it's own powerful query language.
For more see the Json parsing introduction section.
Example Use
```python import jmespath
data = { "data": { "info": { "products": [ {"price": {"usd": 1}, "_type": "product", "id": "123"}, {"price": {"usd": 2}, "_type": "product", "id": "345"} ] } } }
easily reshape nested dataset to flat structure:
jmespath.search("data.info.products[*].{id:id, price:price.usd}", data) [{'id': '123', 'price': 1}, {'id': '345', 'price': 2}] ```
