What is JSONPath and how does it work?

JSONPath is a query language for JSON, similar to XPath for XML. It uses expressions like $.store.books[0].title to navigate nested JSON structures and extract specific values. The $ symbol represents the root object, dots navigate into nested keys, and brackets access array elements or use wildcards.

What is the difference between dot notation and bracket notation in JSONPath?

Dot notation ($.store.name) is the simpler, more readable syntax for accessing keys with standard names. Bracket notation ($['store']['name']) is required when keys contain special characters, spaces, or hyphens. Both produce the same result for standard key names.

How do I extract all values from a JSON array using JSONPath?

Use the wildcard operator [*] to extract all elements from an array. For example, $.users[*].name extracts the name field from every object in the users array. You can also use specific indices like $.users[0] for the first element or $.users[-1] for the last element.

JSONPath Syntax Reference

JSONPath expressions always start with $ representing the root object. Use the table below as a quick reference.

Expression	Description	Example
`$`	Root object	`$` returns the entire document
`.key`	Dot notation child	`$.store.name`
`['key']`	Bracket notation child	`$['store']['name']`
`[0]`	Array index (0-based)	`$.store.books[0]`
`[-1]`	Last array element	`$.store.books[-1]`
`[*]`	Wildcard (all elements)	`$.store.books[*].title`
`[0:2]`	Array slice	`$.store.books[0:2]`
