JSONPath Tutorial

Query and extract data from JSON documents with a compact path syntax.

JSONPath is to JSON what XPath is to XML: a small expression language for pointing at values, arrays, and nested fields without writing a parser. It shows up in API tooling, log processors, and config templating alike.

This tutorial covers the operators you'll actually use — identity, object and bracket indexing, array/string slicing, and deep scan — one exercise at a time. Each step gives you an input document and the expected result; you write the path expression and we check it.

What you'll practice (9 steps)

Identity operator($.)
Object Identifier-Index: .foo
Nested object Identifier-Index: .foo.bar
Generic Object Index: .["foo"]
Array Index: .[2]
Array/String Slice: .[10:15]
Deep scan: ..
Wildcard: [*]
Filter expression: [?(@.x<10)]
