1. What's it?

JSONPath is a tool for quickly filtering from JSON data.





The root element to query. This starts all path expressions.


The current node is being processed by a filter predicate.


Wildcard. Available anywhere a name or numeric are required.


Deep scan. Available anywhere a name is required.


Dot-notated child

['<name>' (, '<name>')]

Bracket-notated child or children

[<number> (, <number>)]

Array index or indexes


Array slice operator


Filter expression. The expression must evaluate to a boolean value.

Filter Operators

Filters are logical expressions used to filter arrays. A typical filter would be [?(@.age > 18)] where @ represents the current item being processed.




left is equal to the right (note that 1 is not equal to '1')


left is not equal to the right


left is less than right


left is less or equal to the right


left is greater than right


left is greater than or equal to the right


left matches regular expression [?(@.name =~ /foo.*?/i)]


left exists in right [?(@.size in ['S', 'M'])]


left does not exists in right


left is a subset of right [?(@.sizes subsetof ['S', 'M', 'L'])]


left has an intersection with right [?(@.sizes anyof ['M', 'L'])]


left has no intersection with right [?(@.sizes noneof ['M', 'L'])]


size of left (array or string) should match right


left (array or string) should be empty
