JSONPath
JSONPath is a tool for quickly filtering from JSON data.

Filter JSON data
Operator | Description |
$ | 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. |
.<name> | Dot-notated child |
['<name>' (, '<name>')] | Bracket-notated child or children |
[<number> (, <number>)] | Array index or indexes |
[start:end] | Array slice operator |
[?(<expression>)] | Filter expression. The expression must evaluate to a boolean value. |
Filters are logical expressions used to filter arrays. A typical filter would be
[?(@.age > 18)]
where @
represents the current item being processed.Operator | Description |
== | 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)] |
in | left exists in right [?(@.size in ['S', 'M'])] |
nin | left does not exists in right |
subsetof | left is a subset of right [?(@.sizes subsetof ['S', 'M', 'L'])] |
anyof | left has an intersection with right [?(@.sizes anyof ['M', 'L'])] |
noneof | left has no intersection with right [?(@.sizes noneof ['M', 'L'])] |
size | size of left (array or string) should match right |
empty | left (array or string) should be empty |
