JSONPath Evaluator

Paste a JSON document on the left and a JSONPath expression on the right; the matches stream in live underneath, each labelled with its full path. Supports $, .key, [*], [n], [n:m], [n,m,...], recursive .., and [?(@.field op value)] filters with ==, !=, <, <=, >, >=, ~=, &&, ||, !, length(), and in [...]. Everything stays in this tab.

Syntax reference

Syntax	Meaning	Example
$	the root value	$
.key	child member by name	$.users
['key'] or ["key"]	child member (any characters)	$['first name']
..	recursive descent	$..price
*	wildcard — all members or elements	$.users[*]
[n]	array index (negative counts from end)	$[-1]
[n:m] / [n:m:step]	array slice (half-open)	$[1:4]
[n,m,...]	union of indices	$[0,2,-1]
[?expr]	filter expression (see below)	[?(@.active==true)]
Filter expressions — @ is the current node
@.field	member access on the current node	@.email
@.field == value	equality (also !=)	@.id == 1
@.a < b …	numeric comparison (<, <=, >, >=)	@.price > 10
@.s ~= /regex/flags	regex match against a string	@.email ~= /^a/i
length(@.field)	length of a string, array, or object	length(@.tags) > 2
@.x in [a, b, c]	membership in a literal list	@.id in [1, 3, 5]
a && b / a || b / !a	logical and / or / not	@.a==1 && !(@.b)
(expr)	grouping	@.x > (1+0)

Notes & limitations

• The evaluator runs entirely in your browser — the JSON you paste never leaves this tab.
• The path returned for each match uses the RFC 9535-ish bracket form ($['first name'][0]) for keys that aren't plain identifiers, and the dot form ($.users[0].email) otherwise.
• Numbers in filter comparisons are coerced with Number(...) on both sides, so @.price > "10" works the same as @.price > 10.
• Equality is structural: [1,2] == [1,2], {a:1} == {a:1}. Use != for negation.
• The subset of JSONPath supported here is a daily-use one, not a complete RFC 9535 implementation. Specifically out of scope: function extensions beyond length(), multiple selectors inside a single bracket pair ([0, 'foo']), and the RFC 9535 @.x is undefined predicate.
