Free JSONPath Tester Tool Online

This free online tool allows you to test and evaluate JSONPath expressions against a JSON structure.

What is JSONPath?

JSONPath is a query language specifically designed for JSON data. It allows users to navigate and extract specific data from a JSON structure using a simple and readable syntax.

How does the JSONPath Tester work?

The JSONPath Tester evaluates the provided JSONPath query against the inputted JSON content. It then displays the matching data or values based on the query, allowing users to validate and refine their queries.

JSONPath Expression

Based on the detailed JSON file provided, here are 15 JSONPath test case expressions to extract various pieces of information. These expressions will help you verify the structure and content of the JSON, ensuring your JSONPath Tester Tool works as expected.

$.LambdaTest.services[*].name

These JSONPath expressions cover a variety of queries, from simple property access to filtering based on specific criteria. They're designed to test the functionality and flexibility of your JSONPath Tester Tool against the provided JSON structure.

Advanced XPath techniques and examples

Advanced XPath techniques allow for more sophisticated querying and manipulation of JSON structures. These techniques include conditional filters, recursive descent, wildcard characters, and using script expressions. Below, I'll illustrate each of these techniques with examples to understand their capabilities comprehensively.

Conditional Filters

Conditional filters are used to extract elements based on specific conditions.
Example: Extract services with pricing models that include a free trial.

$.LambdaTest.services[?(@.pricing.freeTrial=='Yes')]

Recursive Descent

Recursive descent (..) is used to find elements anywhere in the JSON document without considering their position..
Example: Find all instances of the key description regardless of their depth in the document.

$..description

Wildcards

Wildcards (*) are used to match any element or key at a particular level.
Example: Get all name properties of tools under integrations.

$.LambdaTest.integrations.tools[*].name

Using Script Expressions

Script expressions (enclosed in ( and )) allow for the embedding of JavaScript-like code within JSONPath expressions.
Example: Filter services based on the length of their features array being greater than 3.

$.LambdaTest.services[?(@.features.length() > 3)]

Slicing

Slicing allows selecting a range of elements from arrays.
Example: Select the first two services offered.

$.LambdaTest.services[0:2]

Union

Union operator ([,]) allows for selecting multiple elements or ranges at once.
Example: Retrieve the first and last service names.

$.LambdaTest.services[0, -1].name

Filter by Nested Condition

You can use nested conditions within filters for more complex queries.
Example: Find services that have "Real Device Testing" as one of the features.

$.LambdaTest.services[?(@.features.indexOf('Real Device Testing') >= 0)]

Multiple Criteria in Filters

Combining multiple criteria in filters for refined selections.
Example: Services with free trial and include "Parallel Testing" in features.

$.LambdaTest.services[?(@.pricing.freeTrial=='Yes' && @.features.indexOf('Parallel Testing') >= 0)]

Accessing Nested Arrays

Retrieving elements from nested arrays requires precise path definitions.
Example: Extract names of tools classified under "Project Management".

$.LambdaTest.integrations.tools[?(@.type=='Project Management')].name

Using Wildcard for Array Indexes

To select all items from an array without specifying exact indexes.
Example: Get all platforms supported by each service.

$.LambdaTest.services[*].platforms[*]

These advanced JSONPath techniques enhance the ability to query and manipulate JSON data dynamically, allowing for more complex and nuanced data retrieval strategies.

JSONPath Syntax

JSONPath is a query language for JSON, similar to XPath for XML. It's used to extract and manipulate elements within a JSON structure. Here's an overview of the core JSONPath syntax elements that can be utilized in a JSONPath tester tool:

Basic Syntax

$: The root element to start the query.
@: The current node being processed.

Child Operators

. or []: Child operator to access child elements. For example,$.LambdaTest.mission accesses the mission of LambdaTest.
..: Recursive descent. Fetches descendants of the current node. For example, $..name fetches all name properties, regardless of their depth.

Array Indexes

[index]: Accesses a specific index within an array. Indexes are zero-based. For example,$.LambdaTest.services[0] accesses the first service.
[start:end]: Array slice operator to get a range of elements from an array. For example, $.LambdaTest.services[0:2] retrieves the first two services.
[-index]: Retrieves an element based on negative indexing. For example, $.LambdaTest.testimonials[-1] gets the last testimonial.

Wildcard

*: Wildcard. Matches all elements in an object or an array. For example, $.LambdaTest.* matches all elements under LambdaTest.

Filter Expressions

[?(expression)]: Filter expression. Expression must be evaluated to a boolean value. For example, $.LambdaTest.services[?(@.pricing.freeTrial == 'Yes')] finds services with a free trial.

Operators

==: Equal to.
!=: Not equal to.
<, <=: Less than, less than or equal to.
>, >=: Greater than, greater than or equal to.
&&: Logical AND.
||: Logical OR.
!: Logical NOT.

Functions

length(): Returns the length of an array or string. For example, $.LambdaTest.services.length() gives the number of services.

Multiple Names or Wildcards

[name1,name2,...]: Matches any of the specified names. For example, $.LambdaTest.support['description','contact'] fetches both description and contact under support.
[*]: Matches all elements in an array. For example, $.LambdaTest.FAQs[*].question would return an array of all FAQ questions.

Query Result

The result of a JSONPath query can be a single value or an array of values, depending on the query.

How to Use the JSONPath Tester Tool?

To use the JSONPath Tester Tool on LambdaTest, follow these step-by-step instructions:

Access the Tool:Visit the LambdaTest JSONPath Tester Tool page.
Enter JSON Data:Locate the text area labeled "Enter JSON File". Paste your JSON data into this area. This is the JSON structure you want to query with JSONPath expressions.
Input JSONPath Expression:Find the input field labeled "JSONPath Expression". Type the JSONPath expression you wish to test. This expression should query the JSON data you entered in the previous step.
Execute the Query:Look for a button labeled "Test JSONPath".Click this button to execute the JSONPath expression against your JSON data.
Review the Results:After executing the query, the tool will display the results in an output area. This section shows the data or values that match your JSONPath query, helping you validate the effectiveness of your expression.
Adjust and Re-test (Optional):If the results aren't what you expected, you can refine your JSONPath expression based on the output. Modify the JSONPath query in the input field and click the evaluation button again to see the new results. Repeat this process as needed to fine-tune your query.
Use Sample Data (Optional):This tool also offers an option to "Add Sample File" which is a pre-load example JSON data for practice and testing. This feature can be useful for learning how different JSONPath expressions behave with a known JSON structure.
