JMESPath Evaluator

Run JMESPath Core expressions locally against JSON and export the JSON result.

JMESPath settings

JMESPath returns exactly one JSON value, not match positions. Community extensions such as root $, let, arithmetic, or extra functions are blocked.

Input

Private by design: your data never leaves your device.

Output

Paste valid JSON and a JMESPath expression.

Good to know
The JMESPath Evaluator helps you filter and transform JSON data with JMESPath queries directly in your browser. It is useful for development, debugging, API testing, documentation, and technical reviews when data needs to be checked quickly or moved into another format.
Typical searches for this page include JMESPath tester, JMESPath query, JSON query language, AWS CLI query, and filter JSON. Processing runs locally in the browser, so sample values, internal payloads, and technical snippets are not sent to a server. JMESPath often returns `null` when a path does not exist; check field names, list projections, and filter conditions.
Typical use cases
API and payload debugging
Check JSON data with JMESPath queries from REST APIs, webhooks, logs, or browser developer tools before using it in tests, documentation, or production configuration.
Documentation and code review
Prepare data so it stays understandable and reproducible in pull requests, README files, tickets, and technical specifications.
Local inspection of sensitive data
Use the tool for internal examples, technical test values, or confidential fragments without copying them into external online services.
Tips for better results
Check the input format deliberately
Many issues come from wrong quotes, missing escapes, unexpected whitespace, or copied prefixes. Check the input first before using the result further.
Validate the result in context
Formatting and conversion do not replace domain validation. For data migrations, security values, or production configuration, always check what the result means.
How it works
Step by step
  1. 1
    Paste data
    Paste JSON data with JMESPath queries into the input field or choose a local file when the tool supports file import.
  2. 2
    Adjust options
    Choose format, variant, indentation, or output options as needed for your target system.
  3. 3
    Use the result
    Copy the output into code, tests, documentation, or configuration and review critical values before use.
Features
Runs locally in the browser
Inputs are processed on your device and are not sent to a server for processing.
For developer workflows
Useful for API data, configuration files, logs, test data, and technical documentation.
Instantly reviewable result
The result is visible immediately and can be copied or downloaded for the next step.
Frequently asked questions
Is data uploaded when using the JMESPath Evaluator?
No. Processing runs locally in the browser. Inputs are not transferred to Xoricon or another server.
Can I use the result directly?
Yes, for tests, examples, and documentation. For production data, also validate the result in the target system.
Why can an input fail?
Common causes are a wrong format, missing escapes, invalid characters, incomplete data, or a variant that does not match the expected standard.
