What this tool helps you do
Explore a JSON response using the query language commonly found in command-line and cloud tooling. A projection can pick nested fields, a filter can select matching records, and built-in functions can shape the result without writing a JavaScript program. The example selects names from active users and returns a JSON array ready for another processing step.
Format rules and limitations
The tool uses the JMESPath library’s supported language and functions, not JSONPath or arbitrary JavaScript. Invalid expressions and type mismatches return errors. Missing selections can legitimately produce null or empty arrays. The source document is not modified, and no URLs are fetched. Input depth, numeric safety and worker resources are bounded; validate important queries against the exact implementation used by the receiving command or service.
Example input
{"users":[{"name":"Ada","active":true},{"name":"Grace","active":false},{"name":"Linus","active":true}]}What should I check before relying on the output?

Is input uploaded?
This tool sends input to this site’s conversion API after you select Convert on server. Files use bounded workers and, when needed, private temporary folders deleted after processing or cancellation. No conversion history is saved. The converter does not upload files to a third-party conversion service.
