Frequently Asked Questions
What JSONPath syntax is supported?
Standard JSONPath syntax including dot-notation (`$.store.book`), bracket notation (`$['store']['book']`), wildcard slices (`[*]`), recursive descent (`$..*`), and filter script expressions (`[?(@.price < 10)]`).
Can I provide custom queries?
Yes. You can wrap the input as `{"path": "$.my.custom.query", "json": { ... }}` or choose from common expressions.
Is my data uploaded when I use the JSONPath & JQ Query Evaluator?
No. All processing runs entirely in your browser. Nothing is sent to a server unless you explicitly create a share link.
Does this tool work offline?
Yes. After the first visit, the PWA service worker can serve the page and run the formatter without a network connection.
What is the maximum input size?
Most tools accept up to about 5MB in the editor. Very large inputs are processed preferentially in a Web Worker and may download instead of filling the output pane.
