Frequently asked questions
- What is JSONPath?
- A query language for JSON, similar in spirit to XPath for XML. $ refers to the root, . or [] navigate into objects, [*] matches every element of an array, and [?(@.price < 10)] filters by a condition.
- What JSONPath syntax is supported?
- The full syntax implemented by jsonpath-plus, including wildcards ([*]), recursive descent (..), array slices ([0:2]), and filter expressions ([?(@.price < 10)]).
- Why does each match show a path like $['store']['book'][0]['author']?
- That's the exact, unambiguous path to that specific match in the document — useful when a wildcard or filter matches more than one value and you need to know exactly where each one came from.
- Is my data uploaded anywhere?
- No — the query runs entirely in your browser. Nothing is uploaded.
How GetByteRush compares
Most free tools for this online work the same way: you upload your file to their server, wait, then download the result — which means your file (and often your email, for a "free" account) sits on someone else's infrastructure. Here's the actual difference:
| Feature | GetByteRush | Typical online tools |
|---|---|---|
| Data ever leaves your device | No — evaluated in this tab | Yes, uploaded to process |
| Shows the exact path of each match | Yes | Varies — some tools only show matched values |
| Account required | Never | Often, past a certain usage level |
