AI JSON Query Generator
Paste your JSON, describe what you want in plain English — get a jq filter and a JSONPath expression.
The AI JSON Query Generator turns a plain-English request into a working query for your JSON. Paste a JSON sample, describe what you want to pull out, and it returns both a jq filter and a JSONPath expression that match your data's real structure — plus a one-line explanation. It's the fastest way to write a query without memorizing jq or JSONPath syntax.
- ✓Reads your actual JSON so the paths are correct
- ✓Returns both a jq filter and a JSONPath expression
- ✓Great for nested objects, arrays, and filters
- ✓Test the result in the jq Playground or JSONPath Tester
How to Use It
Paste your JSON at the top of the input, then on a new line describe what you want to extract — for example "all active users' emails" or "the total price of every order over $50". The assistant returns a jq filter and a JSONPath expression. Paste either into the matching tool to run it against your data and confirm the result.
jq vs JSONPath: Which to Use
The two output formats solve overlapping but different problems, so knowing which one fits your context saves a round trip:
| jq | JSONPath | |
|---|---|---|
| Where it runs | Command line, CI scripts, Docker pipelines | Application code — most languages have a JSONPath library |
| Power | Full filter/map/reduce transformation language | Selection only — picks values, doesn't reshape them |
| Best for | Piping and transforming JSON in shell scripts | Extracting a value inside app code (e.g. a config reader) |
| Learning curve | Steeper — its own expression language | Shallow — reads like a file path with wildcards |
When in doubt, generate both — that's exactly what this tool returns on every request, so you have the right one whichever context you end up using it in.
How to Use It
- 1Paste a representative sample of your JSON into the input — the more realistic the shape, the more accurate the generated paths.
- 2On a new line, describe in plain English what you want to extract or compute.
- 3Click Generate — you get a jq filter, a JSONPath expression, and a one-line explanation of what each does.
- 4Paste the jq filter into the jq Playground, or the JSONPath expression into the JSONPath Tester, and run it against your real data to confirm the result before using it in a script or application.
What You Can Ask For
- ▸Filter by a condition — "Every user where active is true" or "orders with a total above 100" — the query includes the select/filter logic.
- ▸Pluck a nested field — "All product names" from a deeply nested catalog, without hand-writing the path through each level.
- ▸Reshape into a new object — "For each user, just id and email" — jq map/object construction generated for you.
- ▸Aggregate values — "The sum of all amounts" or "the number of items" — expressed as a jq pipeline.
- ▸Sort or group data — "Users sorted by signup date" or "orders grouped by status" — jq's sort_by/group_by generated for you.
Tips for Better Queries
Be specific about the shape you want back, not just what to filter — "the names of active users as a plain array" produces cleaner jq than "active users." If your JSON has ambiguous or repeated field names at different nesting levels, mention which one you mean ("the top-levelid, not the nested user id"). And always paste a JSON sample that reflects your real data's edge cases — an empty array, a null field — since the generated query is only as good as the structure it was written against.
