# JMESPath in the sandbox
Specifier: `@nodetool-ai/sandbox-jmespath`. One module, the `jmespath`
root export. Import it at the top of the body.
## search — pick values out of JSON
```js
import jmespath from "@nodetool-ai/sandbox-jmespath";
const names = jmespath.search(inputs.data, "items[*].name");
const total = jmespath.search(inputs.data, "sum(items[*].amount)");
return { names, total };
```
## Gotchas
- **Default export.** `import jmespath from "@nodetool-ai/sandbox-jmespath"`.
- **Missing paths return `null`**, they do not throw.
- **The expression is a string.** Build it carefully; do not interpolate
untrusted input into it.
