Use the `jsonArrayContains` operator to determine whether a JSON array contains a particular item.

## Syntax

`jsonArrayContains(<jsonArrayField>, <stringField>)`

The `<jsonArrayField>` argument is a field that contains a string in JSON array format (for example, `["foo", "bar"]`). `<stringField>` is a string to check against the items of that array (for example, `"foo"`). If the item is in the array, it returns `true`; otherwise it returns `false`.

## Examples

### Filter logs where a tags array contains a specific value

```sumo
_sourceCategory=application/events
| parse "tags=*," as tags
| where jsonArrayContains(tags, "critical")
```

### Create a boolean field indicating array membership

```sumo
_sourceCategory=application/events
| parse "roles=*}" as roles
| jsonArrayContains(roles, "admin") as is_admin
| where is_admin = true
```
