+# subList(<key>, <start_index, inclusive>, <end_index, exclusive>)
+
+The `subList()` function extracts a sublist from a list field in an event. It takes the following arguments:
+
+- A JSON pointer to a list field in the event
+- A start index (inclusive)
+- An end index (exclusive)
+
+The function returns the portion of the list between the specified start and end indexes. If the end index is `-1`, the function extracts elements from the start index to the end of the list.
+
+
+## Examples
+
+The following examples show how the `sublist()` function works.
+
+### add_entries processor
+
+You can use `subList()` in the `add_entries` processor, as shown in the following example.
+
+For example, the function will use the following input to extact a sublist:
+
+```
+input: {"my_list": [ 0, 1, 2, 3, 4, 5, 6]}
+```
+
+Then, the following configuration uses the `add_entries` processor to extract a sublist from `my_list`, starting at index 1 and ending before index 4: 
+
+```yaml
+add_entries:
+  entries:
+    - key: "my_list"
+      value_expression: '/subList(/my_list, 1, 4)'
+      overwrite_if_key_exists: true
+```
+{% include copy-curl.html %}
+
+The following output shows the resulting list after extracting elements from index 1 to 3 and overwriting the original list:
+
+```
+output: my_list: [1, 2, 3]
+```
+
+### Specific ranges
+
+Each of the following examples demonstrates how the `subList()` function extracts a specific range of elements from a list.
+
+The following example extracts elements from index `0` to `2` (excluding index `3`), resulting in the first three elements of the list:
+
+```json
+{
+  "event": {
+    "/my_list": [0, 1, 2, 3, 4, 5, 6]
+  },
+  "expression": "subList(/my_list, 4, -1)",
+  "expected_output": [4, 5, 6]
+}
+```
+{% include copy-curl.html %}
+
+The following example uses `-1` as the end index, which tells the function to include all elements from index `4` to the end of the list:
+
+```json
+{
+  "event": {
+    "/my_list": [0, 1, 2, 3, 4, 5, 6]
+  },
+  "expression": "subList(/my_list, 4, -1)",
+  "expected_output": [4, 5, 6]
+}
+```
