# Set the List Separator Character

When you create a list, the data is a just a string of items. The items in a list are distinguished from one another using a separator. The default separator is a comma.

You can set a custom separator globally (all lists) or for individual lists. The custom list separator can only be a single character, for example a single semicolon (;) or a single colon (:). If you set the separator as multi-character, the default separator will be applied.

If you set a global list separator and custom separator for an individual list, the separator set for the individual list overrides the global list separator.

After setting a new separator, the separators in existing lists are not updated and are not treated as separators anymore. You can use the **`Replace`** transformer to modify an existing list and replace all instances of the previous separator with the new separator.

1. Go to Settings → About → **Troubleshooting**.
2. In the **Server Configuration** section, click **Add Server Configuration**.
3. Add the necessary key and value.

   | Type   | Key                                           | Value                                        |
   | ------ | --------------------------------------------- | -------------------------------------------- |
   | Global | **`list.separator`**                          | Single-character separator. For example “;”. |
   | List   | **`list.<`*****`listName`*****`>.separator`** | Single-character separator. For example “;”. |

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://cortex-docs.paloaltonetworks.com/xsoar-6-administrator-guide/6.12/configure-cortex-xsoar/customize-and-configure-cortex-xsoar/lists/set-the-list-separator-character.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
