# Set the List Separator Character

Set list separator characters in Cortex XSOAR 6.12.

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 by asking a question.

Perform an HTTP GET request on the following URL with the `ask` and `goal` query parameters:

```
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=<user_goal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is what the user is ultimately trying to achieve, the reason they need the answer. Sharing it helps GitBook give you a better, more relevant answer. A goal is most helpful when it describes the outcome the user wants rather than restating the question. For example, with `ask=how do I create an API token`, a goal like `automate deployments from our CI pipeline` lets GitBook tailor the answer to that use case.

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.
