This article explains how Tableau Connector Pro for Jira handles special characters in Jira custom fields and table names.

## Custom field and table names with special characters

Tableau OData connector effectively handles the occurrence of special characters to ensure the correct display of values in Tableau Desktop.

- During data extraction, the Tableau OData connector detects and replaces all the occurrences of '#,., and **@**' special characters in the Jira custom field and table name with an underscore (_) character.
- When you create or edit an OData connector URL and select fields, you can notice the custom field names displaying '_' instead of '#,., and **@**'.
- As you import the data into Tableau Desktop, Tableau uses its commonly used patterns to detect and transform your data to make it easier for you to interact with. [Learn more](https://help.tableau.com/current/pro/desktop/en-us/data_clean_adm.htm).

> 📝 - You can notice that after importing Data, the Jira custom field and table names containing the '@' character display a space ( ) character in Tableau Desktop. This is because Tableau Desktop converts non-leading and trailing underscore (_) characters in field names into space ( ) characters.
