This article explains how Power BI Connector handles special characters in Jira custom fields and table names.

## Custom field and table names with special characters

Power BI Connector effectively handles the occurrence of special characters to ensure the correct display of values in Power BI Desktop.

- During data extraction, the Power BI Connector detects and replaces all the occurrences of '#,.,&, and **@**' special characters in the Jira custom field and table name with an underscore (_) character.
- All the occurrences of '(,), and ?' special characters in the table name are replaced with an underscore (_) character.
- When you create or edit a connector URL and select fields, you can notice the custom field names displaying '_' instead of '#,.,&, and **@**'.
