+#### Disabling Quoting for Multi-value Variables
+
+Grafana automatically creates a quoted, comma-separated string for multi-value variables. For example: if `server01` and `server02` are selected then it will be formatted as: `'server01', 'server02'`. Do disable quoting, use the csv formatting option for variables:
+
+`${servers:csv}`
+
+Read more about variable formatting options in the [Variables]({{< relref "reference/templating.md#advanced-formatting-options" >}}) documentation.
