Interpolation result: "'test1','test2'"
```
### Doublequote
Formats single- and multi-valued variables into a comma-separated string, escapes `"` in each value by `\"` and quotes each value with `"`.
```bash
servers = ['test1', 'test2']
String to interpolate: '${servers:doublequote}'
Interpolation result: '"test1","test2"'
```

Test the formatting options on the [Grafana Play site](https://play.grafana.org/d/cJtIfcWiz/template-variable-formatting-options?orgId=1).
If any invalid formatting option is specified, then `glob` is the default/fallback option.
