Viper uses [github.com/mitchellh/mapstructure](https://github.com/mitchellh/mapstructure) under the hood for unmarshaling values which uses `mapstructure` tags by default.
### Decoding custom formats
A frequently requested feature for Viper is adding more value formats and decoders.
For example, parsing character (dot, comma, semicolon, etc) separated strings into slices.
This is already available in Viper using mapstructure decode hooks.
Read more about the details in [this blog post](https://sagikazarmark.hu/blog/decoding-custom-formats-with-viper/).
### Marshalling to string
You may need to marshal all the settings held in viper into a string rather than write them to a file.
