Browse the formatters that convert a selected value into text in a Smart String.

A [formatter](/engine/6000.7/manual/scripting/smart-strings.md#formatters) converts the value produced by the [sources](/engine/6000.7/manual/scripting/smart-strings/sources.md) into its final text, applying logic such as pluralization, lists, or conditional output. Apply a formatter explicitly by name, or omit the name to let a formatter that supports automatic detection apply implicitly. The following formatters are available, and you can add your own.
