## Format of a text file preview <a href="#text-preview-format" id="text-preview-format"></a>

Text files include .txt and .json files.

## Selecting entity type handling options <a href="#text-preview-entity-type-handling" id="text-preview-entity-type-handling"></a>

From a text file preview, to select the [entity type handling option](https://docs.tonic.ai/textual/dataset-configure-redaction/textual-datasets-select-handling-type#handling-options-available) for an entity type:

1. In the results panel, click a detected value.
2. On the details panel, click the entity type handling option.\
   \
   Textual applies the same option to all entity values of that type.

From the preview, you can only select the entity type handling option. For the **Synthesis** option, you cannot configure synthesis options for an entity type. You must configure those options from the dataset details page.
