# From Hex Content

Translates hexadecimal bytes in text back to raw bytes. This format is used by SNORT for representing hex within ASCII text. For example, `foo|3d|bar` becomes `foo=bar`. From Hex Content lives in the **Data format** category of the `fx` menu.

## Parameter

| Parameter | Type   | Required | Default | Description                                            |
| --------- | ------ | -------- | ------- | ------------------------------------------------------ |
| Input     | string | yes      | —       | Value to transform. Previous step output or a literal. |

`Input` is the primary value (previous step output or a literal).

## Returned value
