# Document

> The Document object provides properties and methods for reading the document being processed, including fields, pages, classification results, and source files.

`Document` represents the document currently being processed in a Custom activity script, including its fields, pages, classification results, source files, and export results.

<Info>
  Depending on which processing stages have completed, some properties may return empty values. For example, only `DocumentId` and `SourceFiles` are populated before any skill is applied. `ResultClass` is populated after a Classification skill runs. `Fields` is populated after extraction.
