Normalization

For many specific supported fields, Document AI also returns an entity.normalizedValue in addition to the raw extracted field obtained through the textAnchor of each entity. It normalize the literal text. Normalization often breaks the text value up into sub-fields.

This contain the data in a standardized format to reduce post processing, and enable conversion to whatever format is selected. The mentionText, representing what is literally on the document, is never changed by normalization.

Normalized fields belong to one of the following categories.

In the Google Cloud console, the normalized fields are annotated with G. For example:
