# Data normalization

Certain types of data extracted from documents are converted into a standard format so that they appear the same across all fields.

This process increases the usefulness of the data by enabling it to be grouped and analyzed more easily. It also supports integration with other applications on the ServiceNow AI Platform.

## Field types {#data-normalization__section_ggb_ysl_rxb}

The following field types are converted to support data normalization:  
{#data-normalization__table_qbs_lsl_rxb__entry__2}

| Field type | Description |
|-|-|
| Date | Standard date format. For example, YYYY-MM-DD. |
| Reference field | A field that uses a field in another table as a standard. DocIntel matches the extracted data to the standard. For example, a use case has a reference field called Vendor that points to the Name column in the Company table as the reference. When processing a document task, DocIntel extracts "Degas Dairy Products, Inc" from the document and fills the Vendor field with that value. DocIntel compares the value to the company names in the reference table and finds "Degas Dairy Products, Inc" as a match. In the document task, "Degas Dairy Products, Inc" is matched to "Degas Dairy Products, Inc" in the reference. |
| Integer | Whole number. For example, 12. |
| Decimal | Number with up to two decimal places. For example, 12.5 or 12.55. |
| Floating point number | Number with up to seven decimal places. For example, 12.0 to 12.0000000. |

{#data-normalization__table_qbs_lsl_rxb}

To set the field type, see [Create a field for data extraction](https://servicenow-prod.fluidtopics.net/YkwE4hz_XSm8lSTxJmziQw "Set up fields as part of your use case. Document Intelligence uses fields to identify and extract data from documents. Fields can be grouped to help DocIntel extract data from documents with tables, check box lists, and other logical groupings of fields.").

## Display {#data-normalization__section_uqy_ctl_rxb}

A completed data extraction field shows the converted value next to it.


You can adjust the converted date value by selecting Edit.  
Note:  
In some cases, the data extracted from the document may not be in a valid format to be converted. For example, if DocIntel read the letter O instead of a number 0 in a date field (11.12.2o23), then it would not be converted. In this case, edit the field to the correct format.

## Ambiguous data {#data-normalization__section_cxy_r3t_pbc}

If there is data in a document that can be understood in more than one way, DocIntel interprets that value based on the default selected for it in the use case configuration. DocIntel must interpret an ambiguous value in order to accurately convert it to the normalized format.

For example, a use case has a Date field, and <kbd class="ph userinput">Month first</kbd> is selected as the default order to interpret ambiguous dates. When a document containing the date 1/2/2024 is processed for the
use case, DocIntel interprets that date as January 2, not February 1, when it extracts that value and converts it.

In such cases, the user completing a document task may need to confirm or correct the conversion of ambiguous values. Depending on the field's configuration in the use case, automated document processing may be interrupted to ensure
the conversion is accurate.
