# Types of fields in Channable

### Import fields

Import fields are the fields that Channable finds in your product data. These fields identify information about your products like their descriptions, prices and categories. Your import fields might have different names compared to Channable's project fields.

### Project fields

Project fields are standardized fields in Channable. We use these fields to organize your product data so that it matches what channels expect. In **Setup > Import > \[your import] > Edit mapping**, you need to map your import fields to Channable's project fields.
