Formatting your product data

Use English when submitting the names of attributes and the values for attributes that use supported values. For example, the condition [condition] attribute uses the supported values new, refurbished and used, which must be submitted in English in order for the system to read them.

For all attributes that do not use supported values, but rather allow for free-form text, such as the title [title] or description [description] attributes, make sure that you use the same language for all attributes in a feed. Use an underscore when submitting an attribute name with multiple words (for example, image_link). Learn more about how to submit attributes and attribute values
