Hello All

I have added attributes of colors in Sales---> Configuration---> attributes with total 5 color values

I have to update total 1000+ Different color value in this attribute so I have done export of color attribute from Attribute page to get import format

get the below format of color attribute 

I have imported this file on Attribute import page and receiving an error message of "The record sale_management.None has the module prefix sale_management. This is the part before the '.' in the external id. Because the prefix refers to an existing module, the record would be deleted when the module is upgraded. Use either no prefix and no dot or a prefix that isn't an existing module. For example, __import__, resulting in the external id __import__.None. at multiple rows"

please guide me how to update attribute value via import file because i have many attribute that values needs to be updated on odoo 17
