How can I change the price format?

This is how you can change the price format in your feed

Head over the Price column in your feed and open the Price actions:

Select an action of Number format.

 

Choose the format that you want. If you choose a format that contains a currency sign, insert the right currency (start with space):

Save the action. 

NOTE: If you can't find the Number format action, you might need to Override your column type from Text to Number.
