A few days ago I wanted to update my products list on magento importing a .csv file, but I could not upload it, the error was "Columns name "column_name1","colum_name2" are invalid", these are custom attributes.
How can I know the right format to upload my product's csv?
if I should add these columns, I try exporting the products csv and upload this file but the error is the same. Also deleting these columns but it shows me more errors
what am I missing? help me!
