Allow product import from csv to delete fields/values
The new built in product csv export/import is great except for 1 thing - you cannot delete a value.
If the csv has an empty value (i.e. 2 commas), the merge on import ignores the value and does not overwrite existing data of the product. So if you want to delete a value (such as removing all images) it cannot be done via the import.
I would suggest that if csv contains an empty string in quotes, then it is taken as delete existing value. Or make it configurable - so on import you could say configure a value to mean delete (e.g. Have a ‘If column value equals this, merge and delete’ input field that user could configure how they want, then user could set this to say <DEL> and put that string in the csv at points where they want to delete the value. Having it configurable would allow user to use Excel to edit csv file easily.
