Hello Indrė,

Do you use the group by feature or do you filter the categories you want to export ?

When you select entries that are grouped by, they are exported with a particular lay-out.

Maybe the CSV format can't handle it.

Hope it helps.

Yes, I do group products as you described in order to select faster what I need, but Odoo does not let to export it to csv. I wonder if there is another way to select products
