Default Column Values

Sometimes it can be helpful if default values can be stored for columns not contained in the CSV file, e.g. if there are only simple products and the column product_type would be superfluous. From version 3.8.0 on, a snippet can be used to define default values for columns not contained in the CSV file. The snippet must have the following format

{
  "default-values": {
    "catalog_product": {
      "my-column": "my-column-value"
    }
  }
}

Be aware, that the default value will ONLY be used if the CSV file does NOT contain the column. If the column is available, then always the column value will be used, even if the column is empty.
