Creating the CSV file

An example CSV file for existing products looks like this:

"10001";"Color";"param";"Blue#Pink#Grey";"Product with filter";"0";"100"

Let's have a closer look at the fields


This is the unique code for a product.


The name of the custom field. The correct name can be found on the Custom Fields page in VirtueMart in the column named Title. This is the name used in step 3.2 when creating the custom field.


This must always be param.


The custom_param fields holds all the values you want to assign to the product, each one separated by a #.


The name of the product.


The number of products that there are in stock.


The price of the product. This field is required for the parent product otherwise the selections will not show up.

Multiple parameters

It is possible that you have multiple filter fields that you want to assign to a product, for example Color and Size. The CSV file looks like this:

"10001";"Color~Size";"param~param";"Blue#Pink#Grey~M#L#S";"Product with filter";"0";"100"

If you have 2 custom titles, there must also be 2 custom values and 2 custom parameters.
