WC Document Preview
WC Document Preview Plugin will add an extended feature to the big name “ WooCommerce ” that allows adding document preview feature on the single product page.
The plugin offers a simple meta box to add a sample product that can be previewed at the front-end. The document can easily be viewed or downloaded from the pop-up.
Please make sure you only add docs in .xls and .pdf file format since only these files are allowed to be added!!
