Good morning. We're attempting to upload a large list

Good morning.

We're attempting to upload a large list of coupon codes. I was
thinking if the plugin didn't allow for it, I could 'insert' the values
into the wp_m_coupons table. Is that an option? What would the format of
the CSV to import be? I'm hesitant to do it at this time, because that
table is currently empty, yet we have several coupon codes entered.

Thoughts?

Thanks again SO much for your time and support.

Bob
