Interface needed to transfer contents in a table on a web page to the Add New Product interface

The issue is that you are using an extremely unique configuration:

It is called Maya Shop. We are also using the Woo Commerce plug in for
the remaining e-commerce functions.

Two e-commerce platforms?

Considering the uniqueness and the fact that you already have a developer on this project:

  1. This question is very unlikely to apply to anyone else.
  2. The developer knows more about the project then anyone here.

It’s very unlikely that someone unfamiliar with your unique requirements could offer more insight than what your resource has already provided.

Can a custom interface be written? Certainly it can.

Are there risks and complexity? Absolutely, there is more to adding products (to either platform) than simply populating the database. Each has it’s own unique process within the code.

Any custom interface would/could bypass that code and processing. Creating any number of problems and issues that would be extremely difficult to troubleshoot.
