Sandbox

Hi,

Thanks for contacting us here about this extension.

Do you have a Sandbox for me to try to load the excel file before I purchase?

The Excel files will be display in frontend as the link below:

I'm sorry we don't have any trial/limited version as our plugin are open source.
But, if you encounter any trouble of compatibility, our developer in charge can fix that for you or we can refund you.

Hope it helps!
Regards,
