EDMX to XSD

Hi SDNites,

I have got a EDMX file (also have JSON) and wanted to it to convert it to XSD so that it can be used in mapping. I have tried to use online tools to convert JSON to XML and then to XSD but it is not working as JSON file has too much of description and that it not relevant for the XML / XSD. Also as the file is huge it is difficult to identify and remove the unwanted description.

Can you please advise how can this be achieved (EDMX to XSD conversion).

Regards,

Abhi
