How to download edited Excel files via Fiori

Hi all,

I want to download edited Excel files.(e.g. merged, colored, justified...etc)

At first I thought using OLE, but in WEBGUI I can not download by using OLE.

After that, I found that OLE can be used in SAPGUI or Webdynpro only.

Now,My client want to use SAP fiori and download edit excel files.

Could anyone know that how to download edited Excel files via fiori?

Please teach me.

Regards.
