Xml mac question

Hi,
I want to built a solution as such:
In ASP.NET app, when online, save a form data into XML (this is done), the form is also saved as XLS file with built in macros (optional).
User is offline (on a PC or MAC – this is very important requirement), opens the XLS file, edit the file, save it and upload to server when online.
The server opens the XLS file (no automation here), read the updated info, save the data to an XML file format or dataset or database.

I hope I am being clear…please let me know if this is a right product to have.

Thanks for looking!

Yes. Aspose.Excel can serve your need on your solution.

Could you please post a spreadsheet created on MAC? We don’t have a MAC on hand so we need to check it. Thank you.
