Hey K Divya!

If understand your question you want to create an app from an excel file. That’s possible with Mendix. When you create a new app you can select the option Start from spreadsheet.

However, this only takes into account your data that means that your macros won’t be on the app and you’ll need to create the logic again. 

Here you have a similar question regarding macros: https://forum.mendix.com/link/space/integrations/questions/94874

that maybe helps you.

If you have any other doubt, please let me know.

Thanks in advance,

Emilio
