Hi Krish,
By using “XrmToolBox” you can get the list of entities with all the attributes in it .
Kindly follow the steps:
1. Open XrmToolBox.
2. Establish the connection with the your relevant organization.
3. Open “Metadata Document Generator”.
4. Give the Document Format , file path (where you want to save the excel sheet),

Hope this will work.
