Copy Data from one sheet to another using header as key

Holla,


I have been trying to append multiple sheet data into a single one by sorting them with Header as a Key.

Problem : I have a worksheet with Sheets : Sheet1, Sheet2, Sheet3, Sheet4,...... Sheet(n)

Note: There is only one worksheet with multiple sheets.

Every sheet has multiple columns (not fixed) but all of them HAVE same header name but not in the same order.

Total number of rows in each sheet are not fixed.

eg.:-
Sheet1_Columns_Headers (Name, Age, ***, Roll No, Subject1, Subject2, Subject3,.....)

Sheet2_Columns_Headers (Roll No,name,***,age,subject4,subject3,subject1,subject2,......)

Sheet3_Columns_Headers (***,age,Roll No,name,subject4,subject3,subject1,subject2,......)
.
.
.


Output : I want all the data to be appended in Sheet1 with all the entries placed exactly below the appropriate columns or header titles.

I would really appreciate your help as I am at a crucial stage and badly stuck at this part.

I have also attached the worksheet.
