Fetching column names from source irrespective of order

[Rathesh]

I want to load data from excel file to MS SQL database. Source column order may change every time.  Data has to be loaded into appropriate column in database irrespective of source column order.

I am not sure there is any straight forward way to achieve this, Talend doesn't yet support dynamic schema for Excel files as source. 
Although do check out the custom component - tFileExcelSheetInput created by @lli. It's available in Talend Exchange - see if that suits you.

Is there a way to rearrange the column order separately.
