LSMW Idoc audit log saying -> Incorrect File Structure against Customer Master load

Incorrect File Structure against Customer - General Tab - See E41 - Error General for correct Structure

I am trying to figure out why this error is occuring.

Since I have been provided with load file to upload data to sap system.

I have put data in the order they have provided in the excel file.

In LSMW IDoc I get error such as above.
