vba for - delete rows with incomplete data in a worksheet

I have searched the net - but couldn't find a right solution.

I have a workbook of data - there are columns that data entry is a must (say, columns A,B,C,D ,G,H,J ) and I would like to delete the rows with incomplete data (in range say, column A to J only ) and should not delete the entire row because in the further columns there are drop down lists and other data. This is sort of a clean-up and should be in a SUB to be called/ invoked only if required (not automatic).

The idea is to clear the range contents (column A to J only) with incomplete data then to move up the complete row of data to the empty ones (no sorting required-just in their original sequence). The worksheet has a data range from A2 down to J1001.

There may be several rows of incomplete data.. whew

many thanks
