The trick is to identify on what row you can find a recognizable column heading and then use that information to set a "Header is n lines" variable. Based on your picture, I'll assume we are looking for "StoreDC" in column A as the column header.
LOAD RecNo() as DataStart
(biff, no labels, table is Sheet1$)
WHERE @1 = 'StoreDC'
LET vHeaderSize = peek('DataStart') - 1;
DROP TABLE FindHeaderTemp;
and now use vHeaderSize in your actual load:
(biff, embedded labels, header is $(vHeaderSize) lines, table is Sheet1$);
