excel - Remove empty rows in excel via connectionString

Question

I am using Connection String to connect an Excel file to read data.

I use this query:

SELECT * FROM [SHEET1$]

My problem is when user set a value in a new row and later delete it, my query returns me the row but empty.

I want my select to ignore this rows without doing something like ".... WHERE COLUMN1 <> ''
AND COLUMN2 <> '' ...." and so on. Its possible remove empty rows without provide all column list?

Thanks!
