title: Excel delete empty rows
body: <p>I want to delete rows which are completely empty. For example, I have a sheet with at least 10 rows and 5 columns. Some rows don't have a value in <code>ColumnA</code> but do in <code>ColumnB</code>. Other rows have no value in any column. How can I delete those rows with no value at all but keep those rows with a value in at least one column?</p>
