title: filter excel sheet
body: <p>I have an open excel sheet that I have just written to, using <code>Microsoft.Office.Interop.Excel</code>. Now I want to remove lines which have certain values in certain columns. For example, removing all the lines that have the text <code>blah blah</code> in the column called <code>col</code>. Any ideas how to do that? Thanks!</p>
