Microsoft Word 2013 supports using numerous columns in a document. Though a two-column, newspaper format makes text convenient to scan, it's not well-suited for typical reports, reference materials, title pages and many documents. To convert all or part of your document from two columns to one column, Word provides a convenient, clickable method.
Click and drag your mouse over the portion of text that you want to be a single column. Alternatively, click a starting point, hold the Shift key and click the ending position to select all text in-between. Your selection does not need to include an entire paragraph or section of the column — you can begin and end the selection anywhere.
Click the Page Layout tab to access page formatting tools.
Click Columns in the Page Setup group and select One to convert the selected text to a single column.

Once completed, only the selected text is converted, keeping the unselected text as is.
