How to Save Excel 2013 Worksheets as HTML Files
(Optional) If you want only the current worksheet saved in the new HTML file, select the Selection: Sheet option button.
If you want, you can have Excel add a Page title to your new HTML file by taking Step 6. The page appears centered at the top of the page right above your worksheet data.
Don’t confuse the page title with the web page header that appears on the web browser’s title bar — the only way to set the web page header is to edit this HTML tag after the HTML file is created.
