Excel provides a way to convert the charts in an excel workbook to a webpage. To move your charts online, select the chart and use the Save as option to save the chart as a .mht/.mhtml web page. What’s more, the charts on the web page are interactive….changing values in the worksheet reflect in the chart elements. A very useful, though a little cumbersome, way of publishing chart intensive dashboards, reports and analysis on the net and sharing them with peers.
