Use a macro to extract the data in a chart

In Excel versions 5.0 and later, data may be retrieved from a chart, even when the data is in an external worksheet or workbook. This behavior can be useful in situations where the chart was created from or linked to another file that is unavailable or has been damaged in some way.

When the source data to a chart is lost, you can still retrieve the data from the chart itself by using a Visual Basic for Applications (VBA) macro.
