I have taken this extension out now.. Need to implement some changes. . Will be back up soon
This extension will help admin / developers to extract the overall code coverage from the developer console. All they have to do is hover over the Overall code coverage section and then click on the [Extract Data] link and then you have the csv downloaded.
You can also extract SOQL and SOSL results in the same manner from the developer console.
You can get the extension here:
