Re: how to export expressions from all reports into excel ?
If you are using Qlikview 10, another option would be to generate the project file associated with the dashboard. This is QlikView's version control system and generates a folder containing XML descriptions of all objects associated in the document.
I create the folder, then use a qlikview script to loop back and import information relating to the objects.
To create the project files (in QV10) create a document folder the same name and folder as your dashboard but with the suffix -prj.
EG for dashboards/aDashboard.QVW the folder name would be dashboards/aDashboard-prj/
Next time you reload the folder will be populated with 1 xml for each object, sheet etc in your dashboard. I then use this to get metadata about my applicaation.
The following scriptm for example returns all expressions / charts back into a qlikview document
