Attached is a Parser for the 4E D&D Insider Compendium (only for Windows.)
All Compendium Entries but "Companions & Familiars" supported.
It creates a module folder in the directory where the program is run for whatever items you select from the Compendium (so a D&D Insider login is required.) You can download as many items at once as you select.
Use the FGPEMUtility.exe to convert resulting directory to an actual .mod file if it is not automatically created. You must manually move the module to your modules folder.
Hopefully simple enough to use without directions. Main thing is to not click the Download button until the Compendium has listed the items selected.
It does not parse Artifacts or Item Sets (but most items in Items Sets already listed separately.)
Use the multiple browsers option at your own risk. Many people have reported the application crashes when using multiple browsers.
