Revit Shared Parameter Viewer (RvtSPFViewer.exe) has been enhanced further. A new build #0.5.7.0 has been posted.
Revit Shared Parameter Organizer
The major enhancements in this build are readable text (.PO.txt) and spreadsheet csv (.PO.csv) file format support.
If the readable text (.PO.txt) file is opened in Notepad, all shared parameters will be readable and look very nice.
If the spreadsheet csv (.PO.csv) file is opened in Excel, the shared parameters will look nice there as well.
