MicroStation CONNECT Edition has a reporting tool that enables you to extract and present data from a DGN file in tabular format via report definitions. A report can be placed as a table as well as exported to Excel workbook or .csv files. Please refer to MicroStation's documentation to get started on reporting:

The reporting tool in OpenCities Map provides an option to select which feature(s) to report on from the Map Features Schema item type:
The Condition Editor will provide options to narrow the search based on property values.
