Elements and their properties in one XLSX

We have not yet published a DGN sample file with its output, so this page lists what is exported instead of showing a table.

  • XLSX with the elements and properties of the DGN file.
  • Batch conversion of whole folders.

Output files

XLSX
Elements of the DGN file and their properties, one table.
Geometry
Not exported. Data only.
Batch
Whole folders from the GUI, PowerShell or Python.

Convert from the window, PowerShell or Python

Same converter, same output. Start with the window, then put the command in a batch file, a script or an n8n workflow.

In the window

  1. Install the Microsoft Visual C++ Redistributable 2015-2022 (x64) if it is missing.
  2. Unzip the download.
  3. Choose DGN files in the GUI.
  4. Press Convert.
PowerShell, in the unzipped folder
# XLSX next to Bridge.dgn
> DgnExporter.exe "C:\Projects\Bridge.dgn"
Python, every file in a folder
import subprocess, pathlib
for f in pathlib.Path(r"C:\Projects").glob("*.dgn"):
    subprocess.run(["DgnExporter.exe", str(f)], check=True)

Reviews

Most civil design files are basically data prisons. Loads of useful info—alignments, surfaces, quantities—just sitting there, locked inside formats that were never meant to play nice with anything outside their original software. I’ve wasted way too much time trying to answer simple questions like 'how many manholes are in this job?' or 'what’s the volume by phase?'—only to find out the data’s buried five layers deep in a DWG or DGN. DataDrivenConstruction fixes that. Their converters crack open these closed formats and give you structured data you can actually use—in Power BI, in Excel, or even in an LLM prompt if you're doing something fancy. It's not flashy, but it’s insanely useful. If you’re trying to move beyond screenshots and PDFs and actually use your design data, this is the kind of tool that makes it possible. It’s the difference between guessing and knowing. And honestly, it’s saved me more than a few Saturday mornings.

Questions about DGN to Excel

All questions

Which DGN versions are supported?

MicroStation DGN v7 and v8.

Do I need MicroStation?

No. The converter reads DGN files without MicroStation or a Bentley licence.

Can you convert DGN v8 to v7?

No. We extract data from DGN files; we do not convert between DGN versions.

Does it export 3D geometry?

No. DGN files become an Excel table only. There is no 3D, IFC or PDF output from DGN.

Is this an online converter?

No. It is a download that runs on your Windows or Linux computer, or on your own server. Files are never uploaded, so confidential projects stay on your machine.

Is it free for commercial work?

The Community version is free for personal and research use. Commercial use, processing files for third parties, SaaS or redistribution needs a commercial licence. Request a quote on the licence page.
