Excel add-in

Prefer to stay in Excel?

The DDC Excel add-in opens RVT, IFC and DWG data directly in a workbook. The Excel → Revit plugin writes edited parameters back into the model.

What you get

One flat table. Every parameter.

No filtering, no lost properties. Each row is an element, each column a parameter, readable by anything that reads a spreadsheet.

Three ways to run

From one click to a nightly pipeline.

Start with the UI on a single file. When it works, the same converter runs in a script, an n8n workflow or an AI agent. No new tool to learn.

  1. 01

    DDC UI

    Pick a folder with one or many projects, press Start. Excel files with every element and parameter appear next to the originals.

    1  Select folder   C:\Projects\2  Press  [ Start ]✓  Tower.xlsx · Tower.dae✓  Hospital.xlsx · Hospital.dae
  2. 02

    Command line

    One line in CMD or PowerShell. Options for bounding boxes, rooms, schedules and sheets to PDF.

    > RvtExporter.exe "C:\Projects\Building.rvt"    complete bbox schedule sheets2pdf > Get-ChildItem "C:\Projects\*.rvt" |    ForEach-Object { & RvtExporter.exe $_.FullName }
  3. 03

    Pipelines & AI agents

    Call it from Python, n8n, CI or a coding agent. Convert → validate → classify → estimate, on a schedule.

    import subprocesssubprocess.run([r"C:\DDC\RvtExporter.exe",    r"C:\Projects\Building.rvt",    "complete", "bbox", "schedule"])

Prompt for Claude Code, Cursor or Copilot, from the README

“I have Revit files in C:\Projects. Using DDC RvtExporter.exe located at C:\DDC\, convert all .rvt files to Excel with bounding boxes, then create a Python script that reads the XLSX files and generates a summary report of all wall types and their volumes.”

Revit and IFC reports that used to take me almost weeks to create are now updated in just a few minutes. I was able to quickly understand what the DataDrivenConstruction did and thus extend and modify it to fit projects. The DataDrivenConstruction team showed me examples of blocks and scripts that can automatically generate PDF, XLSX, and DOCX files that mark errors/defects in the model. Additionally, we also now do automatic checks for IFC structure, file naming, etc.

As a data scientist, I use data every day in every topic and field and think that data can appear in one format to make it easier to use and explore. After I tried the DDC converter, it became the only solution for me to manage and convert all BIM documents. Thanks to DataDrivenConstruction, I can now work with all IFC and Revit files automatically without having to upload files to the server.

DataDrivenConstruction products revolutionize data management in construction! Their IFC and RVT to Excel converters enable smooth data analysis and extraction, optimizing project management and documentation. A powerful, user-friendly solution for construction professionals (translated from French)

Nicolas MerotIngénieur BIM · Caeli Ingénierie

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. Data Driven Construction 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.

FAQ

Converter questions.

Something else? Ask us directly

Are the converters free?

Yes, for personal and research use. The Community version of the converters is free to download without registration. The workflows, Python scripts and documentation on GitHub are MIT-licensed. The converter binaries themselves are proprietary: production use in a company, commercial SaaS or processing files for third parties needs a commercial licence.

Do I need Revit, AutoCAD or an Autodesk licence?

No. The converters read RVT, IFC and DWG files directly: no Autodesk licence, no Revit installation, no plugins, no API keys and no cloud upload.

Can I convert RVT to IFC without Revit?

Yes. RVT2IFCconverter reads Revit 2015–2026 files directly and writes IFC 2x3, IFC 4, IFC 4.3, IFCXML and IFCZIP. No Revit installation and no Autodesk licence are needed, and it runs offline from the UI, the command line or a pipeline.

Is there an online Revit or DWG converter?

We deliberately ship offline converters instead of an upload service. You download them once and convert on your own computer or server, so drawings and models never leave your company. For many files at once, run them in batch from the command line, Python or n8n.

Is it a Revit version converter? Can I open a Revit 2025 or 2026 file without upgrading Revit?

You can read it. The converters take any Revit file from 2015 to 2026 and export all elements and parameters to Excel, geometry to DAE, sheets to PDF and the model to IFC, without opening Revit. They do not save the file back as an older .rvt version.

Can I convert RVT to DWG, DWG to IFC or IFC back to Revit?

Not with these converters. They turn RVT, IFC and DWG into open data: Excel and CSV tables, DAE geometry, PDF sheets and, for Revit, IFC 2x3, 4 and 4.3. They do not write DWG or RVT files. To bring an IFC model into Revit, open or link it in Revit itself; to work with its data, convert it to Excel with the IFC converter.

Which operating systems are supported?

Windows and Linux. Run them from the DDC UI, from CMD or PowerShell, from Python, n8n or any tool that can start a process, including CI pipelines and AI coding agents.

Which file versions can I convert?

The free downloads on this page cover Revit 2015–2024, IFC 2x3 (IFC 4.1–4.x in the newer build) and AutoCAD DWG 1983–2023. The latest builds on GitHub support Revit 2015–2026, IFC 2x3 to 4.3 and DWG 1983–2026.

Does my project data leave my computer?

No. Conversion runs fully offline on your own machine or server. Nothing is uploaded, which is why the converters are used for confidential projects and inside closed company networks.

What is the difference between the free and the ad-free version?

In the free version, advertisements appear in the conversion results. The ad-free version removes them and supports the latest CAD (BIM) formats. It comes with a 30-day full refund guarantee, if you are not satisfied, tell us and we refund, no questions asked.

Can I convert hundreds of files automatically?

Yes. Point the converter at a folder or call it in a loop from PowerShell, Python or n8n. Ready-made n8n workflows on GitHub handle batch conversion with validation and reporting, classification, cost estimation and HTML quantity takeoffs.
