Excel add-in
The DDC Excel Add-in 2.0 opens RVT, IFC and DWG data directly in a workbook. For Excel 2016 or newer on Windows 10/11, 64-bit. The Excel to Revit add-in writes edited parameters back into the model; it is sent on request.
How the add-in works Older guideWhat you get
No filtering, no lost properties. Each row is an element, each column a parameter, readable by anything that reads a spreadsheet.

Windows 10/11 64-bit · runs offline · no Revit or AutoCAD installation needed
Three ways to run
Start with the desktop app on a single file. When it works, the same converter runs from a script, an n8n workflow or an AI agent.
Start the app, pick a file or a folder, run it. The result appears in a new folder next to the source file.
1 Pick C:\Models\Project.rvt2 Press [ Start ]✓ GLB · JSONL · IFC4 next to the file
Run the executable from the unzipped folder in PowerShell or a batch file. The 2.0 command line is documented on the download page.
> RVTconverter.exe "C:\Models\Project.rvt"-o "C:\Out\Project" --properties --ifc> RVTconverter.exe --help
Open the result tables in Excel, Power BI, Python or the free DDC Data Viewer, or start the converter from n8n, a script or a coding agent.
Project.glbproperties.jsonlProject.ifc
Prompt for Claude Code, Cursor or Copilot
“I have Revit files in C:\Models. Using DDC RVTconverter.exe located at C:\DDC\ (run it with --help to see the options), convert each .rvt file to properties JSONL, then write a Python script that reads the output and prints a summary of all wall types and their volumes.”
Use the data
Filter, pivot and sum quantities in the tool everyone already has.
Dashboards across all projects, refreshed from the converted tables.
Ask questions about a model in plain language, with pandas under the hood.
Group, validate and forecast with a few lines of Python.
Visual pipelines that convert, check and report without manual steps.
Quantities straight into BOQs, estimates and the 3D viewer.
n8n workflows · MIT
Import into n8n, point at your folder, run. Each workflow is plain JSON you can read, change and extend, or let us adapt it to your standards.
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.
Daniel GloberBIM Manager · SCHOLZE-THOST GmbHAs 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.

Their IFC and RVT to Excel converters enable smooth data analysis and extraction, optimizing project management and documentation.

Nicolas MerotIngénieur BIM · Caeli IngénierieMost 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.

Yes, for personal and research use. The Community version of the converters is free for non-commercial use: personal learning, research and teaching. You enter your e-mail on cadbimconverter.com and the download starts at once. The ddc-tools, workflows and documentation on GitHub are MIT-licensed. The converters themselves are proprietary: use in a company, for clients or in a product needs a licence on request.
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.
Yes. The DDC RVT to IFC converter reads RVT and RFA files from Revit 2019 to 2027 directly and writes IFC4 in three profiles: full, coordination and geometry. No Revit installation and no Autodesk licence are needed, and it runs offline from the desktop app or the command line.
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.
You can read it. The Revit converters read RVT and RFA files from Revit 2019 to 2027 without opening Revit. They write geometry as GLB, properties as JSONL and the model as IFC4, and a flat Excel table with the free ddc table tool. They do not save the file back as an older .rvt version.
Not with these converters. They turn RVT, IFC and DWG into open data: Excel, CSV, JSONL and SQLite tables, GLB geometry, DXF and SVG drawings and, for Revit, IFC4. 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. Writing edited parameters back into a Revit model is the job of the Excel to Revit add-in, available on request.
Windows 10 and 11, 64-bit. Use the desktop app, or run the executable from CMD or PowerShell, from Python, n8n or any tool that can start a process.
DDC Converters 2.0 read Revit RVT and RFA files from 2019 to 2027, IFC 2x3 and IFC4 (also zipped) and AutoCAD DWG from R13 to 2018.
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.
The software is the same. In the Community version an ad page may open after a conversion. The ad-free licence removes it and adds support by e-mail and updates. Terms and the right of withdrawal are on the licence page of cadbimconverter.com.
Yes, with a licence for batch and server use. Call the converter in a loop from PowerShell, Python or n8n. Ready-made n8n workflows on GitHub cover batch conversion with validation and reporting, classification, cost estimation and HTML quantity takeoffs; they were written for earlier converter builds, so check the options against the 2.0 command line.
