CAD Drawing to Excel converter: entities, layers and block attributes as a table, without AutoCAD®

DWG drawings from R13 to 2018 become one row per entity, keyed by the DWG handle, in XLSX, CSV and JSONL, plus a DXF and an SVG of the drawing. Our sample drawing DDC-Sample-House.dwg (a fictional house: plans, section, elevations, schedules) gives 8,435 rows and 95 columns.

One model, every parameter as rows

Rotate the model or zoom into the drawing and click any element: on the right you see the row the converter wrote for it, with every parameter. The same table holds all elements at once, ready for Excel, BI or code.

Sample: DDC-Sample-House.dwg, a fictional house drawn by DataDrivenConstruction for this demo (download the DWG). Converted on our build machine with the DDC DWG to Excel 0.4.1; every figure here is counted from that output (attribution). It also writes the same rows as CSV and JSONL, and the drawing as DXF and SVG.

What you get

One row per drawing entity, keyed by its handle

Lines, polylines, blocks, dimensions and texts each get a row with layer, linetype, geometry values and block attributes as columns.

Fig. 3. dwg2excel.exe writes a new folder per drawing. --no-dxf and --no-svg skip the drawings; report.json says what was converted, refused or unsupported.

In short

  • XLSX, CSV and JSONL with entities, layers and block attributes.
  • The drawing as DXF and SVG.
  • report.json and REPORT.txt: how many records were converted, refused or of a type that is not supported yet.
  • Batch conversion of several drawings in one call, with one JSON status line per file (--json).

Worked example

Entity count per type for a whole drawing, in one line of pandas

DDC-Sample-House.dwg by DataDrivenConstruction, converted with DDC DWG to Excel 0.4.1: the Entities sheet has 8,435 rows. The 8 most frequent entity types cover 6,792 of them.

Python, pandas
import pandas as pd
df = pd.read_excel("DDC-Sample-House.xlsx", sheet_name="Entities")
df["type_name"].value_counts().head(8)

Block attributes, lines, texts and block inserts make up most of the rows; filter by layer_name or type_name to schedule what you need.

How to convert

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. Download the Setup.exe or the portable ZIP.
  2. Start the app and choose DWG files.
  3. Press Convert. A folder per drawing appears.
PowerShell, in the unzipped folder
# a folder Plan with xlsx, csv, jsonl, dxf, svg and the report
> dwg2excel.exe "C:\Drawings\Plan.dwg" -o "C:\Out"
Python, every file in a folder
import subprocess, pathlib
files = [str(f) for f in pathlib.Path(r"C:\Drawings").glob("*.dwg")]
subprocess.run(["dwg2excel.exe", *files, "-o", r"C:\Out", "--no-dxf", "--no-svg", "--json"], check=True)

Folders of files, nightly runs, checks and reports: n8n workflows that call the converters.

Supported scope

  • Some object types are reported as unsupported or refused instead of being exported; report.json lists them.
  • Output is data plus DXF and SVG drawings, not 3D geometry for BIM.
  • We do not convert DWG to IFC or RVT.
  • Windows 10/11 64-bit only.

Reviews and a walkthrough

AutoCAD DWG Processing with ChatGPT: No AutoCAD Needed. Guide for Efficient File Management. Plays from youtube-nocookie.com after you click.

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.

DataDrivenConstruction Excel Add-In is a wonderful additional tool to help extract data from CAD (BIM) Revit, IFC, DWG files in order to move forward with information validation processes in your workflows. Additionally the possibility to turn the long complex Excel file into easily human-and machine-readable files keep the Add-In modern and compatible with recent developments within IT. As we move forward in the industry it is crucial to think about diversity of data and how to find the most suitable outputs in order to keep said data valuable, up to date and usable. An influential tool with a user-friendly interface helping the construction industry move towards the future!

Questions

Questions about CAD Drawing to Excel

Short answers, including the ones that are no. Where we do not do something, we say what works instead.

All questions
Which DWG versions are supported?

Drawings from R13 to 2018. Object types that are not supported yet are reported in report.json instead of being silently dropped.

Do I need AutoCAD?

No. The converter reads DWG files without AutoCAD or an Autodesk licence.

What columns does the Excel file have?

One row per entity with its handle, class, layer, linetype, length, area and block attributes. Our sample drawing DDC-Sample-House.dwg gives 8,435 rows and 95 columns.

Which files does it write?

XLSX, CSV, JSONL, DXF and SVG plus a report, in a folder per drawing. The free <a href="https://github.com/datadrivenconstruction/cad2data-Revit-IFC-DWG/tree/main/ddc-tools">ddc-tools</a> (check, qto, table, convert) work on them.

Can it convert DWG to IFC or RVT?

No. It extracts data to tables and writes the drawing as DXF and SVG. There is no 3D BIM output.

Is this an online converter?

No. It is a download that runs on your own Windows computer. 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, including processing files for clients, needs the licence: one payment, perpetual use of the version you have, 12 months of updates, no ads. Request a quote on the licence page.
