ETL: Extract Revit Model Data to Structured Excel

This n8n workflow transforms Revit (.rvt) files into structured Excel data and parses them into individual items ready for downstream processing. It executes a local Windows executable (RvtExporter.exe from DDC Revit toolkit) to convert the model, checks for success, derives the output Excel filename, reads the file from disk, and converts rows into n8n data items.

Key benefits include automating tedious manual exports from Revit, enabling seamless integration into ETL pipelines for analysis, reporting, or database loading. It's ideal for architects, engineers, and BIM managers handling large models, saving hours of repetitive work and reducing errors from manual data handling.

Use cases: Batch processing project models for quantity takeoffs, compliance reporting, or feeding data into BI tools like Power BI. Prerequisites include a Windows host with the DDC toolkit installed and read/write access to Revit files. Customize paths in the setup node and run via manual trigger for instant results.

On success, it outputs parsed rows as n8n items and creates an Excel file next to the original .rvt. Notes: Update filename logic if output paths vary; avoid non-ASCII paths for reliability.
