DDC Import Excel to Revit

📋 Import Parameter Values from Excel

The DDC Import Excel add-in allows you to import parameter values from an Excel database created with the DataDrivenConstruction Excel Add-in or the DDC Revit Converter.

Revit 2020-2024

To install the add-in for Revit 20XX, run the following installer:

\DdcImportExcel\DdcImportExcel.Installer\output\DdcImportExcel--Revit20XX.msi

After installation, restart all Revit instances if any were running.

Export your Revit model to an Excel (.xlsx) file using the DataDrivenConstruction Excel Add-in or the DDC Revit Converter.
Open Revit, go to the Add-Ins tab, and select Import DDC Excel from the DdcImportExcel panel.
If an .xlsx file with the same name as your model (with a _rvt postfix) is found in the DDC subfolder of your model's directory, it will be used automatically.
If no such file is found, the add-in will prompt you to locate it.
Import will occur from a sheet named after the model name, truncated to 25 characters. If no such sheet is found, you will be prompted to enter the correct sheet name.
After the import is complete, a log file will be saved in the Windows temporary folder. You will be prompted to open it (for example, in Notepad).

If changes are not reflected in Revit, try the following:

Change the parameter name to Name and remove the : String type suffix, so only Name remains.

Change parameter values directly in Excel and import them back into the Revit model.
Create new parameters by adding new columns to the sheet and using the new_ prefix for the parameter names.
New parameters will be created as shared project parameters for the instance elements of the corresponding category.
Data types for new parameters should be defined using a colon : after the parameter name (currently, only String type is supported).
