AutoTableDXF: Link Excel to Revit

"AutoTableDXF is an add-in for Excel. It is designed to provide Revit / Inventor users a more convenient way working together with Excel. AutoTableDXF exports the Excel spreadsheet to a DXF file and keeps the DXF file up-to-date." The DXF file can then be linked into Revit.

Pricing starts at $79 per standalone license. There is a demo version available.
