Excel2DWG allows you to place Excel spreadsheets into CAD and Design applications. It runs completely inside Microsoft Excel, directly creating a DWG or DXF file as its result. You simply select your area of interest and click an icon to create the DWG file. When changes are made in Excel, the DWG files are updated when the spreadsheet closes. That means the next time the CAD project opens, the referenced spreadsheet drawing reflects these changes.
