In Autodesk® AutoCAD® or its vertical products, invoke the NTCL_BlockToExcel command. The user form will appear together with an Excel instance if Excel has not been opened before

1. For the Active drawing processing option,

Remember to reserve 1 blank column at the active cell (values will be written downward))

• Select macro mode: 1 (Cad Block info => Excel worksheet) or 2 (Excel info => Cad Block update). 
• Select additional options (Single worksheet, Uni Header, select block name(s), where to get block refs from, which information to export, and import). 
• Mode 1 (Export) should run before Mode 2 (Import) unless you saved and re-use the results of Mode 1 before.
• If you select mode 1, the block information will be exported to Excel.  Data are written to the active worksheet
• If you select mode 2, the block information will be imported from Excel.  Be sure to pre-select the data range in Excel first. The selected range must include a header row & a handle column. 

2. For the Multi files processing option, 

• Load the drawing list from folder/ from files/ from Excel files .... to the table.
• Select macro mode: 1 (Cad Block info => Excel worksheet) or 2 (Excel info => Cad Block update). 
• Select additional options (Single worksheet, Uni Header, select block name(s), where to get block refs from, which information to export, and import). 
• Mode 1 (Export) should run before Mode 2 (Import) unless you saved and re-use the results of Mode 1 before.
• If you select mode 1, the block information will be exported to Excel: New worksheet(s)  will be created in the active workbook.
• If you select mode 2, the block information will be imported from the Excel worksheet(s).  Be sure you have written permission for drawings in List.

Be aware that, this app CAN NOT create new block references, so the workflow is often: Export block data - Edit data in Excel - Import block data to update AutoCAD drawing.

For the Multiple Visibility States dynamic block, only Attributes that are set visible in the active visibility state are exported/ imported.

If you have multiple Excel instances already open, this App may tie to the last activated Excel instance but sometimes it does not. In such a case, please close all opening Excel instances; close (end task) any invisible Excel.exe process by Task Manager, and re-open only one Excel instance.

In such cases, please close all Excel instances, including those invisible Excel.exe processes.

2. Since version 2.1.3, App is installed to %AppData% \Autodesk\ApplicationPlugins folder  instead of  %ProgramData%\Autodesk\ApplicationPlugins folder.  The first session of Autodesk® AutoCAD® and/or verticals  after updating will have to update some registry keys due to path change, App will NOT work in this session.  Please close and re-open Autodesk® AutoCAD® and/or verticals.  App will work properly from the second session onwards.
