1. Start by opening a Microsoft® Excel® worksheet, remember to reserve 1 blank column at the active cell (values will be written downward).
2. Press Alt+Tab to return to Autodesk® AutoCAD® or its vertical products, invoke the NTCL_BlockToExcel command. The user form will appear.
3. On the user form, select your existing block by block name.
4. Select macro mode: 1 (Cad Block info => Excel worksheet) or 2 (Excel info => Cad Block update). Select additional options (where to get block refs from, which information to export, import). Mode 1 should run before Mode 2 unless you saved and re-use the results of Mode 1 before.
5. If you select mode 1, the block information will be exported to Excel. For the first export action, blank columns will be automatically added to the right side of the active cell
6. 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.
7. Be aware that, this app CANNOT create new block references, so the workflow is often: Export block data - Edit data in Excel - Import block data to update AutoCAD drawing.
8. 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 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.

1. Be aware that unsaved values that are overwritten in the Excel worksheet by this app cannot be undone in Excel. It is recommended to save an Excel worksheet & reserve enough blank columns/ or check the "Auto insert blank columns before exporting" before running this app.
2. If no results are returned to Excel, please check: (a) Input values are correct, sometimes a block is defined but no block reference placed in drawing (b) App is being tied to an invisible running Excel.exe process. In such cases, please close all Excel instances, including those invisible Excel.exe process.
3. If no Excel worksheet is opened before, this app will try to open a blank worksheet.
