I take it no one uses Spanner files to import Excel spread sheets into Acad. If you do let me know. I'm still looking for the update spaner files for Acad 12. Thanks
Since Spanner was a commercial product I don't think anyone will send you any files. Next, as far as I know the last update of Spanner might have been for 12, but that was R12 (1992) not 2012. I believe the company no longer produces the product.
