I wrote about a script I had written to copy values from an excel (or open office) spreadsheet to a Revit Schedule. I have updated the script and the prep work needed to run the script have been minimized drastically. The script also allows you to select the cell in Excel / Revit to start copying / pasting. The updated script, the script code, and the readme file are here for Revit 2009 and here for Revit 2010.
I also wrote about another script that can copy values from one Revit schedule to another. This script has also been enhanced to need minimal prep work. The updated script to copy a revit schedule, the code, and the readme file are here for Revit 2009.
Please add a comment if you find any bugs or if you have any requests. Thanks.
