A company that publishes free, finished Revit plugins - SheetLink, ParaManager, DiRootsOne and others - for bulk parameter editing, Excel round-tripping and data extraction. DiRoots tools are ready to install and use, in contrast to pyRevit, which is a platform for writing your own scripts. SheetLink handles two-way sync of Revit parameter data with Excel, ParaManager manages shared parameters in bulk, and DiRootsOne bundles several of them together. They cover the same "get data in and out of the model fast" need that a team would otherwise have to script by hand.
