JTB BatchAttEdit is a new batch attribute editor app for AutoCAD from JTB World. The app collects attributes in all blocks of specified name patterns in multiple drawings and display in a wide spreadsheet. Then you can edit attribute texts as easy as working with Excel. Once done, click "Apply Attribute Changes" to update values to drawings.
This makes it a great app to for example edit title block attributes across many drawings instead of having to do it one drawing at a time.
Trial of JTB BatchAttEdit is available.
