DataMergeStudio is scriptable with AppleScript, so you can drive it from scripts and other Mac tools.
AppleScript support currently covers the core of a run:
That’s enough to automate the common case – point an existing project at fresh data and produce the output – without anyone opening the app by hand.
AppleScript is the Mac’s common automation language, so these steps can be wrapped in a scheduler, a folder action, or another app’s workflow: new data lands, a script loads the project, imports the datasource, and runs the merge.
That’s automation. Next comes your account: plans, seats, and AI access.
