The most reliable merge is the one nobody has to remember to run. When fresh data lands every Monday, opening an app and clicking through a merge is a manual step waiting to be forgotten.
DataMergeStudio speaks AppleScript, the Mac’s common automation language. Scripts can load a project, import a new datasource, and start a merge – the complete core of a run, without anyone touching the app.
Wrap those steps in whatever already runs your Mac: a folder action that fires when the weekly export lands, a scheduler, an Automator or Shortcuts workflow, another app’s pipeline. New data arrives, the script points the existing project at it, the output appears. The merge becomes infrastructure – set up once, running on its own.
