The io.Connect Excel Adapter enables apps to use Excel as a data editor.
The `@interopio/office` library provides client APIs to your interop-enabled apps which they can use to interact with Excel via the Excel Adapter.
The app uploads tabular data into Excel and the user can view it and edit by using a familiar editor.
When changes are made in Excel, they are transmitted back to the app for validation, processing, auditing, and long-term storage.
