Minitab worksheet export to Microsoft Excel: preserved semantics or data only

The goal is to decide whether Minitab's export to Microsoft Excel is an accessible reporting channel or only a raw data-exchange step. The integration boundary is between Minitab worksheets, graphs, and output panes and the resulting Excel workbook.

Minitab can import tabular data and return worksheet values to Excel, but whether that return path preserves semantics for assistive technology is unresolved. Column headers, data types, sheet names, missing-value markers, and logical reading order may survive as visible formatting yet remain unavailable to a screen reader. Graph meaning, labels, and explanatory context may not carry over at all. Results can also vary by Minitab release, operating system, and installed assistive software, so the installed release's supported-format and accessibility documentation should be reviewed before the behavior is treated as a requirement.

Does the exported workbook retain row and column headers, sheet names, and reading order announced by a screen reader? Should the accessible deliverable be the Excel workbook, a companion report, or Minitab's in-product output? Which export settings control semantic preservation rather than visible formatting only?
