Official standards and scope
ECMA-376 defines Office Open XML, read-excel-file documents the parser used here, and the HTML Standard defines the table model. This page accepts only a filename ending in .xlsx. Although bundled read-excel-file 9.2.0 returns all sheets, the implementation uses only the first sheet and offers no sheet selection, schema, custom date format, or formula evaluation. It treats the first returned row as th cells and every later row as td cells, escapes cell text for HTML, and emits a table with thead and tbody. It does not infer whether the workbook actually has a header row, normalize ragged rows, recreate merged cells, choose row or column scopes, or add caption and accessibility context. Styles, formulas, links, comments, images, number formats, workbook metadata, and exact value presentation are not preserved. Review the first-row assumption and resulting table semantics before embedding the fragment.
