About HTML and XLSX

HTML (HyperText Markup Language) is the markup language web pages are built from — structured text with links, images, and styling defined by tags.

XLSX (Microsoft Excel Workbook (Office Open XML)) is Excel's modern XML-based format, supporting formulas, multiple sheets, charts, and conditional formatting.

What to expect: HTML carries little to no formatting of its own, so the XLSX output will start plain — you can add styling afterward in a compatible editor.
