Found by the #656 QA pass (v0.6.247, both dogfoods).

Matrix row: §3 Details pane — "Hero: PDF and office | Select PDF, docx, xlsx | First page rendered (pdf.js / converter), Open badge, click opens editor/raw". Also relevant to §7 "Converter previews".

Steps

files.c0rdyceps.ch, _qa: create qa-sheet.xlsx from New → Excel, type a few cells in Collabora, and save.
Select the file. The pane hero shows only the generic type icon, with no first page.
GET /api/v1/preview/formats → {"formats":["doc","ppt","odt","odp","rtf","docx","pptx"]} on both files (Gotenberg) and files-bao (Collabora convert-to).

Expected: the xlsx first page is rendered, as for docx and pptx.
Seen: an icon box only. Spreadsheets (xlsx, xls, ods, and probably csv) are absent from the formats list in both converter dialects, so the hero never asks for a render. Both LibreOffice-backed converters can produce a PDF from spreadsheets, so this looks like a list omission, not a converter limit. (One caveat: a spreadsheet's "first page" may be a poor thumbnail when the print area is large. If the omission is deliberate, the matrix row should say so.)

The docx hero on the same host renders through /api/v1/preview/pdf (PASS).
