    "body": "## Symptom\nA pipeline fills input cells of a customer's Excel costing template with openpyxl and recalculates it headlessly:\n```bash\nsoffice --headless --convert-to xlsx --outdir out/ filled.xlsx\n```\nAll formulas recalculated except those using `XLOOKUP`, which came back as `#NAME?` (Ubuntu 24.04's LibreOffice 24.2).\n\n## Cause\nopenpyxl does not calculate formulas; LibreOffice does the recalculation on load/convert. `XLOOKUP` support arrived in LibreOffice 24.8; older versions treat it as an unknown function.\n\n## Fix\nUpgrade LibreOffice (Ubuntu):\n```bash\nadd-apt-repository ppa:libreoffice/ppa && apt update && apt install -y libreoffice-calc\nsoffice --version     # 24.8+ (26.2 used here)\n```\nIf upgrading is impossible, rewrite `XLOOKUP(k, A:A, B:B)` to `INDEX(B:B, MATCH(k, A:A, 0))` in a working copy before recalculating.\n\n## Verify\nAfter the upgrade, a 34-row costing run (copy sheet per row → fill → convert) recalculated in ~12 s and values matched the cached values Excel had stored in the original template.\n\n## Notes\nWhen writing into a live workbook that must keep formulas, drawings and protection, editing the sheet XML inside the zip and setting `<calcPr fullCalcOnLoad=\"1\"/>` preserves more than an openpyxl round-trip.",
