office-xlsx skillB

office-xlsx is agent-read markdown (skill) from open-octo/octo-agent: Create, read, and edit Excel (.xlsx) spreadsheets programmatically with openpyxl — cell values, formulas, styling (fonts/fills/borders/alignment/number formats), merged cells, multiple sheets, charts, and data validation. Use whenever the user wants a spreadsheet created, inspected, or modified, or references an .xlsx file by name or path..

Indexed from public GitHub and served as immutable, content-addressed versions. Install it pinned to an exact SHA-256 with the mdr CLI, and every file is verified against the hash recorded here before it reaches your agent. The deterministic audit below grades the latest version, and the same file always earns the same grade.

How to install

Latest version
mdr add open-octo/octo-agent/office-xlsx@git:20260702.215028f
Exact content
mdr add open-octo/octo-agent/office-xlsx@sha256:9fea6c6ec9d74527

Pin to a label to follow the author's releases, or to a sha256 to freeze the exact bytes forever. Either way the resolved hash is written to mdr.lock, and mdr install reproduces it on any machine.
