Read, write, and generate Excel files with correct types, dates, formulas, and cross-platform compatibility.
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
## Setup On first use, read `setup.md` for integration guidelines. Ask user preferences naturally during conversation. ## When to Use User needs to read, write, or generate Excel files (.xlsx, .xls, .xlsm). Agent handles type coercion, date serialization, formula evaluation, and cross-platform quirks. ## Architecture Memory lives in `~/excel-xlsx/`. See `memory-template.md` for structure. ``` ~/excel-xlsx/ └── memory.md # Preferences, tools, pain points ``` ## Quick Reference | Topic | File | |-------|------| | Setup | `setup.md` | | Memory template | `memory-template.md` | ## Core Rules ### 1. Dates Are Serial Numbers Excel stores dates as days since 1900-01-01 (Windows) or 1904-01-01 (Mac legacy). Check workbook date system before converting. Time is fractional: 0.5 = noon, 0.25 = 6 AM. ### 2. The 1900 Leap Year Bug Excel incorrectly treats 1900 as a leap year. Serial 60 represents Feb 29, 1900 (invalid date). Account for this when calculating dates before March 1, 1900. ### 3. 15-Digit Precision Limit Numbers beyond 15 digits silently truncate. Use TEXT format for: phone numbers, IDs, credit cards, any long numeric identifiers. Leading zeros also require TEXT. …

How to install
mdr add pr-e/openclaw-master-skills/Excel / XLSX@sha256:dec4c061513d7b21The line at the top of this page pins the label v1.0.1, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
