Create or edit spreadsheets (.xlsx/.xlsm/.csv) with formulas, formatting and charts, or clean messy tabular data into one.
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
# XLSX creation, editing, and analysis | Task | Approach | |---|---| | **Create** a workbook with formulas | Copy `scripts/example_model.py`, replace its inputs and columns, run it — see below | | **Edit** with formulas/formatting | `openpyxl` — see gotchas below | | **Bulk data** in or out | `pandas` (`read_excel`, `to_excel`) | | **Quick look** at a sheet | `read_file(path="file.xlsx")` — the harness parses it natively, `## SheetName` per sheet with cached values; `.csv`/`.tsv` are plain text it reads too. No cell coordinates, so don't plan edits from it | | **Read** cells: formula *and* value, with coordinates | `python scripts/show.py file.xlsx [Sheet] [A1:H20]` — don't write your own dump script | > `openpyxl` and `pandas` are preinstalled — do not run `pip install` first; write the script and import directly. Only if an import fails: `pip install` the missing package. The sandbox runs as a non-root user without `sudo`, so `apt-get install` always fails. > Script paths below are relative to this skill's directory — the `staged_at` path `skill_view` returns. ## Creating a workbook …

How to install
mdr add invergent-ai/surogates/xlsx@sha256:ee4a5b34fcba9f0cThe line at the top of this page pins the label git:20261104.c3eaa01, 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.
