What it does
Excel Model is an agent skill from mohitagw15856/pm-claude-skills. Build a real, formula-driven Excel (.xlsx) model — not a static table. Use when asked to build an Excel model, a financial model, a budget/forecast spreadsheet, or any .xlsx with live formulas a user can edit. Produces an actual .xlsx file via a generated openpyxl script: an inputs/assumptions sheet, calculation sheets with real cell formulas, and formatting — so changing an input recalculates the model. Requires a code-execution environment (Claude Code, the API code tool, or Claude.ai).
Its SKILL.md is about 1.2k tokens, which your agent loads only when the skill is triggered. The skill folder holds 2 other files, including scripts (for example `scripts/xlsx_tool.py`).
It sits in Documents & Office, covering Excel spreadsheets. It works with Microsoft Excel and openpyxl. The repository describes itself as: 1255 professional Agent Skills for Claude, ChatGPT, Gemini, Cursor & Codex — PRDs, postmortems, leases, medical bills, layoffs, go-bags, new countries. Plain markdown, MIT, in… The licence is MIT.
When your agent uses it
- Asked to build an Excel model
- A financial model
- A budget/forecast spreadsheet
- Any .xlsx with live formulas a user can edit
Example prompts
- “/excel-model”
Requirements
- Python 3
Workflow steps
3 steps, taken from the first numbered list in SKILL.md.
- Design before coding — lay out the sheets (Inputs · Calculations · Output/Summary), and which cells are inputs vs. formulas. Confirm the…
- Write an openpyxl script that
- Run it, then state the formulas used and tell the user which cells to change to flex the model.
What it can do on your machine
Read from SKILL.md and the folder at commit 1cbf1f0. It shows what the files ask for, not the result of running them.
Tool permissions
Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.
From allowed-tools in the SKILL.md frontmatter.
Runs code
Ships 1 file in scripts/ (Python), which the agent can run.
Shell commands in SKILL.md call:
python3
From the folder's file list and the shell code blocks in SKILL.md.
Network
No URLs in SKILL.md.
From URLs in SKILL.md, links to its own repository left out.
Credentials
Names no API keys, tokens, secrets or passwords.
From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.
Context cost
Excel Model loads about 1.2k tokens when it runs. Until then it costs about 126 tokens; SKILL.md has 557 words of instructions outside code blocks.
Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.
Safety
Auto-check passed
The automated check found no risky patterns in SKILL.md.
Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); the scripts in this folder are not scanned.

- description
- Build a real, formula-driven Excel (.xlsx) model — not a static table. Use when asked to build an Excel model, a financial model, a budget/forecast spreadsheet, or any .xlsx with live formulas a user can edit. Produces an actual .xlsx file via a generated openpyxl script: an inputs/assumptions sheet, calculation sheets with real cell formulas, and formatting — so changing an input recalculates the model. Requires a code-execution environment (Claude Code, the API code tool, or Claude.ai).
Excel Model Skill
A model is only useful if it's live — change an assumption and everything recalculates. A markdown
table can't do that; a real .xlsx with cell formulas can. This skill builds an actual Excel workbook by
writing and running an openpyxl script: a clean inputs sheet, calculation sheets that reference
those inputs with real = formulas, and sensible formatting — so the user gets a file they can drive,
not a snapshot.
Environment: this produces a binary file, so it needs a place to run code — Claude Code, the Anthropic API code-execution tool, or Claude.ai (with the analysis/code tool). In the browser playground (no code execution), use the markdown output as the spec instead.
Required Inputs
Ask for these only if they aren't already provided:
- What the model is — financial model, budget, forecast, pricing model, scenario planner, etc.
- The inputs/assumptions — the driver variables (and rough values) the user will change.
- The outputs — what it should compute (revenue, burn, margins, totals, a P&L, etc.).
- Structure — periods (months/years), tiers/segments, and any required layout.
Process
- Design before coding — lay out the sheets (Inputs · Calculations · Output/Summary), and which cells are inputs vs. formulas. Confirm the calculation logic with the user if non-trivial.
- Write an
openpyxlscript that:- Puts all driver assumptions on an Inputs sheet (one source of truth), labelled and formatted.
- Builds calculation cells as real formulas referencing the input cells (e.g.
=Inputs!B2*Inputs!B3), never hard-coded results — so the model is live. - Adds formatting: headers, number/currency/percent formats, column widths, and light cell styling for readability.
- Saves to a clearly named
.xlsx.
- Run it, then state the formulas used and tell the user which cells to change to flex the model.
Output Format
- The generated
.xlsxfile (the deliverable). - A short README of the model: the sheets, the input cells to change, the key formulas in plain English, and any assumptions.
Show full SKILL.md (248 more words)Show less
Quality Checks
- Calculations are live cell formulas, not pasted static values
- All driver assumptions live on one Inputs sheet and are referenced, not duplicated
- Numbers are formatted (currency/percent/thousands) and sheets are readable
- The script runs cleanly and the file opens in Excel/Sheets/Numbers
- The user is told exactly which cells to change to drive the model
Anti-Patterns
- Do not write computed results as static numbers — the whole point is that inputs recalculate
- Do not hard-code an assumption inside a formula — put it on the Inputs sheet and reference it
- Do not scatter inputs across sheets — one assumptions sheet, single source of truth
- Do not skip formatting — an unformatted grid of numbers is hard to trust or use
- Do not claim a file was produced if there was no code execution — fall back to a clear spec instead
Based On
Financial-modelling best practice (separate inputs from calculations, formula-driven, no hard-codes) implemented with openpyxl.
Programmatic Helper
This skill ships scripts/xlsx_tool.py — a zero-dependency (stdlib zip+XML) tool that produces real .xlsx files, so the model you design can be delivered as a working workbook, not a markdown table:
# Build a workbook from JSON (numbers stay numbers, "=B2*C2" becomes a live formula)
python3 scripts/xlsx_tool.py create model.xlsx --data '{"Model": [["Item","Qty","Price","Total"],["Widget",4,9.5,"=B2*C2"]]}'
# Fill {{placeholders}} in an existing template workbook
python3 scripts/xlsx_tool.py fill template.xlsx out.xlsx --values '{"month":"July","revenue":21000}'Design the model first (per this skill), then emit the JSON and run create. Honest limits: default styling only, no charts — for formatted finals, open the generated file and style it, or use the playground's Excel export.
Example Trigger Phrases
- "Build an Excel model."
- "Build a financial model in Excel."
- "Make a budget spreadsheet with live formulas."
- "Make me an .xlsx forecast I can edit."
