What it does
Excel is an agent skill from IgorWarzocha/Opencode-Workflows. Handle spreadsheet operations (Excel/CSV) with high-fidelity modeling, financial analysis, and visual verification. Use for budget models, data dashboards, and complex formula-heavy sheets. Use proactively when zero formula errors and professional standards are required. Examples: - user: "Build an LBO model" - create Excel with banking-standard formatting - user: "Analyze this data and create a dashboard" - use openpyxl + artifacttool - user: "Verify formulas in this spreadsheet" - run recalc.py to check for…
Its SKILL.md is about 540 tokens, which your agent loads only when the skill is triggered. The skill folder holds 29 other files, including scripts and reference files (for example `references/artifact_tool_spreadsheet_formulas.md`, `references/artifact_tool_spreadsheets_api.md` and `references/examples/create_basic_spreadsheet.py`).
It sits in Documents & Office, covering Excel spreadsheets. It works with Microsoft Excel and openpyxl. The repository describes itself as: An ever evolving repository of Opencode workflow examples that might enhance your experience with it. I only left the stuff that actually works. YMMV.
When your agent uses it
- Data dashboards
- Complex formula-heavy sheets
Example prompts
- “Build an LBO model”
- “Analyze this data and create a dashboard”
- “Verify formulas in this spreadsheet”
- “/excel”
Requirements
- Python 3
Workflow steps
2 steps, taken from the step headings in SKILL.md.
- Data Analysis (Pandas)
- Verification Loop (MANDATORY)
What it can do on your machine
Read from SKILL.md and the folder at commit 6444ec4. 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, from the files we listed), which the agent can run.
Shell commands in SKILL.md call:
python
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 loads about 536 tokens when it runs, and up to ~46k if it reads all its reference files. Until then it costs about 133 tokens; SKILL.md has 179 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.
SKILL.md
Without a licence we can't republish the file, so here is its outline and opening line. It has 179 words (~536 tokens).
“Before delivery, you MUST run the audit script:”

When should I use Excel?
Excel fits situations like: data dashboards; complex formula-heavy sheets.
How do I install Excel in Claude Code?
Run `npx skills add IgorWarzocha/Opencode-Workflows --skill excel -a claude-code`. Or copy the skill folder (cowork/.opencode/skill/excel in IgorWarzocha/Opencode-Workflows) into .claude/skills/excel in your project. Claude Code loads it when a task matches its description.
How do I install Excel in Codex?
Run `npx skills add IgorWarzocha/Opencode-Workflows --skill excel -a codex`. Or copy the skill folder (cowork/.opencode/skill/excel in IgorWarzocha/Opencode-Workflows) into .agents/skills/excel in your project. Codex loads it when a task matches its description.
Can I use Excel in Cursor, Gemini CLI or GitHub Copilot?
Cursor, Gemini CLI, GitHub Copilot and OpenCode also load SKILL.md folders. With the skills CLI, run `npx skills add IgorWarzocha/Opencode-Workflows --skill excel -a cursor` (or -a gemini-cli, github-copilot or opencode for the others). To copy it by hand, put the folder in .cursor/skills/excel, .gemini/skills/excel, .github/skills/excel and .opencode/skills/excel in your project.
What does Excel need to run?
Going by SKILL.md and its folder, Excel needs Python for the scripts in its folder and the command-line tools its instructions call (python). Our summary lists: Python 3.
Does Excel access the network?
SKILL.md contains no URLs. Any network use would come from the scripts or tools the agent runs. This is read from the text; nothing was executed.
Is Excel safe to install?
Our automated static check of SKILL.md found no risky patterns, such as piping downloads into a shell, reading credential files or hidden Unicode. It is not a guarantee. The check reads SKILL.md only: the scripts in the folder are not scanned, so read them before running anything.
What licence does Excel use?
No licence was found for Excel or its repository. Without one, default copyright applies: ask the author before reusing or redistributing it.
How many tokens does Excel use?
About 536 tokens (SKILL.md is roughly 2.1k characters). Agents keep only the skill's name and description in context until a task matches; then they load SKILL.md in full. Its references folder adds about 45k tokens, read only when the agent opens those files.
What are the alternatives to Excel?
Skills that share tags, products or a category with Excel: XLSX (NousResearch/hermes-agent, 252k stars), Z Md Excel (tjxj/z-skills, 546 stars), Sn Da Large File Analysis (MichaelYang-lyx/AIDABench, 111 stars) and XLSX (prapaa-ai/agav, 147 stars). The comparison table on this page puts their stars, adoption, token cost, safety result and licence side by side.
Who maintains Excel?
IgorWarzocha (a GitHub user) maintains it in IgorWarzocha/Opencode-Workflows, which has 122 GitHub stars. The repository holds 35 skills in this directory. The repository was last updated on February 4, 2026.
