What it does
XLSX is an agent skill from flonat/flonat-research. Create, read, edit, clean, format, chart, or convert spreadsheet files while preserving spreadsheet-native deliverables. Use when .xlsx, .xlsm, .csv, or .tsv data is the primary input or a spreadsheet is the requested output. Not for Word documents, HTML reports, standalone scripts, database pipelines, or Google Sheets API work.
Its SKILL.md is about 2.7k tokens, which your agent loads only when the skill is triggered. The skill folder holds 63 other files, including scripts (for example `scripts/office/helpers/__init__.py`, `scripts/office/helpers/merge_runs.py` and `scripts/office/helpers/simplify_redlines.py`).
It sits in Documents & Office, covering Excel spreadsheets. It works with Microsoft Excel and Google Sheets. The repository describes itself as: Shareable Claude Code + Codex infrastructure for PhD researchers — skills, agents, hooks, and rules for academic workflows.
When your agent uses it
- .tsv data is the primary input
- A spreadsheet is the requested output
Example prompts
- “/xlsx”
Requirements
- Python 3
- Pre-approved tools (allowed-tools): Bash(uv*, mkdir*, ls*), Read, Write
Workflow steps
6 steps, taken from the first numbered list in SKILL.md.
- Choose tool: pandas for data, openpyxl for formulas/formatting
- Create/Load: Create new workbook or load existing file
- Modify: Add/edit data, formulas, and formatting
- Save: Write to file
- Recalculate formulas (MANDATORY IF USING FORMULAS): Use the scripts/recalc.py script
- Verify and fix any errors
What it can do on your machine
Read from SKILL.md and the folder at commit da27600. It shows what the files ask for, not the result of running them.
Tool permissions
Pre-approves these tools, so the agent can use them without asking each time:
Bash(uv*mkdir*ls*)ReadWrite
From allowed-tools in the SKILL.md frontmatter.
Runs code
Ships 14 files in scripts/ (Python, from the files we listed), which the agent can run.
Shell commands in SKILL.md call:
uv
From the folder's file list and the shell code blocks in SKILL.md.
Network
No URLs in SKILL.md. Its commands use uv, which can reach the network depending on how they are called.
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
XLSX loads about 2.7k tokens when it runs. Until then it costs about 84 tokens; SKILL.md has 980 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
Its licence (Proprietary) doesn't allow us to republish the file, so here is its outline and opening line. It has 980 words (~2,729 tokens).

When should I use XLSX?
XLSX fits situations like: .tsv data is the primary input; A spreadsheet is the requested output.
How do I install XLSX in Claude Code?
Run `npx skills add flonat/flonat-research --skill xlsx -a claude-code`. Or copy the skill folder (skills/xlsx in flonat/flonat-research) into .claude/skills/xlsx in your project. Claude Code loads it when a task matches its description.
How do I install XLSX in Codex?
Run `npx skills add flonat/flonat-research --skill xlsx -a codex`. Or copy the skill folder (skills/xlsx in flonat/flonat-research) into .agents/skills/xlsx in your project. Codex loads it when a task matches its description.
Can I use XLSX 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 flonat/flonat-research --skill xlsx -a cursor` (or -a gemini-cli, github-copilot or opencode for the others). To copy it by hand, put the folder in .cursor/skills/xlsx, .gemini/skills/xlsx, .github/skills/xlsx and .opencode/skills/xlsx in your project.
What does XLSX need to run?
Going by SKILL.md and its folder, XLSX needs Python for the scripts in its folder and the command-line tools its instructions call (uv). Our summary lists: Python 3. Its frontmatter pre-approves these tools: Bash(uv*, mkdir*, ls*), Read, Write.
Does XLSX access the network?
SKILL.md contains no URLs. Its commands use uv, which can reach the network depending on how they are called. This is read from the text; nothing was executed.
Is XLSX 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 XLSX use?
XLSX carries a proprietary licence (declared in SKILL.md). It is published on GitHub, but it is not open source: read the licence file before using or sharing it.
How many tokens does XLSX use?
About 2.7k tokens (SKILL.md is roughly 11k characters). Agents keep only the skill's name and description in context until a task matches; then they load SKILL.md in full.
What are the alternatives to XLSX?
Skills that share tags, products or a category with XLSX: XLSX (zzhonglei/GeoCode-Release, 189 stars), Spreadsheet Agent (mastra-ai/mastra, 29k stars), Sheets Artifact (asgeirtj/system_prompts_leaks, 69k stars) and Spreadsheet Formula Helper (composio-community/awesome-codex-skills, 17k stars). The comparison table on this page puts their stars, adoption, token cost, safety result and licence side by side.
