What it does
XLSX is an agent skill from MemTensor/memmy-agent. Create, inspect, edit, recalculate, validate, render, and deliver Excel workbooks while preserving formulas, formatting, drawings, links, macros, and metadata.
Its SKILL.md is about 590 tokens, which your agent loads only when the skill is triggered. The skill folder holds 15 other files, including scripts and reference files (for example `references/formula-recalculation.md`, `references/layout-and-preservation.md` and `references/workbook-workflow.md`).
It sits in Documents & Office, covering Excel spreadsheets. It works with Microsoft Excel and OpenAI. The repository describes itself as: 🍙 A personal AI agent & local memory hub for all AI agents, gives every AI one shared, fully controlled memory and persistent context — all AI remember the same you. Now… The licence is MIT.
When your agent uses it
- Tasks that involve Excel spreadsheets
Example prompts
- “/xlsx”
Requirements
- Node.js
Workflow steps
5 steps, taken from the first numbered list in SKILL.md.
- Copy an existing workbook to a unique temporary directory and inspect it
- Preserve formulas, cached values, styles, merges, tables, filters,
- After adding or changing formulas run
- Run scripts/check_workbook.mjs --json; use --allow-lossy only
- Render with scripts/render_with_office.mjs --output-dir and
What it can do on your machine
Read from SKILL.md and the folder at commit ee0ed02. 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 9 files in scripts/ (JavaScript), which the agent can run.
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
XLSX loads about 586 tokens when it runs, and up to ~1.2k if it reads all its reference files. Until then it costs about 41 tokens; SKILL.md has 277 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.

Workbook workflow
Trigger for .xlsx, .xlsm, .xltx, .csv, and .tsv workbooks or requests
to create, read, edit, clean, format, calculate, chart, or convert them. Do
not use it for ordinary documents, web pages, databases, or live external
spreadsheet APIs.
- Copy an existing workbook to a unique temporary directory and inspect it
with
scripts/inspect_workbook.mjs --input <file> --jsonbefore editing. - Preserve formulas, cached values, styles, merges, tables, filters, validations, conditional formatting, charts, images, shapes, comments, hidden sheets, links, macros, and metadata. Only modify the requested cells or objects.
- After adding or changing formulas run
scripts/recalculate_workbook.mjs --input <file> --output <file> --json. A completed recalculation with formula errors is reported aserrors_found; a conversion or process failure is a separate failure. - Run
scripts/check_workbook.mjs <file> --json; use--allow-lossyonly when the caller explicitly accepts the listed loss. The checker does not use PPTX or XSD data. - Render with
scripts/render_with_office.mjs <file> --output-dir <dir>and inspect every sheet/page. Reopen the output and verify formulas, cached values, objects, and that the original hash is unchanged.
CSV/TSV input requires an explicit encoding, BOM, delimiter, quote, newline, and malformed-row policy. Never replace formulas with constants unless a static export was requested. External links, macros, unsupported extensions, and objects that cannot be safely preserved fail closed.
All commands are standalone Node CLIs. They write stable JSON with --json,
diagnostics to stderr, and non-zero status for invalid input, missing Office,
timeout, or unsafe preservation. The bundled renderer is resolved through
MEMMY_OFFICE_RENDERING_ROOT, the legacy DOCX override during migration, the
packaged Office payload, and the source payload; it never silently falls back
to a system PATH installation.
See references/workbook-workflow.md, references/formula-recalculation.md,
and references/layout-and-preservation.md for the full SOP.

When should I use XLSX?
XLSX fits situations like: tasks that involve Excel spreadsheets.
How do I install XLSX in Claude Code?
Run `npx skills add MemTensor/memmy-agent --skill xlsx -a claude-code`. Or copy the skill folder (App/memmy-agent/src/skills/xlsx in MemTensor/memmy-agent) 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 MemTensor/memmy-agent --skill xlsx -a codex`. Or copy the skill folder (App/memmy-agent/src/skills/xlsx in MemTensor/memmy-agent) 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 MemTensor/memmy-agent --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 JavaScript for the scripts in its folder. Our summary lists: Node.js.
Does XLSX 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 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 is published under the MIT licence (the repository's licence). It allows redistribution, so the full SKILL.md is shown on this page.
How many tokens does XLSX use?
About 586 tokens (SKILL.md is roughly 2.3k 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 565 tokens, read only when the agent opens those files.
What are the alternatives to XLSX?
Skills that share tags, products or a category with XLSX: Excel Workbook (adongwanai/learn-workbuddy, 407 stars), Markitdown (aipoch/medical-research-skills, 2k stars), Openai Spreadsheet (trailofbits/skills-curated, 512 stars) and XLSX Processing Openai (lawve-ai/awesome-legal-skills, 836 stars). The comparison table on this page puts their stars, adoption, token cost, safety result and licence side by side.
