What it does

Spreadsheet Ops is an agent skill from aipoch/medical-research-skills. Spreadsheet processing and analysis for CSV/Excel; trigger when users ask to merge/clean tabular data, run statistics, add/edit Excel formulas, apply formatting, generate charts, or force workbook recalculation.

Its SKILL.md is about 1.7k tokens, which your agent loads only when the skill is triggered. The skill folder holds 19 other files, including scripts and reference files (for example `POLISH_CHANGELOG.md`, `eval_report_spreadsheet-ops_result.json` and `references/analysis.md`).

It sits in Documents & Office, covering Excel spreadsheets. It works with Microsoft Excel and Python. The repository describes itself as: Hundreds of agent skills for medical research, including protocol design, data analysis, evidence insights, and academic writing. The licence is MIT.

When your agent uses it

  • Users ask to merge/clean tabular data
  • Add/edit Excel formulas
  • Apply formatting
  • Generate charts

Example prompts

  • “/spreadsheet-ops”

Requirements

  • Python 3

Workflow steps

6 steps, taken from the step headings in SKILL.md.

  1. Merge files (CSV/Excel)
  2. Analyze data (CSV/Excel)
  3. Apply formulas (Excel only)
  4. Apply formatting (Excel only)
  5. Build charts (Excel only)
  6. Force workbook recalculation (Excel only)

What it can do on your machine

Read from SKILL.md and the folder at commit 686e09d. 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 6 files in scripts/ (Python), 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

Spreadsheet Ops loads about 1.7k tokens when it runs, and up to ~3k if it reads all its reference files. Until then it costs about 57 tokens; SKILL.md has 757 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~57
When it runs · the whole SKILL.md, loaded when a task matches
~1.7k
With references · SKILL.md plus every file in references/, read only if the agent opens them
~3k

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.

When to Use

  • You need to merge multiple CSV/Excel files into a single dataset and align columns.
  • You need to clean tabular data (normalize headers, deduplicate rows, resolve conflicts) before downstream use.
  • You need to perform data analysis/statistics on CSV/Excel (summaries, distributions, group-by metrics).
  • You need to add or edit formulas in an Excel workbook (including applying formulas across ranges).
  • You need to apply Excel formatting (including conditional formatting), generate charts, or force formula recalculation.

Key Features

  • CSV/Excel merge & cleaning: combine files, normalize column names, deduplicate, and resolve conflicts.
  • CSV/Excel analysis: compute descriptive statistics and analysis reports.
  • Excel-only formula operations: create/edit formulas and apply them to specified ranges.
  • Excel-only formatting: apply cell styles and conditional formatting rules.
  • Excel-only visualization: build charts from worksheet ranges.
  • Excel-only recalculation: set workbook to full recalculation (recalc flag) to ensure formulas update.

Dependencies

  • Python 3.x
  • Project Python dependencies are defined by the repository environment (e.g., requirements.txt / lockfile if present).
    (No explicit versions were provided in the source document.)

Example Usage

The following commands assume you are in the repository root and have a Python environment available.

1) Merge files (CSV/Excel)
bash
python scripts/merge_files.py
2) Analyze data (CSV/Excel)
bash
python scripts/analyze_data.py
3) Apply formulas (Excel only)
bash
python scripts/apply_formulas.py
4) Apply formatting (Excel only)
bash
python scripts/apply_formatting.py
5) Build charts (Excel only)
bash
python scripts/build_charts.py
6) Force workbook recalculation (Excel only)
bash
python scripts/recalc_workbook.py

Implementation Details

  • Workflow

    1. Confirm inputs/outputs: file paths, file formats (CSV vs Excel), worksheet names, and target ranges.
    2. Choose the task type: merge, analysis, formula, formatting, chart, or recalculation.
    3. Run the corresponding script and configure parameters in CONFIG (as used by the scripts).
    4. Produce output files and any generated reports.
  • Task boundaries

    • CSV/Excel supported: merging/cleaning, data analysis.
    • Excel only: formula creation/editing, formatting, chart visualization, and recalculation.
  • Key parameters to clarify (priority)

    • Input type: CSV or Excel; single file or multiple files.
    • Worksheet names and cell ranges to operate on (Excel).
    • Whether formulas/formatting/charts must preserve original styles.
    • Desired output format: CSV / Excel / JSON / Parquet.
  • Standards / constraints

    • Python file I/O must explicitly specify encoding='utf-8'.
    • json.dump(...) must set ensure_ascii=False.
  • Reference documentation (optional)

    • Column name matching & normalization: references/column-matching.md
    • Deduplication & conflict resolution: references/dedup-conflict.md
    • Large files & performance: references/large-files.md
    • Formula design & ranges: references/formulas.md
    • Formatting & conditional formatting: references/formatting.md
    • Data analysis & statistics: references/analysis.md
    • Charts & visualization: references/visualization.md
    • Formula recalculation: references/recalc.md

When Not to Use

  • Do not proceed when required input files, identifiers, parameters, or context are missing — ask the user to provide them first.
  • Do not assume capabilities beyond this skill's declared scope when the user requests external operations or inferences.
  • Do not proceed without user confirmation when overwriting existing results, executing high-cost batch operations, or expanding task scope.

Required Inputs

FieldRequiredFormat/SourceExampleIf Missing
User task descriptionYesTextResearch question, writing goal, analysis objectiveStop and ask user to provide
Primary input materialDepends on taskText, file path, ID, table, or literaturePMID, PDF, CSV, DOCX, keywords, etc.Specify which material type is missing
Output preferenceNoTextLanguage, format, target journal, templateUse skill default format

Output Contract

  • Primary output: Structured result or target file aligned with this skill's objective.
  • Optional output: Intermediate check notes, issue list, supplementary suggestions, or generated file paths.
  • Format requirement: Unless the user specifies otherwise, prefer stable, reviewable Markdown or JSON; if the skill's bundled script requires a fixed format, use that format.
  • If partially complete: Must explicitly mark as PARTIAL and state which steps are completed and which remain.

Failure Handling

  • Missing critical input: Explicitly state which fields, files, or identifiers are missing and pause.
  • Script, template, or resource execution failure: Report the failing step, likely cause, and recovery suggestions — do not silently degrade.
  • Partial completion only: Return the verified portion first, then list remaining blockers and suggested next steps.

User Checkpoints

  • Before executing batch processing, overwriting files, long-running searches, or multi-stage generation, confirm scope and output format with the user.
  • Before proceeding when a key judgment is ambiguous, evidence is insufficient, or the workflow is entering the next stage, confirm with the user.

Input Validation

This skill accepts requests that match the documented purpose of spreadsheet-ops and include enough context to complete the workflow safely.

Do not continue the workflow when the request is out of scope, missing a critical input, or would require unsupported assumptions. Instead respond:

spreadsheet-ops only handles its documented workflow. Please provide the missing required inputs or switch to a more suitable skill.

Quick Validation

  • Check that key scripts, templates, or reference file paths this skill depends on exist.
  • Check that the final output contains the core fields, sections, or files specified for this task.
  • Check that results clearly mark assumptions, limitations, and incomplete items.
