Source notes
Why these candidatesEach candidate comes from tracked public sources and has a source-attributed adoption signal. This is a shortlist, not a catalogue or global ranking.
What this cannot establishWe read declared instructions and public signals. We do not run skills, benchmark outputs, audit security, or claim a universal best choice.
Use it forGeneral Excel business analysis that needs cleaning, KPI calculations, pivots, charts, and an Excel output.
Avoid ifYou need an explicitly audit-oriented preservation-and-verification workflow for every workbook change.
ActionInstall and use as the default spreadsheet-analysis skill.
EditsAdapt column names, metrics, and chart choices to the business question.
SetupRequires pandas; the documented examples also use openpyxl and matplotlib.
ContextReads Excel, supports multi-sheet processing, aggregation, calculated metrics, pivot tables, charts, cleaning, and Excel export.
OutputCleaned and summarized Excel workbooks plus image charts or pivot-report files.
ControlCode examples provide direct pandas/openpyxl workflows.
InvocationNot yet mapped from the source.
Install scopeNot yet mapped from the source.
Agent fitStrong default fit across the task's cleaning, formulas/KPIs, pivot, chart, and reviewable-output needs.
Watch outThe documented charts are saved as image files; review the resulting workbooks and calculations before relying on them.

Use it forBusiness-facing Excel analysis where the main deliverable is an insight-led interactive report, presentation, or concise management summary.
Avoid ifYou only need a narrowly scoped workbook operation with a short, deterministic spreadsheet workflow.
ActionInstall and use for analysis-to-report workflows.
EditsSpecify the audience, business question, and desired report format before analysis.
SetupExcel analysis is documented as using pandas and openpyxl; presentation work additionally lists Node.js packages.
ContextCovers Excel analysis, ROI review, visualization, reporting, formula generation, and presentation work, with an insight-first reporting structure.
OutputInteractive HTML report by default; Markdown for quick exploration and HTML-to-PPTX when explicitly requested.
ControlClarifies ambiguous fields, analysis dimensions, audience, and business judgments before proceeding.
InvocationNot yet mapped from the source.
Install scopeNot yet mapped from the source.
Agent fitBest when transparent data-backed conclusions and polished stakeholder communication matter as much as the spreadsheet analysis.
Watch outThe default output is an HTML report rather than a workbook; choose it when that delivery format fits the review process.

Use it forAuditable XLSX, CSV, or TSV analysis and workbook delivery where preserving source files and verifying the final workbook are essential.
Avoid ifYou want a prescribed business-insight report or a deeply specialized large-file workflow.
ActionInstall and use for controlled spreadsheet transformations and reviewable workbook outputs.
EditsAdapt the analysis logic and KPI definitions to the dataset; retain the prescribed output verification.
SetupUses Python csv or pandas for analysis and openpyxl for workbook features; LibreOffice is conditional for conversion or recalculation.
ContextHandles spreadsheet cleaning, analysis, formulas, charts, reports, formatting, and conversion, with explicit safeguards for source preservation and auditability.
OutputA new output workbook or tabular report, normally keeping raw data separate from summaries.
ControlClassifies the task first, selects tools by operation, and verifies workbook structure and representative values.
InvocationNot yet mapped from the source.
Install scopeNot yet mapped from the source.
Agent fitA strong practical alternative when transparent calculations, source preservation, and workbook QA outweigh broad reporting features.
Watch outThe source gives a concise operational workflow rather than detailed KPI or pivot-analysis recipes.
