| description | Use this skill when the user wants to create a data dashboard, analytics dashboard, KPI dashboard, or executive summary from CSV/tabular data in Excel format. Trigger on: 'dashboard', 'KPI report', 'analytics summary', 'data visualization', 'CSV to Excel dashboard', 'executive dashboard', 'metrics dashboard'. Output is always a single .xlsx file. |
Data Dashboard Skill
Create professional, formula-driven Excel dashboards from CSV or tabular data. The output is a single .xlsx file with a data sheet and a Dashboard sheet -- charts linked to live data, KPIs powered by formulas, and conditional formatting for visual insight.
BEFORE YOU START (CRITICAL)
If officecli is not installed:
macOS / Linux
if ! command -v officecli >/dev/null 2>&1; then
curl -fsSL https://raw.githubusercontent.com/iOfficeAI/OfficeCLI/main/install.sh | bash
fi
Windows (PowerShell)
if (-not (Get-Command officecli -ErrorAction SilentlyContinue)) {
irm https://raw.githubusercontent.com/iOfficeAI/OfficeCLI/main/install.ps1 | iex
}
Verify: officecli --version
If officecli is still not found after first install, open a new terminal and run the verify command again.
Use When
- User wants to create a dashboard from CSV data or tabular data
- User asks for KPI reports, analytics summaries, or metrics dashboards
- User wants to visualize data in Excel with charts, sparklines, and conditional formatting
- User mentions "CSV to Excel", "executive dashboard", or "data visualization"
What This Skill Produces
A single .xlsx file with:
| Component | Sheet | Description |
|---|
| Raw data | Sheet1 | Imported CSV with frozen headers, AutoFilter, column widths, conditional formatting |
| Dashboard | Dashboard | KPI cards (formula-driven), sparklines, charts (cell-range-linked), preset styling |
The Dashboard sheet is active on open. All formulas recalculate on open.
Core Concepts
Formula-Driven KPIs
Every KPI value on the Dashboard is a formula referencing the data sheet. Never hardcode calculated values. When the underlying data changes, KPIs update automatically.
Cell Range References for Charts
Every chart series references data sheet cells directly (series1.values="Sheet1!B2:B13"). Charts stay in sync with data. Never use inline data unless aggregation is impossible in Excel formulas.
Chart Presets
Use preset=dashboard on charts for datasets with 10+ rows. For datasets with fewer than 10 rows, use preset=minimal. See the complexity table in A.3 of creating.md for the authoritative mapping -- when any other text in this skill conflicts with that table, the table wins. Presets are DeferredAddKeys -- they work on add only, NOT on set. A single preset replaces 5-8 manual styling properties with one consistent look.
Data-Size-Aware Complexity
The number of KPIs, charts, sparklines, and CF rules scales with the input data size. A 5-row dataset gets 1 chart and no sparklines. A 200-row dataset gets 3-5 KPIs, 2-3 charts, sparklines, and multiple CF rules.
Workflow Overview
Phase 1: Analyze the Input Data
Count rows and columns. Identify column types (date, numeric, categorical). Determine the primary dimension (X-axis). Look up the data-size-to-complexity table.
Phase 2: Plan Before Building
Decide how many KPIs, which chart types, which CF rules, and chart layout positions. Write out the plan before executing any commands.
Phase 3: Build the Workbook
Follow the 11-step workflow: create + import, column widths, Dashboard sheet, KPIs, sparklines, charts, conditional formatting, tab colors, polish, raw-set, validate.
Phase 4: QA
Run the QA checklist. Fix issues. Re-validate.
Phase 5: Deliver
Deliver the .xlsx file. Tell the user the Dashboard sheet opens first and formulas recalculate automatically.

Quick Reference: Key Warnings
| Warning | Detail |
|---|
| Batch invocation | cat <<'EOF' | officecli batch dashboard.xlsx — file argument is required. officecli batch alone fails with "Required argument missing". |
| Batch JSON values | ALL values must be strings: "true" not true, "24" not 24 |
| Chart preset | Add-only. preset=dashboard for 10+ rows, preset=minimal for < 10 rows |
| Scatter charts | Use series1.xValues NOT series1.categories (causes validation error) |
| Reference lines | Format is value:color:label:dash (color BEFORE label) |
| Cell range refs | Always series1.values="Sheet1!B2:B13", never inline data |
| raw-set ordering | activeTab raw-set must be the LAST command. Use set / --prop calc.fullCalcOnLoad=true for calcPr (not raw-set). |
| formulacf | Do NOT use font.bold. Use fill + font.color only |
| Column widths | import --header does NOT auto-size. Set widths manually on ALL sheets including Dashboard |
| Dashboard ### | KPI cells at 24pt bold WILL show ### if Dashboard columns are not set to width=22. See Step 4b |
| pie chart | chartType=pie has a known rendering issue in LibreOffice — chart renders blank (only legend visible). Use chartType=doughnut or chartType=column instead for category breakdowns. |
| Dashboard KPI placement | KPI labels and values MUST be on the Dashboard sheet itself, not on Summary/Data sheets. Dashboard must show: KPI area (rows 1-2) + charts (rows 5+). See Step 3 CRITICAL box in creating.md. |
| Helper columns | After using helper columns on Dashboard for chart data sources, hide them with officecli set file.xlsx '/Dashboard/col[N]' --prop hidden=true. Visible helper columns are unprofessional clutter. |
|
Adjustments After Creation
When the user requests changes after the dashboard is built:
| Request | Command |
|---|
| Swap two sheets | officecli swap dashboard.xlsx '/Dashboard' '/Data' |
| Move a sheet after another | officecli move dashboard.xlsx '/Summary' --after '/Dashboard' |
| Edit a cell value | officecli set dashboard.xlsx '/Dashboard/A1' --prop value="..." |
| Find & replace text | officecli set dashboard.xlsx / --prop find=OldText --prop replace=NewText |
| Update chart data | officecli set dashboard.xlsx '/Dashboard/chart[N]' --prop data="A1:D10" |
