- description
- Use this skill any time a .xlsx file is involved -- as input, output, or both. This includes: creating spreadsheets, financial models, dashboards, or trackers; reading, parsing, or extracting data from any .xlsx file; editing, modifying, or updating existing workbooks; working with formulas, charts, pivot tables, or templates; importing CSV/TSV data into Excel format. Trigger whenever the user mentions 'spreadsheet', 'workbook', 'Excel', 'financial model', 'tracker', 'dashboard', or references a .xlsx/.csv filename.
# OfficeCLI XLSX Skill
## Setup
If `officecli` is missing:
- **macOS / Linux**: `curl -fsSL https://d.officecli.ai/install.sh | bash`
- **Windows (PowerShell)**: `irm https://d.officecli.ai/install.ps1 | iex`
Verify with `officecli --version` (open a new terminal if PATH hasn't picked up). If install fails, download a binary from https://github.com/iOfficeAI/OfficeCLI/releases.
## ⚠️ Help-First Rule
**This skill teaches what good xlsx looks like, not every command flag. When a property name, enum value, or alias is uncertain, consult help BEFORE guessing.**
```bash
officecli help xlsx # List all xlsx elements
officecli help xlsx <element> # Full element schema (e.g. pivottable, chart, cf)
officecli help xlsx <verb> <element> # Verb-scoped (e.g. add chart, set cell)
officecli help xlsx <element> --json # Machine-readable schema
```
Help reflects the installed CLI version. When this skill and help disagree, **help is authoritative**.
## Shell & Execution Discipline
**Shell quoting (zsh / bash).** Excel paths contain `[]`, and number formats contain `$`. Both are shell metacharacters. Rules:
- ALWAYS quote element paths: `"/Sheet1/row[1]"`, not `/Sheet1/row[1]`.
- Use **single quotes** for any prop value containing `$`: `numFmt='$#,##0'`.
- For formulas with cross-sheet `!` references, use `batch` with a `<<'EOF'` heredoc (see Known Issues).
- `\n` and `\t` in a prop value ARE interpreted by the CLI — `\n` is a real in-cell line break (pair with `--prop wrapText=true`), `\t` a tab — consistent across xlsx / docx / pptx. Double them (`\\n`) for a literal backslash-n (rarely wanted). (`$` is the shell layer above — single-quote it.)
**Incremental execution.** Run commands one at a time and read each exit code. `officecli` mutates the file on every call; a 50-command script that fails at command 3 will cascade silently. One command → check output → continue.
## Requirements for Outputs
Before reaching for a command, know what a good xlsx looks like. These are the deliverable standards every workbook MUST meet.
### All Excel files
**Zero formula errors.** Every delivered workbook MUST have ZERO `#REF!`, `#DIV/0!`, `#VALUE!`, `#NAME?`, `#N/A`. No exceptions — guard denominators with `IFERROR` or `IF(x=0,...)`.
**Formulas, not hardcoded values.** If a number can be computed from other cells, it is a formula. Hardcoding `5000` where `=SUM(B2:B9)` belongs breaks the contract that the workbook stays live when inputs change. This is the single most important rule in this skill.
**Professional font.** Use one consistent, professional font across the workbook (Arial / Calibri / Times New Roman). Don't mix four fonts because one sheet came from CSV.
**Explicit widths.** There is no auto-fit. Any column the user will read MUST have `width` set — default 8.43 chars clips everything. Sensible starts: labels 20-25, numbers 12-15, dates 12, short codes 8-10.
**Preserve existing templates.** When editing a file that already has a look, match it. Existing conventions override these guidelines.
### Visual delivery floor (applies to EVERY workbook)
Before you declare done, run `officecli view "$FILE" html` and Read the returned HTML path to confirm all of these:
- **No `###` in any cell.** `###` means a column is too narrow for its widest value. Every column the user reads needs an explicit `width`. `###` in a delivered file is unfinished work, never "a small visual nit".
- **No truncated titles.** Sheet titles, section headers, long labels must fit. Widen the column or apply `wrapText=true` on the cell.
- **No placeholder tokens rendered as data.** `$fy$24`, `{var}`, `<TODO>`, `xxxx` must never appear in a cell, chart title, series name, or legend. These are build-time tokens that escaped replacement.
- **Pie / doughnut slices have distinct fill colors.** If the slices render same-colored, switch to `bar` / `column` or set `colors=...` explicitly.
- **No empty trailing pages / empty chart anchors.** `anchor=D2:J18` over empty source cells looks like a broken chart.
If any of the above fails, STOP and fix before declaring done.
**Print layout.** Any sheet the user may print or send as a board pack needs page setup. Default portrait + no fit-to-page splits wide tables and charts mid-way. Pick the fit mode by sheet shape:
```bash
# Summary / chart / dashboard sheet (small, ≤ ~40 rows): fit to a single page.
officecli set "$FILE" "/Summary" --prop orientation=landscape --prop fitToPage=true
# Tall data table (dozens+ rows): fit WIDTH only, let height paginate naturally.
# fitToPage=true here crushes every row onto one page → unreadable (### dates, 5px rows).
officecli set "$FILE" "/Data" --prop orientation=landscape --prop fitToPage=1x0
```
`fitToPage=true` == `1x1` == fit both axes to one page — correct only when the sheet is already short. `1x0` = fit 1 page wide, unlimited pages tall. Trigger: sheet holds a chart, or > 8 columns, or the user's ask mentions print / board / investor.
### Financial models only — skip this section if you are building a template, tracker, CSV import, or operational sheet
Scope: budgets, forecasts, 3-statement models, valuation, any `$`-heavy analytical workbook. A customer-support tracker or onboarding template does not need this section.
**Color coding — industry standard.** Five core colors used as a language, not decoration. A reviewer should tell what a cell IS by color alone — before reading the formula.
| Color | Role | Example |
|---|---|---|
| Blue text `0000FF` | Hardcoded inputs, scenario variables | `font.color=0000FF` |
| Black text `000000` | ALL formulas and calculations | default |
| Green text `008000` | Cross-sheet links inside this workbook | `font.color=008000` |
| Red text `FF0000` | Links to external files / workbooks | `font.color=FF0000` |
| Yellow fill `FFFF00` | Key assumptions needing review | `fill=FFFF00` |
A reviewer should tell what a cell IS just by its color — before reading the formula. This is a communication contract, not a cosmetic preference.
**Number formatting — standards, not preferences.**
- **Years** are text, not numbers. Format `2026` not `2,026` — use `numFmt="@"` or set `type=string`.
- **Currency** carries its unit in the header (`Revenue ($mm)`), not in every cell.
- **Zeros display as `-`**, not `0`. Use `$#,##0;($#,##0);"-"`.
- **Percentages** default to one decimal: `0.0%`.
- **Negatives use parentheses**: `(1,234)` not `-1,234`.
- **Valuation multiples** use `0.0x` format (EV/EBITDA, P/E, etc.).
**Assumptions live in cells, not inside formulas.** `=B5*(1+$B$6)` is correct; `=B5*1.05` is a bug. Document each blue hardcoded input with an adjacent source note in the next cell or a cell comment:
```
Source: Company 10-K, FY2024, Page 45, Revenue Note
Source: Bloomberg, 2026-05-02, AAPL US Equity
Source: Management guidance, Q2 2026 earnings call
```
Any hardcoded number without a source is an undocumented assumption — a reviewer cannot audit it.
## Common Workflow
Six steps. Every non-trivial build follows this shape.
1. **Open/save lifecycle.** Use `officecli open <file>` at the start and `officecli save <file>` at the end to flush to disk — `save` only writes and leaves the resident warm for follow-up edits; reach for `officecli close <file>` only to release the resident on a one-shot handoff. Both are always safe (never error or lose work). For many cells, use `batch`: **≤ 50 ops/block recommended; tested up to 80+ ops per block on pure value-set payloads with zero failures. Cross-sheet formula batches are the exception — run those non-resident, single heredoc (see Known Issues)**. **Flush only at the non-officecli boundary:** officecli's own reads always see your edits; run `save`/`close` only before a non-officecli program reads the file (openpyxl/pandas, Excel, a renderer, delivery).
2. **Create or load.** `officecli create "$FILE"` (new) or `officecli view "$FILE" outline` (existing — get the lay of the land first).
3. **Build incrementally.** One command, read the output, continue. After any structural op (new sheet, chart, named range, pivot), run `get` on it to confirm shape before stacking more on top.
4. **Format.** Column widths, number formats, freeze panes, tab colors, header fills. Formatting is not optional polish — per "Requirements for Outputs" it is part of the deliverable.
5. **Save, then reckon with the cache.** `officecli save <file>` writes to disk. Newly-added formulas ship without cached values; when a human opens the file in a spreadsheet app, the app recalculates and populates them. **But your downstream `INDEX/MATCH`, `SUMPRODUCT`, or any formula that references an upstream formula will cache whatever the upstream cached at write-time — often `0` or a stale value — and that cached lie survives into non-recalculating readers.** After any multi-formula build involving array formulas (`SUMPRODUCT`, `SUMIFS` with dynamic criteria) or cross-sheet chains, **re-touch every downstream cell** (run `set` again with the same formula) so the engine recomputes its cache from the freshly-cached upstream. ⚠️ Re-touch on cross-sheet chains via resident is unreliable (see Batch / resident caveats) — prefer non-resident `set` for the re-touch pass. Then `officecli get` a few downstream cells and eyeball that their `cachedValue=` is plausible. `validate` is safe with a resident open and itself flushes pending edits to disk (same as docx / pptx).
6. **QA — assume there are problems.** See the QA section. You are not done when your last command exited 0; you are done after one fix-and-verify cycle finds zero new issues.
## Quick Start
Minimal viable xlsx: 3 months of revenue + a total formula + column widths + a currency format. Adapt, don't copy-paste — your file, your data.
```bash
officecli create "$FILE"
officecli open "$FILE"
officecli set "$FILE" /Sheet1/A1 --prop value=Month --prop bold=true
officecli set "$FILE" /Sheet1/B1 --prop value=Revenue --prop bold=true
officecli set "$FILE" /Sheet1/A2 --prop value=Jan
officecli set "$FILE" /Sheet1/A3 --prop value=Feb
officecli set "$FILE" /Sheet1/A4 --prop value=Mar
officecli set "$FILE" /Sheet1/B2 --prop value=42000 --prop numFmt='$#,##0'
officecli set "$FILE" /Sheet1/B3 --prop value=45000 --prop numFmt='$#,##0'
officecli set "$FILE" /Sheet1/B4 --prop value=48000 --prop numFmt='$#,##0'
officecli set "$FILE" /Sheet1/A5 --prop value=Total --prop bold=true
officecli set "$FILE" /Sheet1/B5 --prop formula="SUM(B2:B4)" --prop bold=true --prop numFmt='$#,##0'
officecli set "$FILE" "/Sheet1/col[A]" --prop width=12
officecli set "$FILE" "/Sheet1/col[B]" --prop width=15
officecli close "$FILE"
officecli validate "$FILE"
```
Verified: `validate` returns `no errors found`, `B5` resolves to `135000`. This is the shape of every build: open → set cells/formulas → format → close → validate.
## CSV / bulk import
**Native `import` command (preferred for CSV/TSV).** Fastest path; loads a CSV into a sheet in one call. `--header` sets AutoFilter + freeze pane on row 1. Widths and `numFmt` still need a follow-up pass (per D-12 in Dashboard skill).
```bash
officecli import "$FILE" /Sheet1 --file data.csv --header
officecli import "$FILE" /Sheet1 --file data.tsv --format tsv --header
officecli import "$FILE" /Sheet1 --stdin --start-cell B2 < data.csv
```
**Python + batch fallback** — use when you need custom type coercion, formula injection, or the CSV lives inside another data pipeline. Recipe for 600-6000+ cells:
```python
# gen_batch.py — produces batch chunks of 80 value-set ops each
import csv, json
ops = []
with open("data.csv") as f:
reader = csv.reader(f)
for r, row in enumerate(reader, start=1):
for c, val in enumerate(row):
col = chr(ord('A') + c)
ops.append({"command":"set","path":f"/Data/{col}{r}",
"props":{"value": val}})
for i in range(0, len(ops), 80):
print(json.dumps(ops[i:i+80]))
```
```bash
python gen_batch.py | while IFS= read -r chunk; do
printf '%s\n' "$chunk" | officecli batch "$FILE"
done
```
Outcome: 648-row retail CSV (6490 cells) loads in ~30s, zero failures. Tune: start at 80 ops/chunk, drop to 40 if any chunk fails. Numeric type inference and formulas come later via targeted `set` — batch in this recipe is pure value injection.
## Reading & Analysis
Start wide, then narrow. `outline` first tells you what sheets exist and where the data is; jump into `view` / `get` / `query` only once you know where to look.
**Open the rendered workbook to eyeball your own work.**
- `officecli view $FILE html` — Read the returned HTML to audit the rendered output. Each sheet is addressable, charts render inline. Catches `###`, placeholder leakage, pivot layout, row-height clipping.
- `officecli watch $FILE` keeps a live preview running for the human user — they open it at their own discretion. Use when the user wants to watch along; agent self-check uses `view html` above.
Use `view html` as your **first visual check after a batch of edits** — fix at source. For final visual verification, the user opens the `.xlsx` in their Excel / WPS / Numbers viewer.
**Orient.** Sheets, dimensions, formula counts.
```bash
officecli view "$FILE" outline
```
**Extract.** Plain text dump for content QA or LLM context; scope with `--start` / `--end` / `--cols` for big files.
```bash
officecli view "$FILE" text --start 1 --end 50 --cols A,B,C
```
Other `view` modes worth knowing: `annotated` (cell values + types/formulas + warnings), `stats` (numeric summaries), `issues` (broken formulas, empty sheets, missing refs).
**Round-trip dump.** `officecli dump "$FILE" [path]` serializes the workbook — or one worksheet (`/Sheet1`, `/sheet[N]`) — into a replayable batch JSON; `officecli batch new.xlsx --input dump.json` replays it. Use it to learn from an existing workbook's structure or clone/adapt a template instead of reading raw OOXML. Coverage per `dump --help`; subtree dumps don't carry workbook-level resources (settings, named ranges) — the replay target must already define them.
```bash
officecli dump "$FILE" -o blueprint.json # whole workbook
officecli dump "$FILE" /Sheet1 -o sheet.json # one worksheet
officecli batch new.xlsx --input blueprint.json
```
**Inspect one element.** Use XPath-style paths. Always quote — shells glob `[N]`.
```bash
officecli get "$FILE" "/Sheet1/A1" # one cell
officecli get "$FILE" "/Sheet1/A1:D10" # range
officecli get "$FILE" "/Sheet1/chart[1]" # chart
officecli get "$FILE" "/Sheet1/table[1]" # ListObject
officecli get "$FILE" "/namedrange[1]" # workbook-level named range
```
Add `--depth N` to expand children; add `--json` for machine output. Full element list: `officecli help xlsx`.
**Query across the workbook.** CSS-like selectors. Use for systematic checks (formula coverage, error cells, empty headers) rather than hand-walking.
```bash
officecli query "$FILE" 'cell:has(formula)' # every formula cell
officecli query "$FILE" 'cell:contains("#REF!")' # broken references
officecli query "$FILE" 'cell[type=Number]' # typed filter
