What is google-sheets?

A workflow for analyzing and editing Google Sheets with attention to exact spreadsheets, tabs, ranges, formulas, and charts.

It helps find spreadsheets, inspect and search data, plan formulas, clean tables, create or repair charts, and update specified cell ranges.

It reduces mistakes caused by changing the wrong cells or losing track of how tables and formulas are organized.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Model	Per session	Once invoked
Fable 5.1	$0.00060	$0.01218
Opus 5	$0.00030	$0.00609
Sonnet 5	$0.00012	$0.00244
Haiku 4.5	$0.00006	$0.00122

Security

Grade A, and why

google-sheets scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 9d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

How it starts

The opening of the file, as written. The whole thing — 90 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Google Sheets

Use this skill to keep spreadsheet work grounded in the exact spreadsheet, sheet, range, headers, and formulas that matter.

Purpose Of This File

This file is intentionally minimal and only covers:

routing to the right spreadsheet workflow
stateful operation and mandatory routing to reference files
live-read/search safety for direct connector calls

Detailed editing, formula, chart, upload, live-read/search, and batch-update rules live in references/. Latency is not a constraint for this skill, so always read the relevant reference files before performing the task. If the user has not provided explicit style direction, read references/style-profiles.md and apply the appropriate Google Sheets destination default before authoring workbook formatting.

Default Routing

New Google Sheets creation: first check whether the [@spreadsheets](plugin://spreadsheets@openai-primary-runtime) plugin or the $Excel skill is installed.
If either is installed, YOU MUST use [@spreadsheets](plugin://spreadsheets@openai-primary-runtime) or $Excel to create a local .xlsx. Then import the .xlsx into Drive as a native Google Sheets spreadsheet. Read references/reference-import-spreadsheet-to-native-sheets.md.
If neither skill is installed, create the spreadsheet directly with Google Sheets MCP.
Existing Google Sheets edits: use Google Sheets MCP directly.

Do not reference the local .xlsx in the final answer. Your final answer includes the Google Spreadsheet link only.

Canonical Workflow Bias

Prefer one simple proven workflow over a large tree of recovery branches. When a task matches a known successful pattern, follow that pattern directly instead of re-evaluating every possible fallback path. Do not let accumulated edge-case guardrails turn a straightforward Sheets task into a long blocker-analysis exercise.

For sheet creation and editing tasks, prefer this sequence when viable:

Gather the required source material.
Pick the correct default routing.
Establish the sheet checklist or sheet plan.
Build or edit the sheet.
Verify the sheet is clean, complete, native, and scannable.
Stop once the verified workflow has succeeded.

Changes

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
