A command-line tool for working with Google Sheets, Google's online spreadsheets. It can manage cell data, worksheet tabs, formatting, filters, sorting, and row or column layout.

Use it to read or update cells, create or manage tabs, format headers, freeze rows or columns, resize columns, filter data, sort ranges, and add basic conditional formatting.

It removes repetitive manual spreadsheet editing and lets scripts apply the same data and formatting changes consistently.

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	$0.00156	$0.04002
Opus 5.5	$0.00062	$0.01601
Sonnet 5.5	$0.00031	$0.00800
Haiku 4.5	$0.00016	$0.00400

Security

Grade A, and why

gsheets scanned grade A with 1 finding 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 2mo ago.

The scan reads SKILL.md. This mod also ships 1 executable file (scripts/gsheets.py), listed below but not scanned — reading those needs a real analyzer, not pattern matching.

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.

How it starts

The opening of the file, as written. The whole thing — 272 lines — stays where its author put it; the contents beside it link to each section on GitHub.

gsheets

A single-file Python CLI (scripts/gsheets.py) over the Google Sheets API v4 covering data, tabs, structure, styling, filters/sort, and a raw-batchUpdate escape hatch. Sibling of gdoc-sync — same auth model, same retry semantics, different surface.

The script has one external dep beyond Python stdlib: pip install google-auth for service-account auth (recommended). Without it you can still use gcloud ADC, or install cryptography and the script will mint JWTs itself.

Quick start

# One-time: share the target Sheet with your service account as Editor.
# Then:
scripts/gsheets.py info <SPREADSHEET_ID> --sa-key ~/sa.json
scripts/gsheets.py write <SPREADSHEET_ID> --range "Sheet1!A1" \
  --values-json '[["name","status"],["alpha","ok"],["beta","fail"]]' \
  --sa-key ~/sa.json
scripts/gsheets.py format-header <SPREADSHEET_ID> --tab Sheet1 \
  --bg "#1a73e8" --fg "#ffffff" --filter \
  --sa-key ~/sa.json

SPREADSHEET_ID is the long token in the URL: https://docs.google.com/spreadsheets/d/<SPREADSHEET_ID>/edit.

Skip --sa-key to fall back to gcloud auth application-default print-access-token (needs prior gcloud auth application-default login --scopes=...spreadsheets,...drive). Service-account auth is more reliable — see reference/auth-setup.md.

Conceptual model

A Google Sheets file is a spreadsheet. It contains one or more sheets (aka tabs or worksheets). Each sheet is a grid of cells. Three IDs / names matter:

Identifier	Where from	Used by
spreadsheetId	URL: `/spreadsheets/d/<ID>/edit`	Every subcommand (first positional arg)
sheet title (e.g. `"Sheet1"`, `"Review"`)	What you see on the tab strip	A1-notation ranges (`"Review!A1:C10"`); `--tab` flag
sheetId (integer)	`list-tabs` output	The raw `batchUpdate` API — but the CLI resolves titles for you, so you rarely need it directly

A1 notation vs GridRange: the values.* endpoints (read/write/append/clear) take A1 strings. Everything else (formatting, structure, filters) takes a numeric GridRange — but the CLI lets you pass A1 + --tab and translates it internally.

What ships with it

7 files beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.

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.

gsheets is a skill published in the GitHub repository shaharsha/claude-skills (6 stars, last pushed today), licensed MIT. It adds 156 tokens to every session and 4,002 once invoked, about $0.0006 per session on Opus 5.5. A static security scan graded it A with 1 finding (makes network calls). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-31.
