Google Sheets

Interact with Google Sheets for spreadsheet management, data manipulation, and formula operations.

Installation

Dependencies: pip install --user google-auth google-auth-oauthlib google-api-python-client keyring pyyaml

Setup Verification

After installation, verify the skill is properly configured:

$SKILL_DIR/scripts/google-sheets.py check

This will check:

Python dependencies (google-auth, google-auth-oauthlib, google-api-python-client, keyring, pyyaml)
Authentication configuration
Connectivity to Google Sheets API

If anything is missing, the check command will provide setup instructions.

Authentication

Google Sheets uses OAuth 2.0 for authentication. For complete setup instructions, see:

GCP Project Setup Guide - Create project, enable Sheets API
Google OAuth Setup Guide - Configure credentials

Quick Start

Create ~/.config/agent-skills/google.yaml:

oauth_client:
  client_id: your-client-id.apps.googleusercontent.com
  client_secret: your-client-secret

Run $SKILL_DIR/scripts/google-sheets.py check to trigger OAuth flow and verify setup.

On scope or authentication errors, see the OAuth troubleshooting guide.

Commands

check

Verify configuration and connectivity.

$SKILL_DIR/scripts/google-sheets.py check

This validates:

Python dependencies are installed
Authentication is configured
Can connect to Google Sheets API
Creates a test spreadsheet to verify write access

auth setup

Store OAuth 2.0 client credentials for custom OAuth flow.

$SKILL_DIR/scripts/google-sheets.py auth setup \
  --client-id YOUR_CLIENT_ID \
  --client-secret YOUR_CLIENT_SECRET

Credentials are saved to ~/.config/agent-skills/google-sheets.yaml.

Options:

--client-id - OAuth 2.0 client ID (required)
--client-secret - OAuth 2.0 client secret (required)

auth reset

Clear stored OAuth token. The next command that needs authentication will trigger re-authentication automatically.

$SKILL_DIR/scripts/google-sheets.py auth reset

Use this when you encounter scope or authentication errors.

auth status

Show current OAuth token information without making API calls.

$SKILL_DIR/scripts/google-sheets.py auth status

Displays: whether a token is stored, granted scopes, refresh token presence, token expiry, and client ID.

#!/bin/bash
SS_ID="your-spreadsheet-id"

# Clear old data
$SKILL_DIR/scripts/google-sheets.py values clear $SS_ID --range "Sheet1!A1:Z1000"

# Write new data in batches
$SKILL_DIR/scripts/google-sheets.py values write $SS_ID \

  --values '[["Date","Revenue","Expenses","Profit"]]'

for month in Jan Feb Mar; do
  $SKILL_DIR/scripts/google-sheets.py values append $SS_ID \
    --range "Sheet1" \
    --values "[[\"\$month\",10000,7000,\"=B${ROW}-C${ROW}\"]]"
done

Error Handling

Authentication and scope errors are not retryable. If a command fails with an authentication error, insufficient scope error, or permission denied error (exit code 1), stop and inform the user. Do not retry or attempt to fix the issue autonomously — these errors require user interaction (browser-based OAuth consent). Point the user to the OAuth troubleshooting guide.

Retryable errors: Rate limiting (HTTP 429) and temporary server errors (HTTP 5xx) may succeed on retry after a brief wait. All other errors should be reported to the user.

Model Guidance

This skill makes API calls requiring structured input/output. A standard-capability model is recommended.

Troubleshooting

Cannot find spreadsheet

Make sure you're using the correct spreadsheet ID from the URL:

URL: https://docs.google.com/spreadsheets/d/1abc...xyz/edit
Spreadsheet ID: 1abc...xyz

Invalid range errors

Use proper A1 notation: Sheet1!A1:D5
Sheet names with spaces need quotes: 'My Sheet'!A1:B2
See references/range-notation.md for details

JSON parsing errors for --values

Ensure proper JSON escaping:

# Correct
--values '[["Hello","World"]]'
--values "[[\"Name\",\"Age\"]]"

# Incorrect
--values [[Hello,World]]  # Missing quotes

Sheet ID vs Sheet Title

Commands use different identifiers:

sheets create - Uses title (string)
sheets delete - Uses sheet ID (number)
Use spreadsheets get to find sheet IDs
