Google Sheets

Access the Google Sheets API with managed OAuth authentication. Read and write spreadsheet values, create sheets, apply formatting, and perform batch operations.

Quick Start

CLI:

maton google-sheets values get <spreadsheetId> --range 'Sheet1!A1:D10'

maton api '/google-sheets/v4/spreadsheets/SPREADSHEET_ID/values/Sheet1%21A1%3AD10'

Python:

python <<'EOF'
import urllib.request, os, json
req = urllib.request.Request('https://api.maton.ai/google-sheets/v4/spreadsheets/SPREADSHEET_ID/values/Sheet1%21A1%3AD10')
req.add_header('Authorization', f'Bearer {os.environ["MATON_API_KEY"]}')
print(json.dumps(json.load(urllib.request.urlopen(req)), indent=2))
EOF

Base URL

https://api.maton.ai/google-sheets/{native-api-path}

Maton proxies requests to sheets.googleapis.com and automatically injects your OAuth token.

Installation

NPM:

npm install -g @maton-ai/cli

Homebrew:

brew install maton-ai/cli/maton

Authentication

CLI:

maton login                          # Opens browser for API key
maton login --interactive            # Skip browser, paste API key directly
maton whoami                         # Show current auth state

Manual:

1. Sign in or create an account at maton.ai
2. Go to maton.ai/settings
3. Copy your API key
4. Set your API key as MATON_API_KEY:

export MATON_API_KEY="YOUR_API_KEY"

Connection Management

Manage your Google OAuth connections at https://api.maton.ai.

List Connections

CLI:

maton connection list google-sheets --status ACTIVE

maton api -X GET /connections -f app=google-sheets -f status=ACTIVE

Python:

python <<'EOF'
import urllib.request, os, json
req = urllib.request.Request('https://api.maton.ai/connections?app=google-sheets&status=ACTIVE')
req.add_header('Authorization', f'Bearer {os.environ["MATON_API_KEY"]}')
print(json.dumps(json.load(urllib.request.urlopen(req)), indent=2))
EOF

Create Connection

CLI:

maton connection create google-sheets

maton api /connections -f app=google-sheets

Python:

python <<'EOF'
import urllib.request, os, json
data = json.dumps({'app': 'google-sheets'}).encode()
req = urllib.request.Request('https://api.maton.ai/connections', data=data, method='POST')
req.add_header('Authorization', f'Bearer {os.environ["MATON_API_KEY"]}')
req.add_header('Content-Type', 'application/json')
print(json.dumps(json.load(urllib.request.urlopen(req)), indent=2))
EOF

Get Connection

CLI:

maton connection view {connection_id}

maton api /connections/{connection_id}

Python:

python <<'EOF'
import urllib.request, os, json
req = urllib.request.Request('https://api.maton.ai/connections/{connection_id}')
req.add_header('Authorization', f'Bearer {os.environ["MATON_API_KEY"]}')
print(json.dumps(json.load(urllib.request.urlopen(req)), indent=2))
EOF

Response:

{
  "connection": {
    "connection_id": "{connection_id}",
    "status": "ACTIVE",
    "creation_time": "2025-12-08T07:20:53.488460Z",
    "last_updated_time": "2026-01-31T20:03:32.593153Z",
    "url": "https://connect.maton.ai/?session_token=...",
    "app": "google-sheets",
    "metadata": {}
  }
}

Open the returned url in a browser to complete OAuth authorization.

Delete Connection

CLI:

maton connection delete {connection_id}

maton api -X DELETE /connections/{connection_id}

Python:

python <<'EOF'
import urllib.request, os, json
req = urllib.request.Request('https://api.maton.ai/connections/{connection_id}', method='DELETE')
req.add_header('Authorization', f'Bearer {os.environ["MATON_API_KEY"]}')
print(json.dumps(json.load(urllib.request.urlopen(req)), indent=2))
EOF

Specifying Connection

If you have multiple Google accounts connected, specify which one to use:

CLI:

maton google-sheets spreadsheet view <spreadsheetId> --connection {connection_id}

maton api /google-sheets/v4/spreadsheets/SPREADSHEET_ID --connection {connection_id}

Python:

python <<'EOF'
import urllib.request, os, json
req = urllib.request.Request('https://api.maton.ai/google-sheets/v4/spreadsheets/SPREADSHEET_ID')
req.add_header('Authorization', f'Bearer {os.environ["MATON_API_KEY"]}')
req.add_header('Maton-Connection', '{connection_id}')
print(json.dumps(json.load(urllib.request.urlopen(req)), indent=2))
EOF

If you have multiple connections, always specify the connection to ensure requests go to the intended account.

Security & Permissions

• Access is scoped to spreadsheets, sheets, cells, and data ranges within the connected Google Sheets account.
• All write operations require explicit user approval. Before executing any create, update, or delete call, confirm the target resource and intended effect with the user.

Code Examples

CLI

# Read values from a spreadsheet
maton google-sheets values get <spreadsheetId> --range 'Sheet1!A1:B10'

# Filter with jq — e.g., extract just the values array
maton google-sheets values get <spreadsheetId> --range 'Sheet1!A1:B10' --json --jq '.values'

# Append a row
maton google-sheets values append <spreadsheetId> --range A1 --values 'Alice,100,true'

JavaScript

// Read values
const response = await fetch(
  'https://api.maton.ai/google-sheets/v4/spreadsheets/SHEET_ID/values/Sheet1!A1:D10',
  {
    headers: {
      'Authorization': `Bearer ${process.env.MATON_API_KEY}`
    }
  }
);

// Write values
await fetch(
  'https://api.maton.ai/google-sheets/v4/spreadsheets/SHEET_ID/values/Sheet1!A1:B2?valueInputOption=USER_ENTERED',
  {
    method: 'PUT',
    headers: {
      'Content-Type': 'application/json',
      'Authorization': `Bearer ${process.env.MATON_API_KEY}`
    },
    body: JSON.stringify({
      values: [['A1', 'B1'], ['A2', 'B2']]
    })
  }
);

Python

import os
import requests

# Read values
response = requests.get(
    'https://api.maton.ai/google-sheets/v4/spreadsheets/SHEET_ID/values/Sheet1!A1:D10',
    headers={'Authorization': f'Bearer {os.environ["MATON_API_KEY"]}'}
)

# Write values
response = requests.put(
    'https://api.maton.ai/google-sheets/v4/spreadsheets/SHEET_ID/values/Sheet1!A1:B2',
    headers={'Authorization': f'Bearer {os.environ["MATON_API_KEY"]}'},
    params={'valueInputOption': 'USER_ENTERED'},
    json={'values': [['A1', 'B1'], ['A2', 'B2']]}
)

Notes

• When using curl, ranges in URL paths must be URL-encoded (! -> %21, : -> %3A). JavaScript fetch and Python requests handle encoding automatically.
• Use valueInputOption=USER_ENTERED to parse formulas and numbers
• Delete spreadsheets via the Google Drive API, not Sheets API
• Sheet IDs are numeric and found in the spreadsheet metadata
• IMPORTANT: When using curl commands, use curl -g when URLs contain brackets (fields[], sort[], records[]) to disable glob parsing
• IMPORTANT: When piping curl output to jq or other commands, environment variables like $MATON_API_KEY may not expand correctly in some shell environments. You may get "Invalid API key" errors when piping.

Error Handling

Status	Meaning
400	Missing Google Sheets connection
401	Invalid or missing Maton API key
429	Rate limited (10 req/sec per account)
4xx/5xx	Passthrough error from Google Sheets API

Troubleshooting: API Key Issues

CLI:

1. Check your auth state:

maton whoami

2. Verify the API key is valid by listing connections:

maton connection list

Manual:

1. Check that the MATON_API_KEY environment variable is set:

echo $MATON_API_KEY

2. Verify the API key is valid by listing connections:

python <<'EOF'
import urllib.request, os, json
req = urllib.request.Request('https://api.maton.ai/connections')
req.add_header('Authorization', f'Bearer {os.environ["MATON_API_KEY"]}')
print(json.dumps(json.load(urllib.request.urlopen(req)), indent=2))
EOF

Troubleshooting: Invalid App Name

1. Ensure your URL path starts with google-sheets. For example:

• Correct: https://api.maton.ai/google-sheets/v4/spreadsheets/SPREADSHEET_ID
• Incorrect: https://api.maton.ai/v4/spreadsheets/SPREADSHEET_ID
