Microsoft Excel

Access the Microsoft Excel API (via Microsoft Graph) with managed OAuth authentication. Read and write workbooks, worksheets, ranges, tables, and charts stored in OneDrive or SharePoint.

Quick Start

# List worksheets in a workbook
python <<'EOF'
import urllib.request, os, json
req = urllib.request.Request('https://api.maton.ai/microsoft-excel/v1.0/me/drive/root:/workbook.xlsx:/workbook/worksheets')
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/microsoft-excel/{native-api-path}

Maton proxies requests to graph.microsoft.com and automatically injects your OAuth token.

Authentication

All requests require the Maton API key in the Authorization header:

Authorization: Bearer $MATON_API_KEY

Environment Variable: Set your API key as MATON_API_KEY:

export MATON_API_KEY="YOUR_API_KEY"

Getting Your API Key

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

Connection Management

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

List Connections

python <<'EOF'
import urllib.request, os, json
req = urllib.request.Request('https://api.maton.ai/connections?app=microsoft-excel&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

python <<'EOF'
import urllib.request, os, json
data = json.dumps({'app': 'microsoft-excel'}).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

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": "2026-02-07T00:43:18.565932Z",
    "last_updated_time": "2026-02-07T00:43:29.729782Z",
    "url": "https://connect.maton.ai/?session_token=...",
    "app": "microsoft-excel",
    "metadata": {}
  }
}

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

Delete Connection

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 Microsoft Excel connections, specify which one to use with the Maton-Connection header:

python <<'EOF'
import urllib.request, os, json
req = urllib.request.Request('https://api.maton.ai/microsoft-excel/v1.0/me/drive')
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 include this header to ensure requests go to the intended account.

Workbook Access Patterns

You can access workbooks using either ID-based or path-based patterns:

By File ID:

/microsoft-excel/v1.0/me/drive/items/{file-id}/workbook/...

By File Path:

/microsoft-excel/v1.0/me/drive/root:/{path-to-file}:/workbook/...

Security & Permissions

• Access is scoped to workbooks, worksheets, tables, and cell data within the connected Microsoft Excel 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

const response = await fetch(
  "https://api.maton.ai/microsoft-excel/v1.0/me/drive/root:/data.xlsx:/workbook/worksheets('Sheet1')/range(address='A1:B10')",
  {
    headers: {
      'Authorization': `Bearer ${process.env.MATON_API_KEY}`
    }
  }
);
const data = await response.json();
console.log(data.values);

Python

import os
import requests

# Update range values
response = requests.patch(
    "https://api.maton.ai/microsoft-excel/v1.0/me/drive/root:/data.xlsx:/workbook/worksheets('Sheet1')/range(address='A1:B2')",
    headers={'Authorization': f'Bearer {os.environ["MATON_API_KEY"]}'},
    json={'values': [['Name', 'Age'], ['Alice', 30]]}
)
print(response.json())

Notes

• Only .xlsx files are supported (not legacy .xls)
• Worksheet names with special characters need URL encoding
• Table and worksheet IDs containing { and } must be URL-encoded (%7B and %7D)
• Sessions expire after ~5 minutes of inactivity (persistent) or ~7 minutes (non-persistent)
• Use null in value arrays to skip updating specific cells
• Blank cells should use "" (empty string)
• Range addresses use A1 notation (e.g., A1:C10, Sheet1!A1:B5)
• IMPORTANT: When using curl commands, use curl -g when URLs contain parentheses 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

Error Handling

Status	Meaning
400	Missing Microsoft Excel connection or invalid request
401	Invalid or missing Maton API key
404	Item not found or session expired
429	Rate limited
4xx/5xx	Passthrough error from Microsoft Graph API

Common Error Codes

Code	Description
ItemNotFound	File or resource doesn't exist
ItemAlreadyExists	Worksheet or table with that name already exists
InvalidArgument	Invalid parameter or missing required field
SessionNotFound	Session expired or doesn't exist

Troubleshooting: API Key Issues

1. Check that the MATON_API_KEY environment variable is set:

echo $MATON_API_KEY

1. 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 microsoft-excel. For example:

2. Correct: https://api.maton.ai/microsoft-excel/v1.0/me/drive/root:/workbook.xlsx:/workbook/worksheets

3. Incorrect: https://api.maton.ai/v1.0/me/drive/root:/workbook.xlsx:/workbook/worksheets

這個 Skill 質量不錯，文件寫得很詳細，所有常用的 Excel 操作都有覆蓋，使用示例也比較實用。優點是 API 說明清晰、程式碼示例豐富、錯誤處理到位；不足之處是文件偏技術向，缺少通俗的常見問題解答，對普通使用者不夠友好，另外缺少一些實際使用場景的操作示例。總體來說，這是一個功能完整、文件規範的 Skill，但還有完善空間。
