microsoft-excel（微软 Excel）

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

      '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

Common Error Codes

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:

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