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

bash
# List worksheets in a workbook
python <<'EOF'
import urllib.request, os, json
req = urllib.request.Request('https://gateway.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://gateway.maton.ai/microsoft-excel/{native-api-path}

Replace {native-api-path} with the actual Microsoft Graph API endpoint path. The gateway 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:

bash
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://ctrl.maton.ai.

List Connections

bash
python <<'EOF'
import urllib.request, os, json
req = urllib.request.Request('https://ctrl.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

bash
python <<'EOF'
import urllib.request, os, json
data = json.dumps({'app': 'microsoft-excel'}).encode()
req = urllib.request.Request('https://ctrl.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

bash
python <<'EOF'
import urllib.request, os, json
req = urllib.request.Request('https://ctrl.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:

json
{
  "connection": {
    "connection_id": "4751ac89-3970-47e1-872c-eacdf4291732",
    "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

bash
python <<'EOF'
import urllib.request, os, json
req = urllib.request.Request('https://ctrl.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:

bash
python <<'EOF'
import urllib.request, os, json
req = urllib.request.Request('https://gateway.maton.ai/microsoft-excel/v1.0/me/drive')
req.add_header('Authorization', f'Bearer {os.environ["MATON_API_KEY"]}')
req.add_header('Maton-Connection', '4751ac89-3970-47e1-872c-eacdf4291732')
print(json.dumps(json.load(urllib.request.urlopen(req)), indent=2))
EOF

If omitted, the gateway uses the default (oldest) active connection.

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/...

  {
    headers: {
      'Authorization': `Bearer ${process.env.MATON_API_KEY}`
    }
  }
);
const data = await response.json();
console.log(data.values);

Python

python
import os
import requests

# Update range values
response = requests.patch(
    "https://gateway.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:
bash
echo $MATON_API_KEY
  1. Verify the API key is valid by listing connections:
bash
python <<'EOF'
import urllib.request, os, json
req = urllib.request.Request('https://ctrl.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://gateway.maton.ai/microsoft-excel/v1.0/me/drive/root:/workbook.xlsx:/workbook/worksheets
  • Incorrect: https://gateway.maton.ai/v1.0/me/drive/root:/workbook.xlsx:/workbook/worksheets
