SharePoint by @altf1be

Interact with SharePoint document libraries via Microsoft Graph API using certificate-based authentication.

Setup

1. Create an Entra app with Sites.Selected permission and certificate auth
2. Grant site-level write access via Microsoft Graph PowerShell
3. Set environment variables (or create .env in {baseDir}):

SP_TENANT_ID=your-azure-tenant-id
SP_CLIENT_ID=your-app-client-id
SP_CERT_PATH=/path/to/certificate.pem
SP_SITE_ID=your-sharepoint-site-id
SP_DRIVE_ID=optional-specific-drive-id

4. Install dependencies: cd {baseDir} && npm install

Commands

File operations

# Show site and drive info
node {baseDir}/scripts/sharepoint.mjs info

# List files in library root
node {baseDir}/scripts/sharepoint.mjs list

# List files in a subfolder
node {baseDir}/scripts/sharepoint.mjs list --path "Meeting Notes/2026"

# Read file content (extracts text from Office formats)
node {baseDir}/scripts/sharepoint.mjs read --path "Report.docx"

# Upload a file
node {baseDir}/scripts/sharepoint.mjs upload --local ./report.docx --remote "Reports/Q1-2026.docx"

# Search for files
node {baseDir}/scripts/sharepoint.mjs search --query "quarterly review"

# Create folder
node {baseDir}/scripts/sharepoint.mjs mkdir --path "Meeting Notes/2026"

# Delete (requires --confirm flag)
node {baseDir}/scripts/sharepoint.mjs delete --path "Drafts/old-file.txt" --confirm

Coauthoring (checkout/checkin)

# Safe edit: checkout → upload modified file → checkin (recommended)
node {baseDir}/scripts/sharepoint.mjs edit --path "Report.docx" --local ./modified.docx --comment "Updated summary"

# Check out a file (lock for exclusive editing)
node {baseDir}/scripts/sharepoint.mjs checkout --path "Report.docx"

# Check in a file (unlock + publish)
node {baseDir}/scripts/sharepoint.mjs checkin --path "Report.docx" --comment "Reviewed and approved"

# Get an edit link to open in Office Online
node {baseDir}/scripts/sharepoint.mjs edit-link --path "Report.docx"

Supported Office formats

The read command extracts text content from:

• .docx → full text extraction via mammoth
• .xlsx → sheet names + cell data via exceljs
• .pptx → slide text extraction via jszip
• .pdf → text extraction via pdf-parse
• .txt / .md → raw content

Output is plain text suitable for AI processing (summarization, reformatting, action item extraction).

Dependencies

• @azure/identity — certificate-based Azure AD authentication
• @microsoft/microsoft-graph-client — Microsoft Graph API client
• mammoth — Word document text extraction
• exceljs — Excel spreadsheet parsing
• jszip — PowerPoint XML extraction
• pdf-parse — PDF text extraction
• commander — CLI framework
• dotenv — environment variable loading

Security

• Certificate auth only (no client secrets, no passwords)
• Sites.Selected permission (access limited to one SharePoint site)
• Path traversal prevention: ../ is rejected
• Delete requires explicit --confirm flag
• No tokens or secrets printed to stdout
• File size limit: configurable max (default 50MB)

Full setup guide

For complete setup from scratch (Entra app, certificate, Sites.Selected, Key Vault): See the GitHub repository README.
