Convert DOCX to Base64 for APIs and Embedding

When working with APIs, you often need to encode Word documents as text strings. Base64 encoding makes this possible.

Use Cases

• Email APIs - SendGrid, Mailgun attachments
• Document APIs - DocuSign, Pandadoc integration
• Cloud storage - Storing in text-based systems
• Form submissions - AJAX file uploads

How to Use the Encoded Document

In JavaScript:

javascript
const formData = {
  document: "data:application/vnd.openxmlformats...;base64,UEsDBBQ..."
};
await fetch('/api/upload', {
  method: 'POST',
  body: JSON.stringify(formData)
});

In Python:

python
import base64
with open('document.docx', 'rb') as f:
    encoded = base64.b64encode(f.read())
