Encodes a string or bytes as Base64.
class Utilities method .base64Encode()
Utilities is the Apps Script service.
.base64Encode() is the method name you will see after a dot in your code.
What it does
Why it's used
- Encode data for Basic auth headers or API payloads.
- Prepare binary content for safe text transport.
Common errors
- Forgetting parentheses on base64Encode. Write Utilities.base64Encode(), not Utilities.base64Encode or base64Encode by itself.
- Skipping dots between chained calls. Each step needs a dot, like Utilities.base64Encode().
- Adding spaces where they do not belong. Write Utilities.base64Encode(), not Utilities .base64Encode(), Utilities.base64Encode (), or Utilities . base64Encode().
- Wrong capitalization. Use Utilities and base64Encode, not utilities or base64encode.
