How to generate Office files from AWS Lambda with Python

​

Steps

1. Put your Doconda API key (dashboard → API keys) in the function’s DOCONDA_API_KEY environment variable, preferably from a secret rather than in code.
2. Package the dependency (Python 3.9 or later; its only dependency is httpx): pip install doconda -t package/ and add your lambda_function.py to the zip.
3. Write the handler:

from doconda import Doconda, DocondaError

doconda = Doconda()  # reads DOCONDA_API_KEY


def lambda_handler(event, context):
    try:
        doc = doconda.documents.create(
            format=event.get("format", "docx"),
            content={"markdown": event["markdown"]},
        )
    except DocondaError as e:
        return {"error": e.code, "status": e.status}

    return {
        "id": doc["id"],
        "status": doc["status"],
        "outputs": doc["outputs"],
    }

​

What you get back

{
  "id": "doc_01JAB3H8K2M7V6X5T1R0NPQ4ZW",
  "status": "ready",
  "outputs": [
    { "kind": "xlsx", "url": "https://…", "expires_at": "…" },
    { "kind": "pdf", "url": "https://…", "expires_at": "…" }
  ]
}

• outputs: the file and its PDF. Links expire after 5 minutes; documents.outputs(id) gives fresh ones.
• To store the file in S3: doconda.documents.download(doc["id"], "xlsx") returns the bytes.
• status: ready, ready_with_warnings, needs_review (check documents.report(id)) or failed (not charged).
