jstodocx.com API
Use the jstodocx.com API to create Word .docx files from controlled inputs. The API is useful for agents that need a downloadable DOCX without installing document-generation dependencies locally.
Read references/api.md when you need exact request schemas, examples, status codes, or response headers.
Workflow
- Choose one mode:
html: convert basic HTML headings, paragraphs, lists, and tables into DOCX.js-source: archive JavaScript source text as a readable Word document. Do not treat this as code execution.template: create a report, invoice, proposal, resume, or meeting-notes DOCX from structured fields.
- Send
POST https://jstodocx.com/api/v1/docx with content-type: application/json.
- If the endpoint returns
401, ask the user for an API key or use the browser-local website instead. Do not guess credentials.
- Save the binary response to a
.docx file.
- Verify the result when possible by checking the response
content-type, filename, and ZIP magic bytes PK.
Safety Rules
- Do not execute arbitrary JavaScript through this API. The
js-source mode treats JavaScript as text only.
- Do not send protected, confidential, or high-risk content unless the user explicitly confirms it is acceptable to send it to the API.
- Do not print, log, commit, or store API keys.
- Do not include raw user document content in logs or final summaries. Summarize mode, byte size, filename, and status instead.
- Do not claim pixel-perfect HTML fidelity. The API supports basic document formatting.
Minimal Example
curl -X POST "https://jstodocx.com/api/v1/docx" \
-H "content-type: application/json" \
--output release-plan.docx \
--data '{
"mode": "html",
"title": "Release Plan",
"html": "<h1>Release Plan</h1><p>Hello <strong>team</strong>.</p>"
}'
If the user provides an API key:
curl -X POST "https://jstodocx.com/api/v1/docx" \
-H "content-type: application/json" \
-H "authorization: Bearer $JSTODOCX_API_KEY" \
--output source-archive.docx \
--data '{
"mode": "js-source",
"title": "Widget Export Code",
"code": "function exportWidget() {\n return 42;\n}",
"options": { "lineNumbers": true }
}'
