1. Document Conversion API

Convert between PDF and Word/Excel/PPT, supporting 4 conversion types. 注：curl/服务端调用请用 JSON 格式（Cloudflare 平台会拦截非浏览器客户端的表单类 POST；浏览器端 multipart 不受影响）。

Request Parameters

Field	Type	Description
file	File	File to convert (max 50MB). JSON 格式: `{"name":"document.pdf","data":"<base64>"}`
type	String	Conversion type: `pdf-to-word` / `pdf-to-excel` / `word-to-pdf` / `excel-to-pdf` / `ppt-to-pdf`

Example (curl, JSON mode)

curl -X POST https://docsall.com/api/v1/external/convert \
  -H "Authorization: Bearer da_xxx" \
  -H "Content-Type: application/json" \
  -d '{"type":"pdf-to-word","file":{"name":"document.pdf","data":"'$(base64 -w0 document.pdf)'"}}' \
