    <p><strong>Convert a file to another format.</strong> Sends a document to CODE and returns binary data (pdf, png, docx, odt, html, xlsx, pptx …). Does not save to Nextcloud — result is <code>msg.payload</code> as a Buffer.</p>

    <h4>Input</h4>
    <p>File content, in order:</p>
    <ol>
        <li><code>msg.payload</code> if it's already a Buffer or text</li>
        <li>otherwise WebDAV GET of <code>msg.ncPath</code></li>
    </ol>
    <p>Optional: <code>msg.templateNcPath</code> (template), <code>msg.compareNcPath</code> (compare file).</p>

    <h4>Output</h4>
    <p>POST multipart to CODE <code>/cool/convert-to/&lt;format&gt;</code>. Field: <code>data</code> = source file.</p>
    <p><code>msg.payload</code>, <code>msg.filename</code>, <code>msg.format</code>, <code>msg.contentType</code>, <code>msg.statusCode</code></p>

    <h4>When to use</h4>
    <p>When you control the next step: save via WebDAV/OCS, email, Talk, or pass on in the flow. For "file in NC → PDF in NC" use <code>collabora-bridge</code> (<code>ncFileToPdf</code>).</p>

    <pre>inject { ncPath: "/Documents/contract.docx", format: "pdf" }
  → collabora-convert
  → debug (payload = PDF bytes)</pre>
