+title: Office
+---
+
+Gotenberg provides the endpoint `/convert/office` for Office document conversions.
+
+It accepts `POST` requests with a `multipart/form-data` Content-Type.
+
+## Basic
+
+You may send one or more Office documents. Following file extensions are accepted:
+
+* `.txt`
+* `.rtf`
+* `.doc`
+* `.docx`
+* `.odt`
+* `.xls`
+* `.xlsx`
+* `.ods`
+* `.ppt`
+* `.pptx`
+* `.odp`
+
+All files will be merged into a single resulting PDF.
+
+> **Attention:** currently, `unoconv` cannot perform concurrent conversions.
+> That's why for Office conversions, the API does only one conversion at a time.
+> See the [scalability section](#scalability) to find how to mitigate this issue.

+
+func main() {
+    c := &gotenberg.Client{Hostname: "http://localhost:3000"}
+    req, _ := gotenberg.NewOfficeRequest("document.docx", "document2.docx")
+    dest := "result.pdf"
+    c.Store(req, dest)
+}
+```
+
+### PHP
+
+```php
+use TheCodingMachine\Gotenberg\Client;
+use TheCodingMachine\Gotenberg\DocumentFactory;
+use TheCodingMachine\Gotenberg\OfficeRequest;
+
+$client = new Client('http://localhost:3000', new \Http\Adapter\Guzzle6\Client());
+$files = [
+    DocumentFactory::makeFromPath('document.docx', 'document.docx'),
+    DocumentFactory::makeFromPath('document2.docx', 'document2.docx'),
+];
+$request = new OfficeRequest($files);
+$dest = "result.pdf";
+$filename = $client->store($request, $dest);
+```
+
+## Orientation
+
+You may also customize the resulting PDF format.
+
+By default, it will be rendered with `portrait` orientation.
