# WebDAV and Office editing

Comind.work supports in-place editing of Microsoft Office documents through WebDAV integration. Open Word, Excel, or PowerPoint files directly from a record, edit them in your desktop Office application, and save changes back to Comind.work - without downloading and re-uploading.

## How it works[​](#how-it-works "Direct link to How it works")

WebDAV (Web Distributed Authoring and Versioning) is a protocol that allows editing files on a remote server as if they were local. Comind.work includes a built-in WebDAV server that exposes attached files to Office applications.

The workflow:

1. Open a record that has an attached Office document
2. Click **View in Office** (or **Edit in Office**) on the file attachment
3. The file opens in your desktop Microsoft Office application (Word, Excel, or PowerPoint)
4. Edit the document as usual
5. Save in Office - changes are written back to Comind.work automatically
6. Close the document when done

## Supported file types[​](#supported-file-types "Direct link to Supported file types")

| Extension       | Application          |
| --------------- | -------------------- |
| `.docx`, `.doc` | Microsoft Word       |
| `.xlsx`, `.xls` | Microsoft Excel      |
| `.pptx`, `.ppt` | Microsoft PowerPoint |
| `.rtf`          | Microsoft Word       |
| `.csv`          | Microsoft Excel      |

Other common Office-compatible formats are also supported via WebDAV.

## Requirements[​](#requirements "Direct link to Requirements")

* **Desktop Microsoft Office** - WebDAV editing requires a locally installed Office application. Office Online (browser-based) is not supported.
* **Browser support** - WebDAV links use a protocol handler that may require browser configuration or approval on first use.
* **Network access** - your Office application must be able to reach the Comind.work server directly over the network.

## Server configuration[​](#server-configuration "Direct link to Server configuration")

WebDAV runs as part of the Comind.work backend infrastructure.

For self-hosted installations, ensure that:

* WebDAV endpoints are accessible through your reverse proxy
* SSL/TLS is properly configured (Office applications may refuse non-HTTPS WebDAV connections)
* Authentication tokens are passed through correctly

## Things to know[​](#things-to-know "Direct link to Things to know")

* There is no file locking - if multiple users edit the same file simultaneously, the last save wins
* If your corporate firewall blocks WebDAV traffic, ask your network administrator to allow WebDAV connections to the Comind.work server
