# Format Conversion

In the context of the university's [[nextcloud]] and [[onlyoffice]] integration, **Format Conversion** refers to the process of updating legacy Office file formats to modern standards to enable browser-based editing.

## Requirements for Editing
The [[onlyoffice]] document server requires modern file formats to function and only supports the editing of current file formats. Legacy formats, such as the older `.doc` (Word) files, are not directly editable in their original state and must be converted to modern formats, such as `.docx`, before they can be modified.

## Process and Implementation
Users must convert these legacy files into modern equivalents. This conversion process can be executed and performed directly within the Nextcloud web interface, allowing users to upgrade their documents and transition files to editable formats without needing external software.
