## Description

**Office Opener** is a Chrome extension designed to bridge the gap between modern browsers and local Microsoft Office file accessibility. Due to security restrictions in browsers like Chrome, Firefox, and the new Edge, direct linking to local files over HTTP(S) is typically blocked. This extension enables users to launch local Office documents seamlessly from web links, especially useful in corporate intranet environments.

The extension supports recent versions of Microsoft Office, primarily Microsoft 365 MSO (version 16.0.13530.20490 and later). Older versions such as Microsoft Office 2016 are not compatible due to incomplete URL-scheme support. For feedback and updates, users can visit the project's GitHub page.
