# Open MS Office files in the browser using JavaScript

Use JavaScript to open Word, Excel, and PowerPoint documents directly on any browser — no external dependencies or MS Office licenses required. Documents can be opened from a number of input sources, including remote URLs, blobs, array buffers, local storage, and Base64 data. The opened Office document can be displayed in the viewer or processed in a headless environment, where it can be annotated, edited, converted, and more.
