XLS Viewer - Open Excel XLS Files on Android & Online

An XLS spreadsheet reaches Android as HTML, PDF, JPG or PNG. One REST call renders the workbook in the cloud, and the app receives pages that show the rows, columns and cell formatting of the workbook.

XLS is the binary workbook format that Microsoft Excel used from 1997 to 2003, and files in it are still in daily use. Old accounting exports, ERP reports and shared price lists arrive as XLS attachments, and people read them on phones as often as on desktops.

Developers reach the same rendering from Java: the Android SDK is available as a Maven artifact or a Gradle dependency and ships with sample code. Requests may target one page at a time, thumbnails and zoom help with dense sheets, navigation moves through the workbook, protected files open with their password, and 180-plus formats share a single integration.

Reading one file takes no code at all, because the free GroupDocs.Viewer web app opens XLS in a browser tab. Developers get a free trial plus the interactive API Explorer for testing XLS rendering before they commit to an integration.
