OpenDocument Reader is a document viewer and editor by Stefl und Taschauer OG that lets you open, read, and modify ODF files on your Android device. It is designed to work with files created by office suites like LibreOffice and OpenOffice, handling formats such as ODT for text and ODS for spreadsheets.

Beyond ODF documents, the app provides broad compatibility with many other file types, including PDFs, Microsoft Office files, and various image and text formats. It focuses on on-device processing, so your documents are never uploaded anywhere, which is a strong point for privacy-conscious users who need to handle sensitive information while on the go.

The software is open source and functions fully offline, allowing you to view and edit content without an internet connection. Whether you need to quickly check notes, fix a typo in a report, or search through a spreadsheet, the app offers a clean and straightforward interface for these tasks.

Latest changes

The latest release brings the ability to add or remove rows and columns in spreadsheets, along with support for editing and saving CSV files. When you save after an edit, formulas that had become outdated are now refreshed. Printing now follows the document's own paper size and orientation, placing one page per sheet, and a PDF prints as the file itself. In addition, some Word, Excel and PowerPoint files received from mail and file apps open in the app again, and the read-aloud feature uses the language of the document.
