Collabora Office Classic arrives on Android devices as an open-source mobile office suite built to handle digital documents, spreadsheets, presentations, and vector graphics.
Developed using LibreOffice technology, the application supplies core workplace, educational, and administrative processing tools.
Four Core Modules Power Office Workflows
The suite organizes its core functionality across four distinct modules tailored for specific tasks. The Writer module handles text document creation and editing for letters, reports, papers, and articles. Meanwhile, the Calc module provides electronic spreadsheet capabilities for processing numeric and textual data through tables, formulas, and automated calculations.
For presentations, the Impress module builds slide decks incorporating text, images, charts, and tables.
The Draw module creates illustrations, diagrams, flowcharts, organization charts, and simple drawings while managing various visual objects.
Formatting, Templates, and Offline Editing Capabilities
Beyond its primary modules, the application includes extensive formatting and utility options for document management.
Users can format text with adjustable fonts, sizes, colors, bolding, italics, underlines, and paragraph alignments. The table tool manages rows and columns, cell merging, and borders, while Calc supports formulas like SUM, AVERAGE, COUNT, MAX, and MIN. Additional tools include ready-to-use templates, a spelling checker, offline local document editing, PDF export, and page layout configurations. Page layout and page setup features help users customize the document appearance before printing or sharing.
Extended Text Processing and File Compatibility
Collabora Office documentation details how Collabora Office Writer further extends text processing with support for the standardized OpenDocument Format (ODF), Microsoft Word .doc format, and HTML.
The application integrates advanced layout features such as a Style Window for modifying paragraph and page designs, a Navigator tool for document outlining, desktop publishing tools for multi-column brochures, and a built-in Gallery for inserting graphics, clip art, and Fontwork special effects. Users can convert spreadsheet data into bar, line, and pie charts while operating offline without requiring an active internet connection.
Advanced Writing and Customization Features
Collabora Office Writer supports simple documents like memos, fax messages, résumés, and mail merges, alongside long multi-part files complete with bibliographies, reference tables, and indexes. Built-in writing utilities include a thesaurus, AutoCorrect, and hyphenation. Users can also create custom templates using a wizard.
For graphical content, users can insert images in formats such as JPG and GIF directly into text documents. The flexible application interface allows users to customize icons and menus according to their preferences.
