Productivity - Document Viewers (7)

LibreOffice is a complete productivity suite including word processor, spreadsheet, presentations, database, drawing tool and more. Includes strong compatibility for 100s of file formats including Microsoft Office (Word, Excel, PowerPoint, Visio etc.). The program is similar to OpenOffice, a program that it was derived from, but has added many new features and improvements.

LibreOffice Portable is a special build developed in conjunction with the publisher. On systems without Java installed, some functions such as document creation wizards and the Base database application etc. can be enabled by adding jPortable, though this is optional and can be skipped if those functions are not needed. Alternatively, X-LibreOffice is also available.

Other available portable versions:

• Still - more tested and stable but with fewer features/capabilities
• Legacy - for WinXP/Vista users (unsupported)

Sigil is a tabbed editor for the EPUB format commonly used in eBooks. The program includes basic formatting, customizable fonts and styles, hotkeys and spellcheck. You can generate a table of contents, embed files (audio, video, or other), edit/add metadata, rearrange or split pages, add vector (SVG) images and available "clips" for frequently entered text.

As the format is based on simple HTML, the program includes a WYSIWYG-style book vs. code view, the ability to modify cascading style sheets and additional functionality via plugins. The program can even shrink some eBooks by discarding unused media elements.

Cross-platform with clients for Linux, Mac and supports many languages. Sigil Portable is a wrapper version of the program and X-Sigil is also available.

FreeOffice is a fast and lightweight office suite with word processor, spreadsheet, and presentation tools. The interface supports themes, a dark mode, and classic or ribbon-style toolbars. All components include a wide variety of formatting, functions, and animation.

The program will import and export to standard Microsoft formats with reasonable fidelity. A pro version is also available with additional features (including 64-bit), as well as the previous version.

NOTE: The program will eventually require email registration, but a workaround is available.

CSVed is a fast, basic spreadsheet file editor that supports the CSV file format. You can add/delete columns, rearrange column order, change separator, filter items, remove duplicates, split/join columns etc.
