What is Open Office?

OpenOffice is an open source office productivity suite. It encompasses a variety of applications such as a word processor, spreadsheet application, and presentation tool among others. Designed with a user interface and functionality similar to that of Microsoft Office and Lotus SmartSuite, OpenOffice offers a familiar working environment for users. Moreover, it is a free software, making it accessible to a wider audience.

Notably, OpenOffice is capable of reading and writing Microsoft Office files, which ensures compatibility and ease of document exchange. It also boasts features like exporting documents to PDF format with a single click and converting presentations and drawings to Flash. The suite is designed to be inclusive, providing accessibility features for handicapped users, and it supports multiple native languages, enhancing its global usability.

OpenOffice employs an open XML file format for its documents and is compatible with the StarOffice 7[tm] Office Suite, which is based on OpenOffice.org 1.1. Enhancements such as a new macro recorder and support for MySQL databases have been integrated into the suite, further extending its capabilities and appeal to a broad range of users.

Open Office Plugins for Excel

Understanding Add-ins and Functions

The Analysis add-in serves as an illustration of how OpenOffice Calc can utilize additional functions for enhanced compatibility with Excel. These functions, which are similar to the native ones, are created through the add-in interface. The add-in is specifically designed to provide functions for OpenOffice Calc that are compatible with Excel, enabling users to perform tasks in a way that is familiar to those accustomed to Microsoft's spreadsheet software.

Add-in Interface Usage

The add-in interface is a powerful tool that allows for the creation of functions similar to those embedded within Calc itself. Comprehensive guidance is provided for users to complete the explanation of this interface within a few hours, without the need to understand UNO or write C/C++ programs. This approach ensures that users can quickly learn and apply basic techniques to enhance their Calc experience.

UNO and UDK

UNO (Universal Network Objects) is a crucial component in addressing issues within the Analysis add-in, and the UDK (UNO Development Kit) is employed to interact with the OpenOffice.org API. The UDK facilitates the creation of add-ins by providing the necessary tools to work with UNO, which is the only shared library that the Analysis add-in depends on.

Tools Library and Compatibility

While the tools library, which includes the resource manager among other utilities, has been highly beneficial for the Analysis add-in, it is not a mandatory resource for other add-ins. The Analysis add-in itself is versatile, supporting multiple languages and versions of OpenOffice Calc, although it must be built anew for every version. It is evident that OpenOffice aims for functional compatibility with Excel, despite the fact that MS Office plugins are not directly usable with OpenOffice due to the distinct underlying architecture of the two suites.

Add-in Creation and Registration

To create add-ins for OpenOffice Calc, developers use C++ source files and link them to specific libraries including \"CPPUHELPERLIB\", \"CPPULIB\", \"VOSLIB\", and \"SALLIB\". The \"TOOLSLIB\" library remains an optional inclusion. Once the shared library is created, it must be placed in the \"program\" directory, and any accompanying resource files should be copied to the \"program/resource\" directory. Finally, the regcomp tool is utilized to register the new library, making the functions within it accessible to Calc post-registration.
