KOffice was afree and open sourceoffice andgraphics suite developed byKDE forUnix-like andWindows systems. KOffice contains aword processor (KWord), aspreadsheet (KSpread), apresentation program (KPresenter), and a number ofother components that varied over the course of its development.
KOffice was superseded byCalligra Suite inKDE. The KDE3 version is maintained by theTrinity Desktop project.
After development began in 1997, two major stable releases of KOffice were published: Version 1.0 in 2000 and 2.0 in 2009. Following internal conflicts, the majority of KOffice developerssplit off in 2010 – resulting in the creation ofCalligra Suite. Two years later, in September 2012, the KOffice.org website went offline.[9] It now redirects to Calligra.org.

Initial work on KOffice development began in 1997, by Reginald Stadlbauer[16][17] withKPresenter, followed byKWord[18] in 1998.
In 1999, KOffice was cited in testimony in theUnited States v. Microsoft antitrust trial by then-Microsoft executivePaul Maritz as evidence of competition in the operating system and office suite arena.[19]
The first official release of the KOffice suite was on 23 October 2000, when it was released as part ofK Desktop Environment 2.0.[2] Version 1.1 followed in 2001,[20] 1.2 in 2002,[21] 1.3 in 2004,[22] 1.4 in 2005,[23] and 1.5[24] and 1.6 both in 2006.[25]
KOffice underwent a major transition as part of the release ofKDE Software Compilation 4 (SC4). Coinciding with the work on SC4, the KOffice team prepared a major new release – KOffice 2.0 – which used the newKDE Platform 4 libraries. Although version 2.0 was released in 2009, the release was labeled as a “platform release” which was recommended only for testers and developers, rather than production use, since the release was missing key features and applications from the previous stable release series –Kexi,Kivio, andKugar were not included.[26]
This continued with version 2.1 in November, 2009. Regular end-users requiring a stable environment were still recommended by developers to use the stable 1.6 release series.[27] This version was also ported toHaiku[28] but the port was later not updated for newer KOffice versions.
In May 2010, version 2.2.0 was released and brought an unprecedented number of new features and bugfixes.Kexi was integrated again.Kivio was not migrated. A new framework for effects on shapes and a new import filters for the MicrosoftOffice Open XML formats used in MS Office 2007 and later was added.[29]
In mid-2010, following disagreements between KWord maintainer Thomas Zander and the other core developers,[30][31][32] the KOffice community split into two separate communities, KOffice andCalligra. Following arbitration with the community members several applications were renamed by both communities.[33] KOfficeforked the KSpread spreadsheet utility toKCells, also the KPresenter presentation tool toKOffice Showcase, and theKarbon14 drawing tool toKOffice Artwork.
The community split coincided with the move from KDE'sSubversion repository togit. TheKrita painting application, theKexi database manager, and dedicated mobile platformGUI files were not migrated into the KOffice git repository.[34][35][36]
KOffice 2.3, released 31 December 2010,[37] along with subsequent bugfix releases (2.3.1–2.3.3[38]) was still a collaborative effort of both the KOffice and Calligra development teams.[39] Kivio was still not integrated[40]
Beginning with KOffice 2.4 the developers aimed to release new KOffice versions every six months in sync withSC4 releases[41] but KOffice had seen no development activity since mid-March 2012.[42] As of September 2013, Calligra has released 2.4 and 2.5 and 2.6 and 2.7. After two minor commits in August 2012[43] the koffice.org website was replaced by a placeholder in early September 2012.[9] On 22 October 2012 KDE removed KOffice from their Quality Website Tools.[44]
As of 2014[update] KOffice was declared unmaintained by KDE.[45][46]
The last formally released version of KOffice included the following components:
 | KWord | Aword processor withstyle sheets and frame-support forDTP-style editing of complexlayouts. |
 | KSpread | Aspreadsheet application with multiple sheet support, templates and more than 100mathematicalformulae. |
 | KPresenter | Apresentation program with image and effect support. |
 | Kexi | An integrated data management application, designed as aMicrosoft Access orFileMaker competitor. It can be used for designing and implementingdatabases, inserting and processing data and performing queries. It has limited compatibility with the MS Access file format. |
 | Karbon14 | Avector drawing application with a variety of drawing and editing tools – formerly known as Kontour and KIllustrator.[2] |
 | Krita | Adigital painting program, with someimage processing features – formerly known as Krayon and KImageshop. |
 | KChart | Integratedreport andchart generator. |
 | KFormula | An integrated mathematicalformula editor. |
 | KPlato | Aproject management application that can createGantt-style charts. |
KOffice applications were developed usingQt andKDE Platform. All its components are released underfree software licenses and useOpenDocument as their native file format when possible. KOffice was released separately fromKDE SC 4 and can be downloaded from KDE's FTP server.
KOffice 2 underwent a large overhaul to use theFlake system of components andPigment color system, as much as possible within applications. KOffice developers planned to share as much infrastructure as possible between applications to reduce bugs and improve the user experience.[47] They also wanted to create an OpenDocument library for use in other KDE applications that will allow developers to easily add support for reading and outputting OpenDocument files to their applications.[48] Automating tasks and extending the suite with custom functionality can be done withD-Bus or with scripting languages likePython,Ruby, andJavaScript.[49]
This version of KOffice is translated to no less than 27 languages.
