Calligra Sheets (formerly KSpread and Calligra Tables) is a free software spreadsheet application that is part of Calligra Suite, an integrated graphic art and office suite developed by KDE.
Among Sheets’ features are multiple sheets per document, assorted formatting possibilities, support for more than 300 built-in functions, templates, chart, spell-check, hyperlinks, data sorting and scripting with Python, Ruby and JavaScript.
Sheets’ native file format has been OpenDocument since version two and previously used its own XML format, compressed with ZIP. Sheets also has the ability to import several spreadsheet formats, including XLS (Microsoft Excel), Applix Spreadsheet, Quattro Pro, CSV, dBase, Gnumeric, SXC (OpenOffice.org XML), Kexi and TXT. It supports export of OpenDocument Spreadsheet, SXC, Tables document, CSV, HTML, Gnumeric, TeX and TXT. Sheets does not support export of XLS.[1]
KChart is the charting tool of Calligra Suite. The plug-in is relatively simple compared to other office applications such as OpenOffice, being designed for small datasets, and using only the most common 5–6 types of chart (histograms, pie charts, line charts, etc.)

Calligra Sheets (formerly KSpread and Calligra Tables) is a free software spreadsheet application that is part of Calligra Suite, an integrated graphic art and office suite developed by KDE.
Calligra Suite is a graphic art and office suite by KDE. It is available for desktop PCs, tablet computers, and smartphones. It contains applications for word processing, spreadsheets, presentation, databases, vector graphics, and digital painting. Calligra uses the OpenDocument format as its default file format for most applications and can import other formats, such as Microsoft Office formats. Calligra relies on KDE technology and is often used in combination with KDE Plasma Workspaces.
A spreadsheet is a computer application for computation, organization, analysis and storage of data in tabular form. Spreadsheets were developed as computerized analogs of paper accounting worksheets. The program operates on data entered in cells of a table. Each cell may contain either numeric or text data, or the results of formulas that automatically calculate and display a value based on the contents of other cells. The term spreadsheet may also refer to one such electronic document. In modern spreadsheet applications, several spreadsheets, often known as "worksheets" or simply "sheets", are gathered together to form a "workbook". A workbook is physically represented by a file containing all the data for the book, the sheets, and the cells with the sheets. Worksheets are normally represented by tabs that flip between pages, each one containing one of the sheets, although Numbers changes this model significantly. Cells in a multi-sheet book add the sheet name to their reference, for instance, "Sheet 1!C10". Some systems extend this syntax to allow cell references to different workbooks. Spreadsheet users can adjust any stored value and observe the effects on calculated values. This makes the spreadsheet useful for "what-if" analysis since many cases can be rapidly investigated without manual recalculation. Modern spreadsheet software can have multiple interacting sheets and can display data either as text and numerals or in graphical form. Besides performing basic arithmetic and mathematical functions, modern spreadsheets provide built-in functions for common financial accountancy and statistical operations. Such calculations as net present value, standard deviation, or regression analysis can be applied to tabular data with a pre-programmed function in a formula. Spreadsheet programs also provide conditional expressions, functions to convert between text and numbers, and functions that operate on strings of text. Spreadsheets have replaced paper-based systems throughout the business world. Although they were first developed for accounting or bookkeeping tasks, they now are used extensively in any context where tabular lists are built, sorted, and shared.
KOffice was a free and open source office and graphics suite developed by KDE for Unix-like and Windows systems. KOffice contains a word processor (KWord), a spreadsheet (KSpread), a presentation program (KPresenter), and a number of other components that varied over the course of its development. KOffice was superseded by Calligra Suite in KDE. The KDE3 version is maintained by the Trinity 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 developers split off in 2010 – resulting in the creation of Calligra Suite. Two years later, in September 2012, the KOffice.org website went offline. It now redirects to Calligra.org.
Before the 1921 destruction of Tulsa’s Greenwood District, Black residents had created a remarkable center of business and community life. The district included stores, professional offices, entertainment venues and homes owned by Black citizens. Understanding Greenwood means learning what was built—not only what was burned.
