Introducing Calc

  • Improvements in Calc 4.2:Right-click context menu on bottom left scrollbar arrows to switch sheets (Caolán McNamara)
  • Improvements in Calc 4.3 : Number selected rows and columns in status bar. When selecting cells, the number of selected rows and columns is shown in the status bar. tdf#64290 (Manmeet Singh)
  • Improvements in Calc 4.3: Sheet tab area: when expanding the space available for sheet tabs make better use of that. (Michael Meeks)
  • Improvements in Calc 4.3: Start cell edit with content of cell above: Allow starting of cell edit with the content of the cell above it as its initial content. It is bound to the Ctrl+' (single quote) key by default. (Note: On some locales this keyboard shortcut may conflict with the system default shortcuts. If the default shortcut does not work due to conflict, bind it to a different shortcut). (Kohei Yoshida)
  • Improvements in Calc 4.4:Toolbar improvements. The “Standard” and “Formatting” toolbars were reorganized by removing uncommonly used commands and replacing them with frequent features, in order to reduce the need for users to hunt through menus or customize toolbars. Additional buttons have been added to the toolbars, but are hidden by default and can be enabled by using the toolbar right-click context menu “Customize Toolbar...” option or Tools ▸ Customize.... tdf#85594 (Yousuf Philips)

Keyboard shortcut Ctrl+, to insert date and Ctrl+⇧ Shift+, to insert time is available to various European keyboard layouts. tdf#88027 (Yousuf Philips).The Standard (Single Mode) toolbar was created to be used as an single toolbar alternative to the default double toolbar arrangement and it contains the most used function, insert, and formatting operations. It can be activated by enabling View ▸ Toolbars ▸ Standard (Single Mode) and disabling View ▸ Toolbars ▸ Standard and View ▸ Toolbars ▸ Formatting. tdf#92218 (Yousuf Philips)

RAWSUBTRACT to subtract numbers without canceling out small roundoff errors. tdf#71459 (Eike Rathke (Red Hat, Inc.)) =RAWSUBTRACT(a,b,c) is like =a-b-c, but the - minus operator cancels out small roundoff errors that are due to the fact that not every decimal number can be exactly represented as a binary floating point number and effectively the operation snaps to zero. RAWSUBTRACT uses the IEEE754 operation the platform/compiler provides. For example, =0.3-0.2-0.1 results in 0, whereas =RAWSUBTRACT(0.3,0.2,0.1) results in 2.77555756156289E-17 . Note: Uncheck Tools ▸ Options ▸ Calc ▸ Calculate ▸ Limit decimals for general number format to get this result. This can be used to compare whether a result exactly matches an expected number, i.e. if =RAWSUBTRACT(result,expected) equals 0.0 FORECAST.ETS a set of forecasting functions that use triple and double exponential smoothing and handle seasonal effects. tdf#94635 (Winfried Donkers) . The Holt-Winters algorithms are used. Both Additional and Multiplicative methods are supported for triple exponential smoothing. The set consists of the functions FORECAST.ETS.ADD*, FORECAST.ETS.MULT, FORECAST.ETS.SEASONALITY*, FORECAST.ETS.PI.ADD*, FORECAST.ETS.PI.MULT, FORECAST.ETS.STAT.ADD* and FORECAST.ETS.STAT.MULT. The functions marked with * are interchangeable with MS Excel2016. CONCAT an enhanced version of CONCATENATE, allowing ranges, columns and references as arguments tdf#97831 (Winfried Donkers) . The function is compatible with MS Excel 2016 function CONCAT. TEXTJOIN to concatenate strings with delimeters between the strings. tdf#97831 (Winfried Donkers) . TEXTJOIN allows the same string arguments as CONCAT and has a string argument that will be used as delimiter between the strings to be joined. Also, it is possible to opt for empty cells to be skipped. The function is compatible with MS Excel 2016 function TEXTJOIN. IFS a cascaded IF-function tdf#97831 (Winfried Donkers). IFS works like if A then B else if C then D else if (etc.). The function is compatible with MS Excel 2016 function IFS. SWITCH a multiple choice selection function tdf#97831 (Winfried Donkers) . SWITCH compares one expression with 1 to n possible values and returns the result belonging to the first values that equals expression. The function is compatible with MS Excel 2016 function SWITCH. MINIFS, MAXIFS tdf#97831 (Winfried Donkers) . These statistical functions work like SUMIFS and AVERAGEIFS, but return the minimum respectively maximum value of the resulting range. The functions are compatible with MS Excel 2016 functions MINIFS and MAXIFS.

  • Improvements Calc 5.2:Changed spreadsheet functions. WEEKDAY handles additional type argument values. tdf#100396 (Eike Rathke (Red Hat, Inc.)). For interoperability with other spreadsheet implementations the following new argument values for the second Type parameter are accepted and let WEEKDAY return numbers from 1 to 7: 11: Monday 1 to Sunday 7 , 12: Tuesday 1 to Monday 7 , 13: Wednesday 1 to Tuesday 7 , 14: Thursday 1 to Wednesday 7 , 15: Friday 1 to Thursday 7 , 16: Saturday 1 to Friday 7 , 17: Sunday 1 to Saturday 7 . Previous versions accepted all integer values as Type argument, but any number not 1 or 2 or 3 was handled the same as 3, returning values starting with Monday=0. Now all values not of the set 1,2,3,11,12,13,14,15,16,17 let WEEKDAY return an error.

Simple wildcards as known from other spreadsheet applications can now be used in formula expressions. (Eike Rathke (Red Hat, Inc.)) Wildcards are * (asterisk) any sequence of characters, including empty sequence ? (question mark) any character, exactly one ~ (tilde) escapes the special meaning of the following asterisk, question mark or tilde See also tdf#72196 and related section in ODF 1.2 table:use-wildcards and OpenFormula Host-Defined Behaviors. Wildcards are supported in all functions that already supported regular expressions, which are: all database functions DAVERAGE, DCOUNT, DCOUNTA, DGET, DMAX, DMIN, DPRODUCT, DSTDEV, DSTDEVP, DSUM, DVAR and DVARP; the functions COUNTIF, COUNTIFS, HLOOKUP, LOOKUP, MATCH, VLOOKUP, SUMIF, SUMIFS, AVERAGEIF, AVERAGEIFS and SEARCH. Accordingly the setting was changed, under Menu ▸ Tools ▸ Options ▸ Calc ▸ Calculate there is now a Enable wildcards in formulas radio button grouped with Enable regular expressions in formulas and No wildcards or regular expressions in formulas. When reading ODF spreadsheet documents with table:use-wildcards enabled or importing Microsoft Excel spreadsheet documents the option is set to wildcards enabled.

  • Improvements Calc 5.2 : Using named expressions and ranges with sheet-local scope on other sheets. It is now possible to use a defined name with a scope local to a sheet in a formula on any other sheet. tdf#96915 (Eike Rathke (Red Hat, Inc.)). For example, a named range LocalName defined with scope Sheet1 can be used in a formula on Sheet2 as =SUM(Sheet1.LocalName), usual sheet name constraints for references apply, e.g. if the sheet name contains a blank it has to be enclosed in single quotes, as in =SUM('Other Sheet'.LocalName)
  • Improvements Calc 5.2 : Copying named expressions and ranges while copying sheets. While copying entire sheets, named expressions and ranges that point to the copied sheet and are used by any formula cell that is copied along with the sheet are copied to new sheet-local scoped names. tdf#75372 (Eike Rathke (Red Hat, Inc.))
  • Improvements Calc 5.2 : Number Format. Date/Time Formats (Laurent BP). as minute and month have same code M, disambiguation have been improved tdf#95339 tdf#101147
  • Improvements Calc 5.3  : Arrows Toolbox. New drawing tools were added (that were previously available only in Draw and Impress). tdf#101390 (Gülşah Köse). Changed spreadsheet functions: The UI name of EFFECTIVE was changed to EFFECT to be the same as in other spreadsheet applications. tdf#100641 (Eike Rathke (Red Hat, Inc.)). Compatibility with ODF 1.2 : ISOWEEKNUM and WEEKNUM_OOO. Releases prior to 5.1 saved WEEKNUM wrongly as ISOWEEKNUM to ODF. Release 5.3 resolves the interim solution introduced with release 5.1 (see ReleaseNotes/5.1#Compatibility_with_ODF_1.2). (Eike Rathke (Red Hat, Inc.)) . When importing ISOWEEKNUM, if the call uses one parameter it is kept as the correct ISOWEEKNUM. If the call uses two parameters it is determined if the second argument mode is a literal numeric value unequal to 1 in which case it is mapped to ISOWEEKNUM with one argument, as the old WEEKNUM function implemented exactly that for those modes. If the second argument is something different, i.e. a numeric value 1 or an expression, the call is mapped to the WEEKNUM_OOO compatibility function introduced in LibreOffice 5.1. WEEKNUM_OOO is now saved as ORG.LIBREOFFICE.WEEKNUM_OOO which releases 5.1 and 5.2 can read. Functions ( Insert ▸ Function ) can now be searched from the available list tdf#67974. Calc now supports scrolling through the Scroll key tdf#46200.
  • Improvements Calc 5.3  : Option settings. In new installations the default setting for new documents is now Enable wildcards in formulas instead of regular expressions. tdf#88581 (Eike Rathke (Red Hat, Inc.)) . This is for better interoperability with other spreadsheet applications and a better experience for users who are not familiar with regular expressions. Wildcards are more widespread and the large set of regular expression metacharacters often makes queries too complicated for casual users. See also ReleaseNotes 5.2 for wildcards.
  • Improvements Calc 5.4  : Priority of conditional formatting rules can be changed with new up/down buttons. tdf#74074 (Manfred Blume, CIB)
  • Improvements Clac 5.4: While building formulas, when selecting a cell or range on another sheet with the pointer, absolute sheet references are now created instead of relative. tdf#90799 (Eike Rathke (Red Hat, Inc.))
  • Improvements Calc 5.4: New spreadsheet functions. New function ROUNDSIG to round a value at a number of significant digits. tdf#105931 (Winfried Donkers) . Changed spreadsheet functions: The semantics of the COUNTIF, SUMIF and AVERAGEIF Criteria argument has been changed. The equals empty "=" and not-equals not-empty "<>X" criteria now also match empty cells of a given range like they are evaluated in other spreadsheet applications.

New ODFF1.2 compliant functions SEARCHB, FINDB and REPLACEB added (commit1, commit2, commit3). (Winfried Donkers) FINDB returns the starting position of a given text, using byte positions. FINDB is case sensitive. SEARCHB returns the starting position of a given text, using byte positions. REPLACEB returns text where an old text is replaced with a new text, using byte positions.

Using Pivot Tables.

  • Improvements 4.3 Calc : Pivot Table layout improvement. "Data" field is now on columns by default, and can be moved to rows if needed. This makes it much faster to generate useful pivot tables from large data sources. tdf#77927 (Tomaž Vajngerl)
  • Improvements Calc 5.0: Item labels in Pivot Tables can be repeated now. This is optional. When you create a pivot table, double-click on the desired field in the list "Row fields". In the dialog box "Data Field", then click button "Options". In the next dialog box, select "Repeat item labels". Click OK. tdf#87972 (Deena Francis) Screenshot.
  • Improvements Calc 5.3 : Pivot tables.Median is added to functions available in pivot tables, useful for data fields and for row/column fields (subtotals) tdf#61700 (Tamás Zolnai) Only ODS file format is supported to save/load such pivot tables.

Pivot table interop fixes (Mike Kaganski (Collabora), Tamás Zolnai (Collabora), Bartosz Kosiorek)

  • Release notes 4.4 Firefox Themes : Firefox Themes. New browser for Firefox themes with search and preview. (Rachit Gupta, 2014)
  • Release Notes 4.4 Firefox Themes : Firefox themes now apply also to bottom toolbars. tdf#59299 (Michael Jaumann, )
  • Release Notes 4.4 Icon improvements : Icon improvements. New and improved icons have been added to the Tango, Sifr, and Oxygen icon themes. tdf#75256 tdf#75359 (Mirek Mazel; Yousuf Philips; Matthias Freund; Alexander Wilms; and Adolfo Jayme Barrientos) . Large icons are shown by default on Windows, as they are on Linux and macOS. tdf#82309 (Jan Holešovský, Collabora; and Yousuf Philips)
  • Improvements Calc 6.0  : Added support for user icon themes via extension manager tdf#110742 (Caolán McNamara)
  • Improvements Calc 6.0  : Customize. It is now easier than ever to customize LibreOffice UI based on your needs, thanks to improved user experience and accessibility of the newly reworked Customize dialog (Tools ▸ Customize...). tdf#88896 (Muhammet Kara (Pardus), GSoC 2017; Katarína Behrens (CIB); Heiko Tietze; Yousuf Philips) . The Menus, Toolbars, and Context Menus tabs have been revamped to provide a modern and intuitive design which is highly accessible and user friendly. With the well-established two-pane design of the revamped dialog, it is possible to customize toolbars, menus, and context menus following a nice work-flow, without leaving the dialog. A search box has also been introduced to filter the functions which can be assigned to UI elements, so you can easily and quickly find exactly what you are looking for without navigating through a list of too many categories and functions. The Keyboard tab has also got the new search box. tdf#63966 . Last but not least improvement is the cleaned-up and re-factored code under the hood, which eliminates some bugs of the past and prepares for the features of the future.
  • Change Calc 6.0  : Configuration Memory. Memory configuration page has been removed from Options dialog tdf#110448 (Mike Kaganski, Collabora).

Now extension installation and removal via the Extension Manager dialog (Tools ▸ Extension Manager...) can be dynamically enabled/disabled from the expert configurations (Tools ▸ Options ▸ Advanced ▸ Open Expert Configurations). tdf#36019 (Muhammet Kara, Pardus; Heiko Tietze) . This also affects the installation by double-clicking the extension file in the file manager, but doesn't affect the unopkg commands. When ExtensionSecurity::DisableExtensionRemoval is set in expert configurations, context menu entry of 'remove' for installed extensions is also disabled along with the "Remove" button on the dialog.

Calc's cell storage structure has been completely re-written, to store contiguous cell values in contiguous memory region to improve locality of reference as well as the cost of storage. The new structure also enables hardware accelerated parallel calculations of a large number of cells. (Kohei Yoshida) Calc core now shares all string instances stored in cells and several other places in order to significantly speed up both case sensitive and case insensitive string comparisons, and also to allow string equality check in OpenCL-based formula interpreter. This change also speeds up execution of several cell functions (such as VLOOKUP) that perform a large number of string equality comparisons. Filtering of rows via AutoFilter, Standard Filter, and Advanced Filter should run faster thanks to shared strings. (Kohei Yoshida) Vertically adjacent formula cells containing identical formula token set now share their formula token array instance. This can drastically reduce run-time memory usage of Calc, and also speeds up automatic reference updates when moving cells. (Kohei Yoshida) XLSX import filter has been re-worked to achieve significant boost on the import performance on XLSX documents. The speed up was achieved by moving much of the temporary string allocations and deallocations that occur during the XML parsing phase to a separate thread, and also by re-working the handler logic on the Calc side to reduce inefficiencies, especially with regard to importing of formula cells. (Kohei Yoshida, Michael Meeks, Matúš Kukan) Added an experimental multi-threaded import for XLSX documents. When the experimental features are enabled, Calc tries to import XLSX documents using multiple threads, to import multiple sheets concurrently. (Kohei Yoshida, Michael Meeks) Significant speed up on the export of ODS document that contains a large number of rich-text cells. Refer to this blog post for more details. (Kohei Yoshida) Cell note storage has been re-worked to use multi_type_vector, in order to improve the performance of import and export of documents containing large number of cell comments. (Laurent Godard) Improved performance of VLOOKUP function with use of external references. (Pierre-Eric Pelloux-Prayer) Improved performance of SUM, COUNT, and SUMIFS function. (Kohei Yoshida)

  • Improvements Calc 5.0 : Table structured references. tdf#85063 (Eike Rathke) Table structured references in spreadsheet formula expressions are imported from OOXML spreadsheet documents. Usable with defined database ranges, which OOXML tables (content of elements) are imported to. The following restrictions apply: The column names must be present as cell content in the table's header row; column-header-less tables are not supported. Saving to ODF or OOXML, structured references are not written, but transformed to A1 style reference notation instead. The references continue to work, but the table context is lost on export. Saving to OOXML, the defined database ranges are not exported as elements. Saving to binary .xls (Microsoft Excel 97-2003 Format), formulas using table structured references are lost.
    • Improvements Calc 5.0 : Formula engine. New spreadsheet functions. Changes related to FLOOR and CEILING spreadsheet functions. tdf#69552 (Winfried Donkers and Eike Rathke) The second parameter of FLOOR and CEILING is now optional, as defined by OpenFormula (ODFF). Additional FLOOR.XCL and CEILING.XCL functions were introduced that expect only two parameters and both parameters have to be specified. When importing Microsoft Excel documents, their old FLOOR and CEILING functions are imported as FLOOR.XCL and CEILING.XCL.New functions FLOOR.MATH and CEILING.MATH were added for Microsoft Excel interoperability. tdf#87342 (Winfried Donkers) Exporting to Microsoft Excel file formats, Calc FLOOR and CEILING are written as Excel FLOOR.MATH and CEILING.MATH, and Calc FLOOR.XCL and CEILING.XCL are written as Excel FLOOR and CEILING .

    • Improvements Calc 5.2 : Classification according to TSCP-standards Improvements. In Writer, Calc and Impress there is the tool bar Classification that allows choosing the classification level. Choosing the classification level will result in an info bar, and in Writer (depending on the level) also in a watermark and a field in the header and footer. All showing the level of classification. Of course the classification is stored in document properties. In the current implementation there are three categories to choose from. The first one (named "Intelectual property" according to TSCP_BAILSv1) sets the header/footer and watermark (for certain levels). This is likely to be modfied in future versions. Look for Classification Bar in the local or on line Help [1]. Also see this blog entry. (Miklos Vajna, Collabora)

    The custom palette is newly added, which allows colors to be added directly in the area style dialog. Custom palette makes the manipulation of factory settings via Tools ▸ Options ▸ LibreOffice ▸ Colors obsolete ‒ and hence we deleted this option. The palettes gallery, web, cmyk, and scribus were removed because of the non-standard and rather arbitrary collections with inappropriate names Tango and html palettes received minor updates for labels and arrangement of colors . The standard palette was also refreshed. The first row now starts with 12 shades of gray followed by 12 basic colors from the color wheel. The next rows are variations of these basic colors in respect to saturation and luminance by 66%, 50%, and 25%. The final 12×8 arrangement fits perfectly into our color picker grid . The palette breeze has been added to the default set. It comprises all values known from the KDE human interface guidelines as an alternative to tango . Completely new is the tonal palette. It aims to provide a set of colors with the same luminance respective color contrast . The palette freecolour-hlc based on the color model has been added. Its purpose is to provide a cross-media safe set of colors targeting expert publishers .
