Added

  • Added removeComment() method for Worksheet PR #2875

  • Add point size option for scatter charts Issue #2298 PR #2801

  • Basic support for Xlsx reading/writing Chart Sheets PR #2830

    Note that a ChartSheet is still only written as a normal Worksheet containing a single chart, not as an actual ChartSheet.

  • Added Worksheet visibility in Ods Reader PR #2851 and Gnumeric Reader PR #2853

  • Added Worksheet visibility in Ods Writer PR #2850

  • Allow Csv Reader to treat string as contents of file Issue #1285 PR #2792

  • Allow Csv Reader to store null string rather than leave cell empty Issue #2840 PR #2842

  • Provide new Worksheet methods to identify if a row or column is "empty", making allowance for different definitions of "empty":

    • Treat rows/columns containing no cell records as empty (default)
    • Treat cells containing a null value as empty
    • Treat cells containing an empty string as empty

Fixed

1.23.0 - 2022-04-24

Added

  • Ods Writer support for Freeze Pane Issue #2013 PR #2755

  • Ods Writer support for setting column width/row height (including the use of AutoSize) Issue #2346 PR #2753

  • Introduced CellAddress, CellRange, RowRange and ColumnRange value objects that can be used as an alternative to a string value (e.g. 'C5', 'B2:D4', '2:2' or 'B:C') in appropriate contexts.

  • Implementation of the FILTER(), SORT(), SORTBY() and UNIQUE() Lookup/Reference (array) functions.

  • Implementation of the ISREF() Information function.

  • Added support for reading "formatted" numeric values from Csv files; although default behaviour of reading these values as strings is preserved.

    (i.e a value of "12,345.67" can be read as numeric 12345.67, not simply as a string "12,345.67", if the castFormattedNumberToNumeric() setting is enabled.

    This functionality is locale-aware, using the server's locale settings to identify the thousands and decimal separators.

  • Support for two cell anchor drawing of images. #2532 #2674

  • Limited support for Xls Reader to handle Conditional Formatting:

    Ranges and Rules are read, but style is currently limited to font size, weight and color; and to fill style and color.

  • Add ability to suppress Mac line ending check for CSV #2623

  • Initial support for creating and writing Tables (Xlsx Writer only) PR #2671

    See /samples/Table for examples of use.

    Note that PreCalculateFormulas needs to be disabled when saving spreadsheets containing tables with formulae (totals or column formulae).

Changed

  • Gnumeric Reader now loads number formatting for cells.

  • Gnumeric Reader now correctly identifies selected worksheet and selected cells in a worksheet.

  • Some Refactoring of the Ods Reader, moving all formula and address translation from Ods to Excel into a separate class to eliminate code duplication and ensure consistency.

  • Make Boolean Conversion in Csv Reader locale-aware when using the String Value Binder.

    This is determined by the Calculation Engine locale setting.

    (i.e. "Vrai" wil be converted to a boolean true if the Locale is set to fr.)

  • Allow psr/simple-cache 2.x

Deprecated

  • All Excel Function implementations in Calculation\Functions (including the Error functions) have been moved to dedicated classes for groups of related functions. See the docblocks against all the deprecated methods for details of the new methods to call instead. At some point, these old classes will be deleted.

  • Worksheet methods that reference cells "byColumnandRow". All such methods have an equivalent that references the cell by its address (e.g. 'E3' rather than 5, 3).

    These functions now accept either a cell address string ('E3') or an array with columnId and rowId ([5, 3]) or a new CellAddress object as their cellAddress/coordinate argument. This includes the methods:

    • setCellValueByColumnAndRow() use the equivalent setCellValue()
    • setCellValueExplicitByColumnAndRow() use the equivalent setCellValueExplicit()
    • getCellByColumnAndRow() use the equivalent getCell()
    • cellExistsByColumnAndRow() use the equivalent cellExists()
    • getStyleByColumnAndRow() use the equivalent getStyle()
    • setBreakByColumnAndRow() use the equivalent setBreak()
    • mergeCellsByColumnAndRow() use the equivalent mergeCells()
    • unmergeCellsByColumnAndRow() use the equivalent unmergeCells()
    • protectCellsByColumnAndRow() use the equivalent protectCells()
    • unprotectCellsByColumnAndRow() use the equivalent unprotectCells()
    • setAutoFilterByColumnAndRow() use the equivalent setAutoFilter()
    • freezePaneByColumnAndRow() use the equivalent freezePane()
    • getCommentByColumnAndRow() use the equivalent getComment()
    • setSelectedCellByColumnAndRow() use the equivalent setSelectedCells()

    This change provides more consistency in the methods (not every "by cell address" method has an equivalent "byColumnAndRow" method); and the "by cell address" methods often provide more flexibility, such as allowing a range of cells, or referencing them by passing the defined name of a named range as the argument.

Removed

  • Nothing

Fixed

  • Make allowance for the AutoFilter dropdown icon in the first row of an Autofilter range when using Autosize columns. Issue #2413 PR #2754

  • Support for "chained" ranges (e.g. A5:C10:C20:F1) in the Calculation Engine; and also support for using named ranges with the Range operator (e.g. NamedRange1:NamedRange2) Issue #2730 PR #2746

  • Update Conditional Formatting ranges and rule conditions when inserting/deleting rows/columns Issue #2678 PR #2689

  • Allow INDIRECT() to accept row/column ranges as well as cell ranges PR #2687

  • Fix bug when deleting cells with hyperlinks, where the hyperlink was then being "inherited" by whatever cell moved to that cell address.

  • Fix bug in Conditional Formatting in the Xls Writer that resulted in a broken file when there were multiple conditional ranges in a worksheet.

  • Fix Conditional Formatting in the Xls Writer to work with rules that contain string literals, cell references and formulae.

  • Fix for setting Active Sheet to the first loaded worksheet when bookViews element isn't defined Issue #2666 PR #2669

  • Fixed behaviour of XLSX font style vertical align settings PR #2619

  • Resolved formula translations to handle separators (row and column) for array functions as well as for function argument separators; and cleanly handle nesting levels.

    Note that this method is used when translating Excel functions between en_us and other locale languages, as well as when converting formulae between different spreadsheet formats (e.g. Ods to Excel).

    Nor is this a perfect solution, as there may still be issues when function calls have array arguments that themselves contain function calls; but it's still better than the current logic.

  • Fix for escaping double quotes within a formula Issue #1971 PR #2651

  • Change open mode for output from wb+ to wb Issue #2372 PR #2657

  • Use color palette if supplied Issue #2499 PR #2595

  • Xls reader treat drawing offsets as int rather than float PR #2648

  • Handle booleans in conditional styles properly PR #2654

  • Fix for reading files in the root directory of a ZipFile, which should not be prefixed by relative paths ("./") as dirname($filename) does by default.

  • Fix invalid style of cells in empty columns with columnDimensions and rows with rowDimensions in added external sheet. PR #2739

  • Time Interval Formatting Issue #2768 PR #2772

1.22.0 - 2022-02-18

Added

  • Namespacing phase 2 - styles. PR #2471

  • Improved support for passing of array arguments to Excel function implementations to return array results (where appropriate). Issue #2551

    This is the first stage in an ongoing process of adding array support to all appropriate function implementations,

  • Support for the Excel365 Math/Trig SEQUENCE() function PR #2536

  • Support for the Excel365 Math/Trig RANDARRAY() function PR #2540

    Note that the Spill Operator is not yet supported in the Calculation Engine; but this can still be useful for defining array constants.

  • Improved support for Conditional Formatting Rules PR #2491

    • Provide support for a wider range of Conditional Formatting Rules for Xlsx Reader/Writer:

      • Cells Containing (cellIs)
      • Specific Text (containing, notContaining, beginsWith, endsWith)
      • Dates Occurring (all supported timePeriods)
      • Blanks/NoBlanks
      • Errors/NoErrors
      • Duplicates/Unique
      • Expression

    • Provision of CF Wizards (for all the above listed rule types) to help create/modify CF Rules without having to manage all the combinations of types/operators, and the complexities of formula expressions, or the text/timePeriod attributes.

      See documentation for details

    • Full support of the above CF Rules for the Xlsx Reader and Writer; even when the file being loaded has CF rules listed in the <extLst><ext><ConditionalFormattings> element for the worksheet rather than the <ConditionalFormatting> element.

    • Provision of a CellMatcher to identify if rules are matched for a cell, and which matching style will be applied.

    • Improved documentation and examples, covering all supported CF rule types.

    • Add support for one digit decimals (FORMAT_NUMBER_0, FORMAT_PERCENTAGE_0). PR #2525

    • Initial work enabling Excel function implementations for handling arrays as arguments when used in "array formulae" #2562

    • Enable most of the Date/Time functions to accept array arguments #2573

    • Array ready functions - Text, Math/Trig, Statistical, Engineering and Logical #2580

Changed

Deprecated

  • All Excel Function implementations in Calculation\Database, Calculation\DateTime, Calculation\Engineering, Calculation\Financial, Calculation\Logical, Calculation\LookupRef, Calculation\MathTrig, Calculation\Statistical, Calculation\TextData and Calculation\Web have been moved to dedicated classes for individual functions or groups of related functions. See the docblocks against all the deprecated methods for details of the new methods to call instead. At some point, these old classes will be deleted.

Removed

  • Use of nb rather than no as the locale language code for Norsk Bokmål.

Fixed

  • Fixed error in COUPNCD() calculation for end of month Issue #2116 - PR #2119

1.17.1 - 2021-03-01

Added

  • Implementation of the Excel AVERAGEIFS() functions as part of a restructuring of Database functions and Conditional Statistical functions.
  • Support for date values and percentages in query parameters for Database functions, and the IF expressions in functions like COUNTIF() and AVERAGEIF(). #1875
  • Support for booleans, and for wildcard text search in query parameters for Database functions, and the IF expressions in functions like COUNTIF() and AVERAGEIF(). #1876
  • Implemented DataBar for conditional formatting in Xlsx, providing read/write and creation of (type, value, direction, fills, border, axis position, color settings) as DataBar options in Excel. #1754
  • Alignment for ODS Writer #1796
  • Basic implementation of the PERMUTATIONA() Statistical Function

Changed

  • Formula functions that previously called PHP functions directly are now processed through the Excel Functions classes; resolving issues with PHP8 stricter typing. #1789

    The following MathTrig functions are affected: ABS(), ACOS(), ACOSH(), ASIN(), ASINH(), ATAN(), ATANH(), COS(), COSH(), DEGREES() (rad2deg), EXP(), LN() (log), LOG10(), RADIANS() (deg2rad), SIN(), SINH(), SQRT(), TAN(), TANH().

    One TextData function is also affected: REPT() (str_repeat).

  • formatAsDate correctly matches language metadata, reverting c55272e

  • Formulae that previously crashed on sub function call returning excel error value now return said value. The following functions are affected CUMPRINC(), CUMIPMT(), AMORLINC(), AMORDEGRC().

  • Adapt some function error return value to match excel's error. The following functions are affected PPMT(), IPMT().

Deprecated

  • Calling many of the Excel formula functions directly rather than through the Calculation Engine.

    The logic for these Functions is now being moved out of the categorised Database, DateTime, Engineering, Financial, Logical, LookupRef, MathTrig, Statistical, TextData and Web classes into small, dedicated classes for individual functions or related groups of functions.

    This makes the logic in these classes easier to maintain; and will reduce the memory footprint required to execute formulae when calling these functions.

Removed

1.15.0 - 2020-10-11

Added

  • Implemented Page Order for Xlsx and Xls Readers, and provided Page Settings (Orientation, Scale, Horizontal/Vertical Centering, Page Order, Margins) support for Ods, Gnumeric and Xls Readers #1559
  • Implementation of the Excel LOGNORM.DIST(), NORM.S.DIST(), GAMMA() and GAUSS() functions. #1588
  • Named formula implementation, and improved handling of Defined Names generally #1535
    • Defined Names are now case-insensitive
    • Distinction between named ranges and named formulae
    • Correct handling of union and intersection operators in named ranges
    • Correct evaluation of named range operators in calculations
    • fix resolution of relative named range values in the calculation engine; previously all named range values had been treated as absolute.
    • Calculation support for named formulae
    • Support for nested ranges and formulae (named ranges and formulae that reference other named ranges/formulae) in calculations
    • Introduction of a helper to convert address formats between R1C1 and A1 (and the reverse)
    • Proper support for both named ranges and named formulae in all appropriate Readers
      • Xlsx (Previously only simple named ranges were supported)
      • Xls (Previously only simple named ranges were supported)
      • Gnumeric (Previously neither named ranges nor formulae were supported)
      • Ods (Previously neither named ranges nor formulae were supported)
      • Xml (Previously neither named ranges nor formulae were supported)
    • Proper support for named ranges and named formulae in all appropriate Writers
      • Xlsx (Previously only simple named ranges were supported)
      • Xls (Previously neither named ranges nor formulae were supported) - Still not supported, but some parser issues resolved that previously failed to differentiate between a defined name and a function name
      • Ods (Previously neither named ranges nor formulae were supported)
  • Support for PHP 8.0

Changed

  • Improve Coverage for ODS Reader #1545
  • Named formula implementation, and improved handling of Defined Names generally #1535
  • fix resolution of relative named range values in the calculation engine; previously all named range values had been treated as absolute.
  • Drop $this->spreadSheet null check from Xlsx Writer #1646
  • Improving Coverage for Excel2003 XML Reader #1557

Deprecated

  • IMPORTANT NOTE: This Introduces a BC break in the handling of named ranges. Previously, a named range cell reference of B2 would be treated identically to a named range cell reference of $B2 or B$2 or $B$2 because the calculation engine treated then all as absolute references. These changes "fix" that, so the calculation engine now handles relative references in named ranges correctly. This change that resolves previously incorrect behaviour in the calculation may affect users who have dynamically defined named ranges using relative references when they should have used absolute references.

1.8.0 - 2019-07-01

Security Fix (CVE-2019-12331)

  • Detect double-encoded xml in the Security scanner, and reject as suspicious.

  • This change also broadens the scope of the libxml_disable_entity_loader setting when reading XML-based formats, so that it is enabled while the xml is being parsed and not simply while it is loaded. On some versions of PHP, this can cause problems because it is not thread-safe, and can affect other PHP scripts running on the same server. This flag is set to true when instantiating a loader, and back to its original setting when the Reader is no longer in scope, or manually unset.

  • Provide a check to identify whether libxml_disable_entity_loader is thread-safe or not.

    XmlScanner::threadSafeLibxmlDisableEntityLoaderAvailability()

  • Provide an option to disable the libxml_disable_entity_loader call through settings. This is not recommended as it reduces the security of the XML-based readers, and should only be used if you understand the consequences and have no other choice.
