Hyperformula Versions Save

Added

• Added method getNamedExpressionsFromFormula to extract named expressions from formulas. #1365
• Added context config option for passing data to custom functions. #1396

Changed

• Removed unorm dependency. #1370

Fixed

• Fixed an issue where operating on ranges of incompatible sizes resulted in a runtime exception. #1267
• Fixed an issue where the simpleCellAddressFromString() method was crashing when called with a non-ASCII character in an unquoted sheet name. #1312
• Fixed an issue where adding a row to a very large spreadsheet resulted in the Maximum call stack size exceeded error. #1332
• Fixed an issue where using a column-range reference to an empty sheet as a function argument resulted in the Incorrect array size error. #1147
• Fixed an issue where the SUBSTITUTE function wasn't working correctly with regex special characters. #1289
• Fixed a typo in the JSDoc comment of the HyperFormula class. #1323

Added

• Exported the EmptyValue symbol as a public API. This allows custom functions to handle empty cell values. #1232

Changed

• Improved the efficiency of the default date/time parsing methods. #876
• Improved the efficiency of the operations on the dependency graph. #876

Fixed

• Fixed a bug where neighboring exported changes of an array formula were missing. #1291
• Fixed a typo in the source code of the MatrixPlugin. #1306

Added

• Added a new function: ADDRESS. #1221
• Added a new function: HYPERLINK. #1215
• Added a new function: IFS. #1157

Changed

• Optimized the updateConfig() method to rebuild HyperFormula only when the new configuration is different from the old one. #1251

Fixed

• Fixed the SEARCH function to be case-insensitive regardless of HyperFormula's configuration. #1225

Added

• Exported the CellError class as a public API. #1232
• Exported the SimpleRangeValue class as a public API. #1178

Fixed

• Fixed an EmptyCellVertex data integrity issue between the AddressMapping and DependencyGraph objects. #1188
• Fixed a build issue with M1- and M2-chip MacBooks. #1166
• Fixed an issue where the order of items returned by removeColumns() depended on the address mapping policy. #1205

Fixed

• Fixed an issue where expression names were not allowed to start with a cell reference. #1058
• Fixed an issue where expression names were allowed to start with R1C1-notation references. For better compatibility with other spreadsheet software, strings such as R4C5, RC1000, R1C or RC can't be used in expression names anymore. #1058
• Fixed an issue where using reversed ranges with absolute addressing could cause the Incorrect array size error. #1106
• Fixed an issue where removing a sheet (removeSheet()) without clearing it (clearSheet()) could cause an error. #1121

Added

• Exported the ArraySize class as a public API. #843
• Renamed an internal interface from ArgumentTypes to FunctionArgumentType, and exported it as a public API. #1108
• Exported ImplementedFunctions and FunctionMetadata as public APIs. #1108

Added

• Added an American English (enUS) language pack. It's a convenience alias: it contains the same translations as the existing British English (enGB) language pack. #1025

Fixed

• Fixed functions VLOOKUP and HLOOKUP to handle duplicates in the way specified by the OpenDocument standard. #1072
• Fixed the MATCH function to handle descending ranges in the way specified by the OpenDocument standard. #1063

Added

• Added two new functions: MAXIFS and MINIFS. #1049

Changed

• Changed the rounding strategy of the default time-parsing function to be independent of the timeFormats configuration option. Now, time values are always rounded to the nearest millisecond (0.001 s). #953

Fixed

• Fixed a rounding issue that caused the TEXT function to incorrectly convert dates and times to strings. #1043
• Fixed an issue where functions SUMIF, SUMIFS, COUNTIF, COUNTIFS, and AVERAGEIF incorrectly handled complex numeric values. #951

Removed

• Removed all polyfills from the CommonJS build and the ES modules build. In the UMD build, kept only the polyfills required by the supported browsers. #1011
