Korrekturen
  • When recalculating spilling dynamic array formulas EPPlus did not always follow new dependent addresses.
  • The SUMIFS/COUNTIFS/AVERAGEIFS functions now evaluate date string literal criteria correctly.

Funktionen
  • Updated System.Security.Cryptography.Xml for .NET 9 and 10 to address a security vulnerability (CVE-2026-26171 and CVE-2026-33116).

  • ExcelRange.LoadFromCollection: DisplayAttribute.Name was used directly instead of DisplayAttribute.GetName(), causing resource keys to appear as column headers instead of localized values when ResourceType was set.
  • ExcelRange.LoadFromCollection: EpplusTableColumnAttribute.Order was ignored when DisplayAttribute was also present.
  • Fixed various issues with the LAMBDA function and variable expressions.
  • Fixed an issue with the VSTACK and HSTACK functions when the argument is a single-cell range.

Korrekturen
  • Fixed issue where updated .NET 8 references incorrectly update to 9.x to 8.x in EPPlus 8.5.2.
EPPlus v8.5.130. März 2026
Korrekturen
  • Negation of numeric string values now returns the negated number instead of a #VALUE! error in the formula calculation.
  • 'ExcelPackage.Configure' now sets 'IConfiguration' for license info.
  • The WEEKDAY function now handles optional return-types 12-17 correctly.
  • Inserting rows or columns when a named range is on the maximum row is now handled correctly. Absolute referenced defined names become #REF! when pushed outside the maximum.
  • NUMBERVALUE function now parses decimal and group separators for numbers correctly.

EPPlus v8.5.06. März 2026
Funktionen
  • Added 'CancellationToken' to Calculate.

  • Improved performance for SUMIFS, AVERAGEIFS, COUNTIFS.
  • Improved performance for formula calculation with full column references (e.g. A:A, $B:$B).
  • Breaking Changes:
    • Setting dataLabelPosition.Top on BarCharts corrupted the Excel file when saved. Trying to set this now throws an error instead.
    • NumberFormatToTextArgs.NumberFormat now returns the interface IExcelNumberFormat rather than the ExcelNumberFormatXml class. All public variables remain the same and it can be safely cast to 'ExcelNumberFormatXml' as long as 'Package.Workbook.NumberFormatToTextHandler' is null.

  • Fixed several formatting issues when reading and writing tables with checkboxes in them.
  • Fixed several issues when using a custom ExcelPackage.Workbook.NumberFormatToTextHandler.

  • Fixed culture-specific DateTime in PowerQuery metadata.
  • Calculated field computation in pivot tables did not work correctly in some cases.
  • Copying a Connection shape from one workbook to another caused an unhandled exception.

  • Fixed a performance issue when using FollowDependencyChain set to false in the Calculate method. With this option, EPPlus no longer calculates dependent cells or dynamic array formula spills.
  • Fixed an issue where the ExcelPowerQueryMetadataItem class parsed dates using the supplied culture instead of the invariant culture, which could cause an unhandled exception.
  • Fixed an issue where a workbook could become corrupt when EPPlus adjusted the XML ignorable namespace list.
  • Fixed an unhandled exception that occurred when saving a workbook containing a customXml property file without a schemaRefs file.
EPPlus v8.4.112. Jan. 2026

    • Changing cell dependencies were not taken into account when recalculating dirty cells from dynamic array formulas.
    • Clearing dynamic array formulas that reduced in size did not work correctly.
    • Cells containing formulas with the INDIRECT function are now always treated as dynamic.
  • Invalid UTF-16 surrogate sequences in comment text are now sanitized before XML generation to prevent 'XmlException'.

  • The FILTER function always returned the third parameter if it contained an error value (for example, #VALUE).
  • The FACT function returned (n-1) instead of n.
  • Formula inline arrays did not correctly convert scientific notation (for example, 1.0E-305) to numbers.
  • Defined names could use the wrong scope when a name existed in both worksheet and workbook scope and a formula was calculated using the 'Calculate(formula)' method.
  • Using the ^ operator on non-numeric values returned 0 instead of #VALUE.
  • Inserting columns into an empty worksheet throw an 'ArgumentException' when inserting more than 8 columns.
  • GROWTH and TREND did not handle a single-value newX parameter correctly.
