Exception when rounding a decimal value in a formula with a lot of precision numbers

The content of some rows which contain new lines can be clipped when a fixed-width column is wrapped.

This can be observed in the following images.

Before the export:

After the export:

The formula when adding a number to date is not calculated correctly. 

The vertical grid lines are not visible in a scatter chart. The grid lines are visible when opened in Excel.

 

Formula evaluation causes an endless loop when importing a specific file

If some notes exist below the inserted/removed cells, the notes need to be moved as well along with the rest of the cells. Currently, after insert/remove, the notes are still associated with the original cell index thus are in the wrong cells.

Indirect function cannot get named range by name as string or cell value.

A feature in Excel allows adding ActiveX controls in the Worksheets. You can insert the ActiveX controls from the Developer ribbon tab from the insert button. As it is a missing feature it is not imported and thus removed from the document on export.

The Spilled range operator (#) is responsible for selecting the whole range of values used after a cell reference.

The error is with a message "Index and count must refer to a location within the string (Parameter 'count')" and is thrown inside the FormatHelper.FindAllOccurrences method.

DataTableFormatProvider: One should be able to set the AllowDBNull property of each column.

Applying conditional formatting to different worksheets and exporting the file to XLSX results in a file with conditional formatting on the active sheet only. The conditional formatting on the rest of the worksheets is lost. 

The pie chart is not rendered correctly and is not converted to pdf as expected.

The format applied to the first value of the range of the chart determines the format of the value (vertical) axis. If the format of this value is changed, the model attempts to set a new format to the axis. If the chart does not support axes, the value of its PrimaryAxes property is null, which causes NullReferenceException.

Currently, indexed colors are imported only regarding the default color palette. Instead, when the entire palette is predefined using a construct like: 

  <colors>
    <indexedColors>
      <rgbColor rgb="00000000"/>
      ...

in styles.xml part, the indexed should be changed with the provided ones. As this feature is not implemented, such colors are changed during the import.

Chart not visible when file has OneCellAnchor xaml element.

Add API that allows one to manipulate the macros inside a Workbook.

SpreadProcessing: Upon export, sheet reference in formulas such as VLOOKUP is lost when using whole row/column references.
For example the formula
=VLOOKUP("test",Sheet1!A:C,1,0) is exported as

=VLOOKUP("test",A:C,1,0)

When a file is imported that has an unsupported theme color type, the resulting ThemableColor is null. This results in a NullReferenceException on export.

If a cell has a style set (e.g. Bad) and no fill set on the same cell, after import and export, the no fill setting will be lost and the cell will be shown with its cell style instead.
