ArgumentException with clarification similar to  "'\u001f', hexadecimal value 0x1F, is an invalid character." is thrown when trying to export document containing characters which are not supported in XML document - such as some control characters like 0x00, 0x1F, 0x1B, etc. Such characters are described in the XML specification here: https://www.w3.org/TR/xml/#charsets.

Although the escaped strings are not supported (see  https://feedback.telerik.com/Project/184/Feedback/Details/190228 ), the library could prevent the exception and export the document successfully by skipping such characters.

Workaround: remove such characters before the export. Check the following StackOverflow answer for some ideas on code for replacing the characters: http://stackoverflow.com/a/14323524/259206

Fix available in R3 2018 SP1 release.

The cell contains the following data in OOXML:

<f>SUM(1,2,3)</f> - The formula
<v>6</v> - the calculated value

The formula value is imported, but the calculated value is skipped. The feature will be useful if Manual calculation option is supported: https://feedback.telerik.com/Project/184/Feedback/Details/191275-spreadsheet-add-support-for-different-calculation-options-automatic-or-manual

Add support for manual calculation option, which allows not to recalculate all the formulas on value change, but on manual request. 

MS Excel supports this feature in Formulas -> Calculation -> Calculation Options, with the following options: Automatic, Automatic Except for Data Tables, Manual.

CellSelection.SetValue method causes memory leak of CellReferenceRangeExpression objects in some cases when cell value is referenced by formulas. The memory leak is small, but the remaining CellReferenceRangeExpression continue to listen to some events, causing performance issues when their number become large - the time to set the value increases with each set.

The API should be able to provide a way to move the X-axis away from the 0 value on the Y-axis or to the bottom of the chart when there are negative Y-axis values.

In Excel this can be achieved by right click on the axis, then from the context menu select "Format Axis".  Go to the "Labels" group and then in the "Label position" field select the desired value.
