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 related 181318), 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

Code to reproduce 
using (var stream = File.OpenWrite("sample.xlsx"))
using (var workbook = SpreadExporter.CreateWorkbookExporter(SpreadDocumentFormat.Xlsx, stream))
using (var worksheet = workbook.CreateWorksheetExporter("My sheet"))
using (var row = worksheet.CreateRowExporter())
using (var cell = row.CreateCellExporter())
{
      cell.SetValue(string.Format("Error Value: {0} ", Encoding.ASCII.GetString(new byte[] { 8 })));

At this point, CsvWorkbookExporter flushes the data to the underlying stream each time a new data is added. This leads to decreased performance. Ensure the best possible performance by flushing the stream at the end of the content generation.

In addition to the fast document generation, the SpreadStreamProcessing can be adapted to import documents significantly faster than SpreadProcessing.

In some scenarios, the customers need to apply number formatting to the whole column at once. At this point, number formatting can be applied only to the cells.

The implementation should be pretty similar to the SetWidthInPixels() method (or any of the rest) of IColumnExporter.

When setting a date in a cell using SetValue(DateTime), the value should be converted to its numerical representation before adding it to the XML. However, it is currently written as a string. This causes issues when opening the generated file with Google Sheets - the dates are not visible in the file.

A customer also reported that this is causing issues when the file is opened with MS Excel in specific cultures, but we were unable to reproduce that locally.

Workaround: Convert the DateTime value to a number before setting it to the cell:
cell.SetValue(DateTime.Now.Date.ToOADate());

The customers should have the ability to change the symbol used as a delimiter and the symbol used as a quote for a CSV document.

At the moment only the XLSX and CSV formats are supported. It would be a good idea to add the TXT format as well.

Provide a way to measure text on different platforms so the user can pass the cell value and SpreadCellFormat and get the size of the text in pixels. This way we will be able to implement auto-fit to width functionality (AutoFitWidth), at least for the .NET Framework implementation. It will be able to measure the width of all cells in a column and set the value as column width in pixels.
