Incorrect calculation of Round function returns wrong results in some cases. For example, test Microsoft Excel and Spreadsheet results of: ROUND(1.365, 2) to see the discrepancy.

When the worksheet contains fraction numbers with fractional parts > 0.5 and < 0.5 and both these numbers have fraction format applied, the number with fractional part < 0.5 will have incorrect whole part.

When the workbook contains multiple styles (e.g. 50000), the import is extremely slow. MS Excel loads this document instantaneously.

When the values that were copied have formatting both on the cell and on the column, the pasted values get the formatting of the column, instead of that of the cell. The same applies to rows.

One of the options grouped under alignment is Shrink to Fit. Shrink to fit will automatically reduce the font size until text fits in a cell.

When inserting cells a check is performed for data loss. This check should take into account the value property, but should not take into account properties like cell value format and data validation. 

Workaround: clear the values at the end of the worksheet before inserting cells.
worksheet.Cells[1048575, 0, 1048575, 16383].ClearDataValidationRule();

Generating document which consists of merged cells in a row and some values then inserting a row on the top and then exporting the document or setting it to the RadSpreadsheet causes wrong merged cells.

If the generation is done on a workbook which is already set to the RadSpreadsheet everything is OK.

Workaround: The document can be exported and then imported again before the row is inserted.

If a worksheet spans more than one page, you can print row and column headings or labels (also called print titles) on every page to ensure that the data is properly labeled.

Most often, the print area will be defined in the Workbook part like so:
<definedName name="_xlnm.Print_Area" localSheetId="3">Data!$A$1:$L$7</definedName>

Sometimes, however, it can be a function instead:
<definedName name="_xlnm.Print_Area" localSheetId="0">OFFSET('ParametrovĂ˝ List'!$A$1,0,0,INDEX({77,148},PocetStran),34)</definedName>
At the moment, the second option is not supported.

When the scale factor of a document is smaller, the borders don't seem to scale correctly when exported to PDF. They appear much thicker than they would when exported from Excel.

When a worksheet has name that has spaces and a hyperlink to this worksheet is being inserted in Excel, quotes are used to surround the name (ex: 'Sheet 12'!A1) for a valid hyperlink. If quotes are not added, the hyperlink is invalid.
In RadSpreadsheet, it is the opposite: (Sheet 12!A1 is correct, while 'Sheet 12'!A1 is incorrect).
Thus, opening such an exported document from RadSpreadsheet in Excel loads it with incorrect hyperlinks; and importing such an Excel document in RadSpreadsheet loads it with incorrect hyperlinks.

A way to workaround this issue is to modify the hyperlinks on import/export from/to RadSpreadsheet. You can find attached a project demonstrating this approach.

Having cell with custom format string set to "MMM" does not apply correctly. Instead of showing the date in the defined format (for instance "Aug"), what actually is displayed is "MMM".

This will enable printing with the following printing options: 

- Fit Sheet on One Page

- Fit All Columns on One Page

- Fit All Rows on One Page

- Custom automatic scaling


A possible implementation of a similar behavior is to use the PageSize property of WorksheetPageSetup and subtract the corresponding margin values (from the Margins property) from the width to calculate how many columns are fitting in some particular page size with 100% scale factor. 

Available in R2 2018 Official Release version.

When the automatic scaling options FitToColumns and FitToRows are used, the vertical and horizontal breaks, respectively, should be ignored.

Workaround:

Remove the page breaks if the worksheet uses automatic scaling and restore them if necessary:

        public void ExcelToPdf(string path)
        {
            var provider = new XlsxFormatProvider();
            using (Stream input = File.OpenRead(path))
            {
                var workbook = provider.Import(input);

                this.CachePageBreaks(workbook);

                var pdfProvider = new PdfFormatProvider();
                pdfProvider.ExportSettings = new PdfExportSettings(ExportWhat.EntireWorkbook, false);
                using (Stream output = File.Open(@"C:\Users\velcheva\Desktop\26293903-c650-4d28-adee-58a542651f72_exceltopdf\exported.pdf", FileMode.Create))
                {
                    pdfProvider.Export(workbook, output);
                }

                this.RestorePageBreaks(workbook);
            }
        }

        private Dictionary<Worksheet,List<PageBreak>> verticalPageBreaksCache;

        private void CachePageBreaks(Workbook workbook)
        {
            this.verticalPageBreaksCache = new Dictionary<Worksheet, List<PageBreak>>();

            {
                WorksheetPageSetup pageSetup = worksheet.WorksheetPageSetup;

                if (pageSetup.FitToPages)
                {
                    this.verticalPageBreaksCache[worksheet] = new List<PageBreak>(pageSetup.PageBreaks.VerticalPageBreaks);

                        breaksToRemove.AddRange(pageSetup.PageBreaks.VerticalPageBreaks);

                        breaksToRemove.ForEach((br) => pageSetup.PageBreaks.TryRemoveVerticalPageBreak(0, br.Index));
                    }

                    // Record the horizontal page breaks if necessary.
                }
            }
        }

        private void RestorePageBreaks(Workbook workbook)
        {
            foreach (Worksheet worksheet in workbook.Worksheets)
            {
                WorksheetPageSetup pageSetup = worksheet.WorksheetPageSetup;

                if (pageSetup.FitToPages)
                {
                    List<PageBreak> cachedbreaks = this.verticalPageBreaksCache[worksheet];

                    if (pageSetup.FitToPagesWide != 0)
                    {
                        foreach (var pageBreak in cachedbreaks)
                        {
                            pageSetup.PageBreaks.TryInsertVerticalPageBreak(0, pageBreak.Index);
                        }
                    }

                    // Restore the horizontal page breaks if necessary.
                }
            }

The named ranges need to be translated when used in a certain cell just like the data validation rules.

WORKAROUND: When you use RowSelection.Insert() method, for instance, after the row insertion you may iterate all defined names in the document. Parse their RefersTo property and if it is affected by the insertion, delete and recreate the DefinedName in the corresponding NameCollection by updating the RefersTo text value. Sample code for parsing the RefersTo property may be seen in the description of this feedback item:
