Excel cell inline text formatting

With GemBox.Spreadsheet you can apply font formatting for the whole cell's text (see Styles and Formatting) or for the individual characters and words.

You can specify the size, color, type, underline, strikeout and more. For a full list check the ExcelFont properties.

The following example shows how you can format individual characters and words within an Excel cell.

        var cell = worksheet.Cells["A1"];
        cell.Value = "This is big and red text!";

        // Apply the size to "big and red" part of the text.
        cell.GetCharacters(8, 11).Font.Size = 400;

        // Apply the color to "red" part of the text.
        cell.GetCharacters(16, 3).Font.Color = SpreadsheetColor.FromName(ColorName.Red);

        cell = worksheet.Cells["A3"];
        cell.Value = "Formatting selected characters with GemBox.Spreadsheet component.";

        // Apply formatting on the whole cell content.
        cell.Style.Font.Color = SpreadsheetColor.FromName(ColorName.Blue);
        cell.Style.Font.Italic = true;
        cell.Style.WrapText = true;

        // Get characters from index 36 to the end of string,
        // e.g. the "GemBox.Spreadsheet component." part of the text.
        var characters = cell.GetCharacters(36);

        // Apply the color and underline to selected characters.
        characters.Font.Color = SpreadsheetColor.FromName(ColorName.Orange);
        characters.Font.UnderlineStyle = UnderlineStyle.Single;

        // Write selected characters.
        worksheet.Cells["A5"].Value = "Selected characters: " + characters.Text;

        workbook.Save("Inline Text Formatting.%OutputFileType%");
    }
}

        characters.Font.Color = SpreadsheetColor.FromName(ColorName.Orange)
        characters.Font.UnderlineStyle = UnderlineStyle.Single

        ' Write selected characters.
        worksheet.Cells("A5").Value = "Selected characters: " & characters.Text

        workbook.Save("Inline Text Formatting.%OutputFileType%")

    End Sub
End Module

HTML text formatting

Instead of using GetCharacters methods, another way to create a rich formatted text is to use an HTML text.

The following example shows how you can create an inline text formatting by setting the cell value with the ExcelCell.SetValue(String, HtmlLoadOptions) method.

        var htmlOptions = new HtmlLoadOptions();
        var html = "<h1 style='background:#DDEBF7'>HTML formatted text!</h1>";

        worksheet.Cells["A1"].SetValue(html, htmlOptions);

        worksheet.Cells["A3"].SetValue(html, htmlOptions);

        workbook.Save("Html Text Formatting.%OutputFileType%");
    }
