Apply Excel Cell text color
  • In EPPlus, ExcelRange class has a style property. This style property is the type of ExcelStyle (seal) class.
  • ExcelStyle class has another ExcelFont (seal) type font properties.
  • ExcelFont class has ExcelColor (seal) type colorproperty. ExcelColor has SetColor method. This method can accept Colorstructure object as a parameter.
Example
  • ExcelRange Rng = new ExcelRange();
  • Rng.Style.Font.Color.SetColor(Color.Red);
*By default, EPPlus supports Black font color, if you are not specifying any Font color.

Now, the next question in our mind is how to set cell background color?

Example
  • Rng.Style.Fill.PatternType = ExcelFillStyle.Solid;
  • Rng.Style.Fill.BackgroundColor.SetColor(Color.Green);
  • Here SetColor method can support structure Color property as a parameter.
  • You can also specify the HTML Color code.
*By default, EPPlus supports White background color.

For Example
  • Color DeepBlueHexCode = ColorTranslator.FromHtml("#254061");
  • Rng.Style.Fill.BackgroundColor.SetColor(DeepBlueHexCode);
  • In this example FromHtml() directly accept HTML RGB (Red Green Blue) color Code.
Output on an Excel sheet is given below.

  1. using OfficeOpenXml;
  2. using System.IO;
  3. using System;
  4. //add two new namespace
  5. using OfficeOpenXml.Style;
  6. using System.Drawing;
  7. class Program {
  8. static void Main(string[] args) {
  9. ExcelPackage ExcelPkg = new ExcelPackage();
  10. ExcelWorksheet wsSheet1 = ExcelPkg.Workbook.Worksheets.Add("Sheet1");
  11. using(ExcelRange Rng = wsSheet1.Cells[2, 2, 2, 2]) {
  12. Rng.Value = "Welcome to Everyday be coding - tutorials for beginners";
  13. Rng.Style.Font.Size = 16;
  14. Rng.Style.Font.Bold = true;
  15. Rng.Style.Font.Italic = true;
  16. }
  17. //First Border Box
  18. using(ExcelRange Rng = wsSheet1.Cells[5, 2, 8, 4]) {
  19. Rng.Value = "Text Color & Background Color";
  20. Rng.Merge = true;
  21. Rng.Style.Font.Bold = true;
  22. Rng.Style.Font.Color.SetColor(Color.Red);
  23. Rng.Style.Fill.PatternType = ExcelFillStyle.Solid;
  24. Rng.Style.Fill.BackgroundColor.SetColor(Color.LightBlue);
  25. }
  26. wsSheet1.Protection.IsProtected = false;
  27. wsSheet1.Protection.AllowSelectLockedCells = false;
  28. ExcelPkg.SaveAs(new FileInfo(@ "D:\New.xlsx"));
  29. }
  30. }
Now, build & execute the given code. File is (New.xlsx), which is stored on D: drive of the computer.
