How to Retrieve Text Color of a Cell Value in Excel Using OpenXML and C#

When working with Excel files in C# , especially using the OpenXML library, developers often face challenges not only in retrieving cell values but also in maintaining their original formatting, which includes text color. If you've ever tried to extract data from an Excel file and found yourself frustrated by the lack of text color information, you're not alone. This post will guide you through effective methods to retrieve text colors within cells, enabling you to display them accurately in your applications.

Understanding the Problem

Retrieving the text color of a cell in an Excel file can be tricky due to the various ways colors are represented in the underlying XML structure. The text color could either be defined directly using RGB hexadecimal codes or linked to a theme color defined in the Excel file's color scheme. Many developers struggle with obtaining the correct color, often encountering issues where the color is not available or is represented as an index rather than an RGB value.

Here's a common scenario:

You've managed to retrieve the values from an Excel file.

Now you want to make sure any text is displayed in the same color as it appears in the original file.

However, the methods you've tried either return null or provide color indices rather than the actual colors.

Solutions to Retrieve Text Color

Fortunately, after some exploration, I've found two effective methods to retrieve text colors from Excel using OpenXML. Let’s break down these approaches step by step.

Method 1: Retrieving Colors from Color Schemes

Iterate through TableCellProperties: Start by iterating through the TableCellProperties of the cell you're inspecting. This helps locate any solid fill properties associated with the cell's text.

Check for Solid Fill: Within the cell properties, look for SolidFill elements.

Identify Scheme Color: If you find that sldFill.SchemeColor is not null, it indicates that the cell text is utilizing a color defined in the color scheme of the Excel file. You can then access the color scheme.

Retrieve RGB Values: Iterate through the color scheme to retrieve the RGB value corresponding to the color name found in the scheme.

Method 2: Directly Retrieving RGB Hex Codes

Alternatively, you can directly check if the SolidFill has an RGB color defined.

Check for RGB Color: If sldFill.RgbColorModelHex is not null, this indicates a direct RGB value is available.

Use the Retrieved Color: Directly use the retrieved hex code in your application to apply the color to your displayed text.

Conclusion

By utilizing these methods, you can effectively retrieve the text color of cell values in Excel documents using OpenXML in C# . Whether your colors are defined by an RGB code or linked to a color scheme, you now have the tools necessary to represent your data accurately. This clarity will enhance the user experience of your application by ensuring visual consistency with the original Excel file.

If you’ve faced issues retrieving colors, try these steps, and you’ll likely find the solution you need to display your data beautifully.
