How to Convert a Single Excel Cell to Image in C#

How to Convert a Single Excel Cell to Image in C#

Sometimes all you need is a single value — a price, a label, a code — and you want to export that cell visually. This tutorial shows you how to isolate and render a single Excel cell to an image using Aspose.Cells for .NET.

Real-World Use Cases

  • Export prices or totals for product displays
  • Isolate key metrics for dashboards
  • Generate image thumbnails for individual values

Step-by-Step Guide

Step 1: Install Aspose.Cells for .NET

dotnet add package Aspose.Cells

Step 2: Load the Workbook and Worksheet

Workbook workbook = new Workbook("KPIReport.xlsx");
Worksheet sheet = workbook.Worksheets[0];

Step 3: Select the Target Cell

// Example: Cell B5
Cell cell = sheet.Cells["B5"];

Step 4: Set the Print Area to the Cell

// Print only that one cell
sheet.PageSetup.PrintArea = "B5";

Step 5: Configure Image Rendering Options

ImageOrPrintOptions options = new ImageOrPrintOptions
{
    ImageType = ImageType.Png,
    OnePagePerSheet = true,
    HorizontalResolution = 300,
    VerticalResolution = 300
};

Step 6: Render Using SheetRender

SheetRender renderer = new SheetRender(sheet, options);
renderer.ToImage(0, "cell_b5_output.png");

Step 7: Save and Review the Output

You will get a clean PNG showing just that one cell with formatting intact.


Complete Example Code

using System;
using Aspose.Cells;

class Program
{
    static void Main()
    {
        // Load workbook
        Workbook workbook = new Workbook("KPIReport.xlsx");

        // Access the worksheet and target cell
        Worksheet sheet = workbook.Worksheets[0];
        Cell cell = sheet.Cells["B5"];

        // Set print area to that cell
        sheet.PageSetup.PrintArea = "B5";

        // Image export settings
        ImageOrPrintOptions options = new ImageOrPrintOptions
        {
            ImageType = ImageType.Png,
            OnePagePerSheet = true,
            HorizontalResolution = 300,
            VerticalResolution = 300
        };

        // Render and save
        SheetRender renderer = new SheetRender(sheet, options);
        renderer.ToImage(0, "cell_b5_output.png");

        Console.WriteLine("Cell B5 exported successfully as image.");
    }
}
