Implementation Guide

Load and Convert XLTX File to JPG

This feature converts an XLTX file into a series of JPG images, perfect for sharing spreadsheet data visually.

Step 1: Set the Output Directory Path

string outputFolder = "YOUR_OUTPUT_DIRECTORY";
// Define where your converted files will be saved.

Step 2: Define the Template for Output File Names

string outputFileTemplate = System.IO.Path.Combine(outputFolder, "converted-page-{0}.jpg");
// This template helps in naming each page of the document with a unique number.

Step 3: Create a Stream for Each Page of the Conversion Result

Func<SavePageContext, System.IO.Stream> getPageStream = savePageContext => new System.IO.FileStream(System.String.Format(outputFileTemplate, savePageContext.Page), System.IO.FileMode.Create);
// This function ensures each page is saved as a separate file.

Step 4: Load the Source XLTX File and Set Conversion Options

using (Converter converter = new Converter(filePath))
{
    // Define conversion options for JPG format
    ImageConvertOptions options = new ImageConvertOptions { Format = ImageFileType.Jpg };

    // Perform the conversion from XLTX to JPG
    converter.Convert(getPageStream, options);
}

Practical Applications

  1. Marketing and Presentations: Convert data-heavy spreadsheets into visually appealing images for presentations.
  2. Archival Purposes: Store spreadsheet templates as images in digital archives.
  3. Web Integration: Use the converted images on websites where users cannot interact with Excel files directly.
  4. Cross-Platform Sharing: Share information across platforms that do not support .xltx formats.
