Basic Initialization and Setup with C# Code

To initialize GroupDocs.Conversion, import necessary namespaces:

using System;
using System.IO;
using GroupDocs.Conversion;
using GroupDocs.Conversion.Options.Convert;

// Initialize the Converter object with the path of the input JLS file.
var converter = new Converter("YOUR_JLS_FILE_PATH");

Implementation Guide

Follow these steps to convert JLS files to XLS format.

Step 1: Set Up Directories and File Paths

Define paths for your source and output directories:

string documentDirectory = "YOUR_DOCUMENT_DIRECTORY";
string outputDirectory = "YOUR_OUTPUT_DIRECTORY/";

// Combine paths to specify the input JLS file and the output XLS file.
var jlsFilePath = Path.Combine(documentDirectory, "sample.jls");
var outputFile = Path.Combine(outputDirectory, "jls-converted-to.xls");

Step 2: Load Source File

Use the Converter class to load your source JLS file:

using (var converter = new Converter(jlsFilePath))
{
    // Proceed with configuration and conversion options.
}

Step 3: Configure Conversion Options

Specify the target format as XLS:

var convertOptions = new SpreadsheetConvertOptions { Format = SpreadsheetFileType.Xls };

Step 4: Perform Conversion

Execute the conversion using the Convert method and save the output file:

converter.Convert(outputFile, convertOptions);

Practical Applications

This JLS to XLS conversion feature is useful for:

  1. Data Analysis: Convert image-based data into Excel sheets for better manipulation.
  2. Reporting: Automate report generation by converting image logs stored in JLS format.
