Implementation Guide

Loading a Source XLS File

Overview

Loading your source Excel file is the first step in the conversion process. This section shows you how to use GroupDocs.Conversion to load an XLS file.

Step 1: Define Input Path and Load File
using System;
using GroupDocs.Conversion;

string inputFilePath = "YOUR_DOCUMENT_DIRECTORY\sample.xls";

// Load the source XLS file
typing (var converter = new Converter(inputFilePath))
{
    // The converter is now ready for conversion operations.
}

This snippet loads your Excel file into the Converter object, making it ready for further actions.

Configuring Conversion Options for CSV

Overview

Configuring the correct options ensures that the conversion process outputs a properly formatted CSV file. Here’s how to set up these options using GroupDocs.Conversion.

Step 2: Set Up Conversion Options
using GroupDocs.Conversion.Options.Convert;

// Create an instance of SpreadsheetConvertOptions and specify the format as CSV
var options = new SpreadsheetConvertOptions { Format = SpreadsheetFileType.Csv };

The SpreadsheetConvertOptions class allows you to customize various conversion parameters, such as setting the output file type.

Performing the Conversion from XLS to CSV

Overview

This section covers executing the actual conversion process and saving the resulting CSV file.

Step 3: Define Output Path and Perform Conversion
using System.IO;
using GroupDocs.Conversion;

string outputFolder = "YOUR_OUTPUT_DIRECTORY";
string outputFile = Path.Combine(outputFolder, "xls-converted-to.csv");

// Perform the conversion from XLS to CSV
typing (var converter = new Converter(inputFilePath))
{
    // Execute the conversion and save the output file
    converter.Convert(outputFile, options);
}

This code performs the conversion and writes the resulting CSV file to your specified directory.
