Implementation Guide

Feature: Loading an XLT File

Overview

Loading and preparing an XLT file for conversion is the foundational step in leveraging GroupDocs.Conversion’s capabilities. This feature allows you to read and convert .xltm files with ease.

Step 1: Define Document Path

Start by setting up the path where your documents are stored:

string documentDirectory = @"YOUR_DOCUMENT_DIRECTORY";

This directory should contain all the XLT files you intend to process.

Step 2: Specify File Path

Determine and combine the file path of your XLT file using Path.Combine for cross-platform compatibility:

string xltmFilePath = System.IO.Path.Combine(documentDirectory, "sample.xltm");
Step 3: Load the File with GroupDocs.Conversion

Utilize the Converter class to load and prepare your file:

using (Converter converter = new Converter(xltmFilePath))
{
    // Additional processing steps will follow here
}

Key Configuration Options

  • File Path: Ensure the path is correct and accessible.
  • Error Handling: Implement try-catch blocks for robust error management.

Troubleshooting Tips

  • Verify file permissions if you encounter access issues.
  • Double-check file paths for typos or incorrect directories.
