Implementation Guide

Loading Source OTS File

This feature demonstrates how to load your .ots file using the GroupDocs.Conversion library.

Step 1: Define Document Path

Specify the location of your OTS file:

string documentPath = "YOUR_DOCUMENT_DIRECTORY/sample.ots";

Step 2: Initialize Converter Object

Load the OTS file into a Converter object to prepare it for conversion.

var converter = new Converter(documentPath);
// Always dispose of resources when done to free up memory
converter.Dispose();

Setting Conversion Options for HTML

To convert your OTS file into an HTML document, set appropriate conversion options.

Step 1: Create Conversion Options Instance

Instantiate WebConvertOptions for web-friendly format conversions like HTML:

using GroupDocs.Conversion.Options.Convert;

var htmlConversionOptions = new WebConvertOptions();

Convert OTS to HTML and Save Output

Now, let’s perform the conversion and save your output file.

Step 1: Define Output Path

Set up where you want to store the converted HTML file:

string outputDirectory = "YOUR_OUTPUT_DIRECTORY";
string outputFile = System.IO.Path.Combine(outputDirectory, "ots-converted-to.html");

Step 2: Perform Conversion

Use the Converter instance to convert and save your document in HTML format.

using (var converterInstance = new Converter(documentPath))
{
    converterInstance.Convert(outputFile, htmlConversionOptions);
}
