Implementation Guide

Feature: PPTX to XLSX Conversion

This feature showcases how you can convert a PowerPoint file (.pptx) into an Excel spreadsheet (.xlsx).

Step 1: Define File Paths

Set up the input and output paths using constants for clarity:

string YOUR_DOCUMENT_DIRECTORY = "YOUR_DOCUMENT_DIRECTORY";
string YOUR_OUTPUT_DIRECTORY = "YOUR_OUTPUT_DIRECTORY";
// Define the input PPTX file path
string inputFilePath = Path.Combine(YOUR_DOCUMENT_DIRECTORY, "sample-presentation.pptx");
// Set the output folder and file path
string outputFolder = YOUR_OUTPUT_DIRECTORY;
string outputFile = Path.Combine(outputFolder, "pptx-converted-to.xlsx");

Step 2: Load the Source PPTX File

Utilize GroupDocs.Conversion to load your PowerPoint document:

using (var converter = new Converter(inputFilePath))
{
    // Conversion options will be specified in the next step
}

Step 3: Specify Conversion Options

Define how the conversion should be handled using SpreadsheetConvertOptions:

// Initialize options for converting to Excel format
var options = new SpreadsheetConvertOptions();

Step 4: Perform the Conversion

Execute the conversion and save the output as an XLSX file:

converter.Convert(outputFile, options);
