The Facebook Marketplace CSV Generator Chrome Extension streamlines the process of creating listings for Facebook Marketplace. It leverages OpenAI's vision model to analyze images and automatically generate detailed product descriptions, titles, and other relevant information. This extension bridges the gap between visual content and structured data, saving time for sellers and improving listing quality.

• Image Analysis: Utilizes OpenAI's GPT-4 Vision API to extract product details from images.
• CSV Generation: Automatically creates CSV files compatible with Facebook Marketplace bulk uploads.
• Drag-and-Drop Interface: User-friendly image upload system for easy interaction.
• Customizable Settings: Allows users to manage their OpenAI API key for secure access.
• Test Mode: Facilitates development and debugging without making actual API calls.

The processImages function in background.js demonstrates efficient handling of multiple images using Promise.all:

async function processImages(images) {
  console.log('Processing images:', images);
  const apiKey = await getApiKey();
  if (!apiKey) {
    throw new Error('OpenAI API key not set. Please set it in the extension settings.');
  }

  const imageDescriptions = await Promise.all(images.map(processImage));
  console.log('Image descriptions:', imageDescriptions);
  const csvData = generateCSV(imageDescriptions);
  // ... rest of the function
}

This approach allows for concurrent processing of multiple images, significantly reducing overall execution time.

The extension implements a secure method for storing and retrieving the OpenAI API key using Chrome's storage API:

async function getApiKey() {
  return new Promise((resolve) => {
    chrome.storage.sync.get('openaiApiKey', (data) => {
      resolve(data.openaiApiKey);
    });
  });
}

This method ensures that sensitive information is stored securely and not exposed in the codebase.

The generateCSV function in background.js efficiently creates a CSV structure from the processed image descriptions:

function generateCSV(descriptions) {
  const csvRows = [['title', 'description', 'price', 'condition', 'category']];
  
  descriptions.forEach(description => {
    const rows = parseDescription(description);
    csvRows.push(rows);
  });

  return csvRows.map(row => row.join(',')).join('\n');
}

This function demonstrates a clean approach to data structuring and CSV formatting.
