Language Translation

Translates structured HTML content using Google Translate API, injects custom CSS styling, converts translated HTML to professional PDFs via ConvertAPI, and finalizes PDF files with language-specific naming.

Join & EMail Prep

Merges translated PDF outputs from both lanes (Language 1 and optional Language 2), assembles email data with proper attachments, and prepares user notification with document details.

Cost Logging

Calculates translation expenses including Google Translate character costs, ConvertAPI PDF conversion fees, and Gmail delivery costs, then stores detailed cost breakdown in data table for analytics.
