Cloudmarsive API-integration

This is a full‑stack document conversion web application engineered as a Node.js/Express server that acts as a lightweight yet powerful API wrapper for the Cloudmersive conversion service, exposing over 60 distinct conversion pathways across multiple document formats—including Word, Excel, PowerPoint, PDF, HTML, CSV, and image formats. The frontend is rendered via EJS templating with a modern, dark-themed Bootstrap 5 interface, while the client‑side logic is orchestrated through jQuery, featuring a progressive step‑indicator workflow, drag‑and‑drop file uploads, dynamic extra‑option panels, and real‑time file preview chips with individual removal capabilities.
