I need a lightweight web-based tool that lets me fire off WhatsApp campaigns to large contact lists in one go. The core requirement is straightforward: once I upload an Excel sheet of numbers, the system should connect to my active WhatsApp session (web API or any proven workaround), pull each contact, and send a predefined text message to all of them automatically. Getting reply too Key details • Primary action is bulk sending; scheduling or analytics can be left for future iterations. • Contacts arrive exclusively through Excel uploads for now, but it would be helpful if the codebase is organized so additional file types (CSV or plain TXT) could be enabled later without major rewrites. • A simple dashboard that shows basic status feedback while messages are going out (total numbers processed, successes, and any immediate failures) will be enough for this version. Tech notes & acceptance • Web interface can be plain HTML/CSS/JavaScript backed by PHP, Node.js, or Python—feel free to use the stack you’re fastest with, as long as setup instructions are clear. • I should be able to deploy it on a standard shared hosting or a small VPS; keep external dependencies minimal. • Provide full source code, a short README for installation, and a quick demo video or screenshots proving the blast works with a sample Excel file. If the tool reliably imports an Excel list and sends the message to every contact in that sheet, the job is done.

Hello, I see you're looking for a solution to automate WhatsApp campaigns efficiently. I propose developing a streamlined, web-based tool optimized to handle extensive contact lists through an Excel upload. 1. With Python and Node.js, we can establish a robust backend to integrate with the WhatsApp API securely, ensuring messages are dispatched swiftly and reliably. 2. The frontend will be crafted using HTML, CSS, and JavaScript to create a user-friendly interface for easy navigation and operation. 3. We'll implement an automation script that parses Excel files, extracts phone numbers, and triggers message sends, all while maintaining compliance and security. 4. Leveraging PHP for server-side operations will ensure smooth handling of concurrent requests and data processing. This approach ensures a seamless process optimized for performance and ease of use, saving you time and effort with your campaigns. Best Regards, Khorshed Alam, RS Software

I will develop a lightweight web-based tool to send WhatsApp campaigns to large contact lists in one go. To achieve this, I will use a proven workaround to connect to your active WhatsApp session, pull each contact from the uploaded Excel sheet, and send a predefined text message to all of them automatically. I will also ensure that the system can handle getting replies. I have previously worked on a similar project, Telegram Trade Signal Bot, where I developed a bot to parse and forward trade signals using regex-based filtering and user-specific preferences. In this project, I implemented regex logic to extract key trade data from unstructured messages and integrated user authentication and API access control. Can you please confirm if you have a preferred tech stack for this project or if you would like me to suggest one? Also, would you like to prioritize the development of the system to handle a large volume of contacts or focus on the simplicity of the dashboard?
