I’ve got an XLSX file filled with phone numbers and a single pre-written message ready to go. What I need—within the next two hours—is a quick way to fire that message out as a WhatsApp broadcast without having to copy-paste or add the contacts by hand. You’re free to build a lightweight script (Python, Node, or anything you’re comfortable with), leverage the WhatsApp Business Cloud API, or connect an off-the-shelf tool that supports bulk sending; I just need something reliable that I can run right away. Acceptance criteria • Your solution ingests my existing XLSX list directly. • It pushes the pre-written text to every number on WhatsApp in one batch. • No manual entry of contacts is required at any stage. • You walk me through the short setup so I can replicate the process whenever I update the list. If you can deliver a working solution inside the two-hour window, let’s do it.
