Create group members in bulk on Whatsapp

I am looking for a freelancer to help me create a list of members in bulk on Whatsapp. These members should all come from a spreadsheet that I have prepared. I don't have any special software requirements and I don't need assistance creating a Whatsapp business account. This project requires knowledgeable people who can use effective and secure methods to complete the task. If you are qualified and have the necessary skills, please get in touch and let me know what solutions you can offer.
