Api or bulk upload for Shopify store help needed

Hi,dear. I am a senior software developer. I have just checked your project description, I am able to complete this project. I am looking forward to your proposal. Thanks.

Dear Prospect Hiring Manager. Thank you for giving me a chance to bid on your project. i am a serious bidder here and i have already worked on a similar project before and can deliver as u have mentioned "I can do this job and give you an efficient job that will be very acceptable and presentable. I and my team work on web development and mobile apps and I can assure you that you will never be disappointed"

Nice to hear you! This project could be done in 3 days by the team of our expert developers. We can perform both variants (Excel even easier), but we suggests you API one, because this will be more comfortable for you. Looking forward to hear from you via chat!
