Hi, there!
My name is Paris, and I was glad to see that you're looking for an Excel developer. According to your brief, you want to have an Excel macro that will merge two separate datasets. I'll make it so that you'll be able to repeat this process for as many times you like regardless of the records number of the two datasets. I will charge you 90 pounds and can deliver within a couple of days (a single milestone to release once you're satisfied with the final result).
I'm among the most experienced and skilled Excel, and VBA developers on this platform. I am in the top 3% of the freelancers having completed over 300 projects successfully in six years, and I feel confident in achieving your task as well. You're welcome to visit my page (https://www.freelancer.com/u/paris2785) and get an idea of who I am and what services I provide to my clients.
I'm online from 8 am to 9 pm, Athens time (including weekends).
I'm looking forward to working with you.
Sincerely,
Paris Pallas
