Hello there and an official welcome to the forums!
I just wanted to chip in with my personal experience of getting my girl to eat pellets
Also, even if you do switch your little guy onto just pellets, he still needs a little bit of seed each day, as well as veggies, to maintain variety and health in his diet. Seeds aren't bad--they're just high in fat. They are healthy fats, though, and small amounts will not hurt him
Weaning budgies onto pellets can take forever and be extremely frustrating. The way I did it was in ratios: Every time you change their food, add in a few more pellets, then a few more, then a few more (about a teaspoon more every two days) and after a week, the ratio should be at about 25-30% pellets to 70-75% seeds. At this point, they usually only ate the seeds, and then begged for more seeds, ignoring the pellets.
At this point, do not give in to their begging for more seeds. Most birds will only begin to eat pellets after there's no other option.
This seems kind of dramatic, but that was the way my little girl learned to eat pellets, and now she loves them!
Eventually, increase the pellets until they are 50-50 with the seeds, and finally mostly pellets, then cut out seeds entirely.
Keep in mind that you'll have to monitor him closely to ensure he tastes the pellets. Some birds would rather starve, so if he is absolutely not eating them (it's ok to wait for a day or so) then re-introduce seeds, and either try again, or use another method to get him to accept the taste of pellets, as mentioned
Hope that helped a little bit--and I hope to see you around! Feel free to post a picture of your little man when you have the time
It's great to have you with us!
