I am very new to coding. I have a large data set of (x,y) coordinates of about 1000 points, and I know to do other things, I need to have a comma in between each point. With that being said, I do not want to manually have to put in 1000 commas every time I need to do this analysis. My ultimate goal is to make a code that will deconvolute the data. We theoretically have four peaks in each graph, but it is not always certain if one is present and is being drowned out by a larger peak, or if it simply is not present.

I did try #in_(x coordinates); but before I could even try the rest to get the output, there was an error saying something about the formatting. I tried pasting the x-values in as rows and as columns, but I had the same message each time. I hope it is not because of the size of the data.
