Dear Statalist,

I downloaded data from the UN National Accounts. Unfortunately the layout of the data is not in the format I would like it. There is a line for each variable (e.g. output) for each year. That means that for a given country, there are multiple lines for a year. I would assume I would reshape this to wide and then back to long to do this, but I am really having trouble reshaping it.

The data is in long now and I would like it long but with a line for each country-year and more rows for the value of each variable at that year for that country. I would like something like this:
Country Year output intermed_cons gross_VA
Albania 2018 2.610e+12 1.180e+12 1.430e+12
Albania 2019 2.640e+12 1.160e+12 1.480e+12
Albania 2020 2.540e+12 1.100e+12 1.440e+12

And here is a sample of my data:
