I import a data from a web site with API, the data is a single char, 1-by-1, and I need to convert in a table with 3 columns, {year, month, data}

Can you give a screenshot of how the table looked on the website?
Assuming that the character vector is stored in a variable named DATA, please show us

Suppose you have the character vector stored in the variable S. Then:
info_struct = regexp(S, '(?<Year>\d{4})\s+(?<Month>[A-Za-z]{3})\s+(?<Hh>\d+(\.\d+)?)','names');
Year = str2double({info_struct.Year}.');
Month = vertcat(info_struct.Month);
Hh = str2double({info_struct.Hh}.');
YourTable = table(Year, Month, Hh);
