Is there a way to sort the bibliography alphabetically?

Question

I am new in latex. My problem is the bibliographer is not ordered alphabetically. Is there a way to sort the bibliography alphabetically?

\documentclass[a4paper,12pt,openany]{book}
\usepackage[
  backend=biber, % bibtex  % bibtex or biber (prefered)
  natbib=true,
  style=alphabetic,
  sorting=none  % none, nty % no sorting or standard sorting
]{biblatex}
\addbibresource{bibliogra.bib}
\begin{document}
\cite{Bal89}, Balder E.J. \cite{DeB86} De Blasi F.S. and  Myjai J \cite{Dil93}, Dilworth S.J., Girardi M.; \cite{Gue97}, Guessous M. \cite{Kru00}, author=Krupa G.,\cite{Bal90}, author is Balder E.J., \cite{Kom67}.
\printbibliography
\end{document}

the result :

Answer 1

The names are not input correctly. Family G. I. is not a valid format. If you use the reversed format, you need a comma

Family, G. I.

the other accepted format here would be the natural order

G. I. Family

Which method you choose does not matter for the output – as long as it is correct input.

So

*author={Komlós J.}, should be

author={Komlós, J.},

You also must separate multiple names with and regardless of the desired output: *author={Dilworth S.J., Girardi M.}, is wrong, it should be

author={Dilworth, S.J. and Girardi, M.},

See also How should I type author names in a bib file? and How to properly write multiple authors in bibtex file?.

Note that sorting=none, will give you sorting by citation order. You probably don't want that with style=alphabetic. That style already chooses a sensible sorting (sorting=anyt), so you can just say
