I have EDX results and I want to caculate clinoptilolite formula. How I can do it while this mineral have smoewhat diffren ideal formula with variou amount of alkali and alkali earth metal.
So, by "formula" you mean the stoichiometric composition, right?
Then you need the cross sections for all candidate elements, e.g. from a table like this:

The most important step in getting from an EDX intensity to a concentration is dividing I/CS.
You may also need instrumental parameters, e.g. a detector sensitivities, for which some instruments have an automatic correction implemented and others haven't. For that there is no way around checking the instrument's manual.
Also check out the website of your instrument's production company, they may provide specifice evaluation software for their tools, e.g. Bruker offers it directly in their detector software.
We can't measure it directly from EDX. It's only give us the stoichiometric concentration of the composition.
I am not fully following your question. You have stoichiometric composition in elemental form and wish to convert them to oxide format, such as the following?
(K, Na, Ca0.5, Sr0.5, Ba0.5, Mg0.5)6 [Al6Si30O72].30H2O)
