please help

Since you already know hoe to work with chemkin, you can directly import the mechanism files to fluent using the File > Import > Chemkin mechanism ...

You do not need to change the file format. If the files worked with Chemkin preprocessor, then they are in correct format to import. btw Fluent will only work with mechanism with 50 species or less.

can we use chemkin file with 180 species ?? If not is there any way to transform it to use in fluent

I guess you need to use reduced mechanisms.
Or you can eliminates some of the reactions (for instance, N2 reactions) by assuming it's an inert if you have the right problem statement.
