Your question is extremely broad. So I can only give very generic answers:

there is an introduction to OPL, the modeling language on top of CPLEX, at https://www.ibm.com/support/knowledgecenter/SSSA5P_12.9.0/ilog.odms.ide.help/OPL_Studio/opllanguser/topics/opl_languser_intro.html.
if you consider using a programming language, please have a look at https://www.ibm.com/support/knowledgecenter/SSSA5P_12.9.0/ilog.odms.cplex.help/CPLEX/GettingStarted/topics/preface/dataEntry.html
and if you want to directly generate a file that CPLEX can read, you should look into https://www.ibm.com/support/knowledgecenter/SSSA5P_12.9.0/ilog.odms.cplex.help/CPLEX/homepages/reffileformatscplex.html for the LP and MPS file formats.
