You can read a comma separated file via the table command. See the
examples/csv folder and doc/gmpl.pdf. Tab separated files are not
supported. For larger data sets you can also use an ODBC data source.

FWIW I had problems using the csv input facility of glpsol 5-6 years ago.  So I 
wrote a program that generated GMPL files.  They were huge, but it worked very 
robustly.  I put the data in a separate file.  I was processing thousands of 
instances using shell scripts and a common model file.

The table command can be used to read a csv file or to connect to any ODBC data base.

Have a look at the directories doc and examples of the source distribution.

Suppose I have a lp problem with hundred constraints and variables of the
same order then it becomes problematic to create a .lp file manually. So,
is there a way to provide the input from an excel sheet or some other
plain-text format.

Thank you
