Hello Shivangi17, welcome. Please have a look at the Perl Monks guide to the Monastery and How do I post a question effectively?

If you're very new to Perl, you should probably start with perlintro.

Normally one would read a CSV file with the module Text::CSV. There are several modules to generate HTML output for you, take a look at the CPAN. One module of many is HTML::Template, or in your case maybe HTML::Table would be helpful.

Your question does not include enough sample input and output data to give a good answer. Especially the output: I am only guessing that you're talking about HTML? Will the CSV rows be embedded into an HTML file, or transformed into the desired output format in some other way?

Please have a look at the documentation linked above, and provide more sample input data and some of the expected output. If you've written some code that you have questions about, please feel free to post that here too.
