How to resolve the algorithm CSV to HTML translation step by step in the UNIX Shell programming language

Table of Contents

Problem Statement

Consider a simplified CSV format where all rows are separated by a newline and all columns are separated by commas. No commas are allowed as field data, but the data may contain other characters and character sequences that would normally be   escaped   when converted to HTML

Create a function that takes a string representation of the CSV data and returns a text string of an HTML table representing the CSV data. Use the following data as the CSV text to convert, and show your output.

Optionally allow special formatting for the first row of the table as if it is the tables header row (via preferably; CSS if you must).

Let's start with the solution:
