CSV, or Comma-Separated Values, is a text file format that uses commas to separate values. Each line in the file represents a record, with fields separated by commas, though other characters like semicolons or tabs may also serve as separators.

The CSV format is widely utilized for data transfer in various applications due to its convenience for exporting and importing data. For instance, databases often export data in CSV format, especially for handling large datasets.

There are situations where it becomes essential to compare CSV files, such as identifying discrepancies between two exported files. This task can become challenging, especially with large CSV files. Our tool addresses this challenge by providing an easy and efficient way to compare CSV files.
