What is a CSV file?ĬSV files are ordinary text files comprised of data arranged in rectangular form. We will also go above and beyond to highlight the unofficial RFC 4180 technical standard, which attempts to document the format used by most CSV implementations. Some popular packages we will look at include csv-parser, Papa Parse, and Fast-CSV. We shall also highlight the slight variations in the different CSV implementations. In this article, we will learn how to manage CSV files in Node.

Most modern operating systems and programming languages, including JavaScript and the Node.js runtime environment, have applications and packages for reading, writing, and parsing CSV files. As a result, several implementations exist with slight variations. This is because there is no official universal CSV specification to which applications must adhere. Due to its popularity, it is not uncommon for governing bodies and other important organizations to share official datasets in CSV format.ĭespite its simplicity, popularity, and widespread use, it is common for CSV files created using one application to display incorrectly in another.
