Top 4: Online CSV Viewer Options

Let’s talk about CSV files! And more importantly options to view CSVs in the browser. CSV stands for a "comma separated values", which basically means that within the file is a collection of data with a comma between each data value. CSV files are an essential part of data analysis and research. Historically CSVs have been viewed on the desktop. But because provide arguably the easiest way to store and share data, it's becoming more important to view CSV files online. Especially since not everyone can view these files on their computer because of the lack of software, hardware support, or because they are not able to (or choose not to) download them. So it's no surprise that online CSV viewers have become more popular.
