Univocity-parsers is an open-source Java project. For csv/tsv/fixed-width text file parsing, it provides a rich and powerful function with the Simple API development interface. Further introductions will be made later.Unlike other analytic libraries, Univocity-parsers has designed a set of own architectures based on high performance and scalability. Based on this architecture, developers can build a new file parser.1. OverviewAs a Java developer, I am

CSV table files are comma-delimited, and others have a TSV file with Tab tab as the cell delimiter, and others are table files that define other separators.
