Talend generates code based on the components you drag and drop into your Job design canvas. When you use a component that handles CSV files, Talend’s code generator creates several helper classes to parse, quote, escape, and delimit rows. These classes are then compiled into a temporary JAR file. In older versions of Talend (especially v5.x and v6.x), this generated file was often named csv100.jar. talend csv100jar download link
The talend-csv-1.0.0.jar (internally referred to as CSV100) provides high-performance CSV parsing and writing capabilities for Talend Studio Jobs, especially when handling large or complex CSV files with custom delimiters, line separators, or escape characters.
