The JetBrains IDEs have integrated a new CSV Editor plugin that designates CSV (Comma-Separated Values) as a formal language, complete with a defined syntax, structured language components, and relevant file extensions (.csv/.tsv/.psv). This functionality enables standard editor capabilities such as syntax validation, highlighting, and inspections for files that resemble CSV formats. Users can enjoy customizable text and table editors, along with versatile table editing options, syntax validation, and tailored syntax highlighting and formatting. Additionally, it offers quick-fix inspections and useful intentions like quoting and unquoting text or shifting columns as needed. The plugin is designed to handle various value separators, including tab characters, and it permits the use of custom separators and line comments for enhanced flexibility. With the table editor, users can easily add or remove rows and columns through context menus, and it also supports keyboard shortcuts for smoother navigation and management of data. This makes working with CSV files more intuitive and efficient for developers.
