reCsvEditor

If you're looking for an easy-to-use Csv Editor, this program is worth considering. One of the best things about it is that it comes with built-in file format detection, which means you won't have to worry about manually specifying your file's format. Additionally, the program supports both single byte character sets and Unicode files, which makes it incredibly versatile.

The program also supports a large variety of field separators and quotes, making it easy to work with a wide range of file types. It offers multiple different file views, column updates, and the ability to handle large files without any performance issues. Plus, there's macro support - JavaScript comes built-in, but you can add Jython, JRuby, and other scripting languages as needed.

But this Csv Editor isn't just limited to CSV files. You can also use it to view and update XML, GNU-GetText-PO, and SwingX-Tip files. For fixed-width data files, there's a wizard that helps you easily define the file layout - this information is saved in an XML format so you can revisit it later. And if you're working with Cobol-layout files, there's an optional extension available too.

Finally, you can extend the editor with Java script, Jython, and JRuby macros - simply add the appropriate additional jars and you're ready to go. All in all, this program is a powerful and flexible tool for anyone who works with CSV files or other data formats on a regular basis.
