When a CSV file is opened, all the separators line up vertically. You can select vertically a specified column, or sort values at a specified column or multiple columns. You can even sort only selected lines by sorting after selecting text or in conjunction with the narrowing mode.
The CSV/Sort toolbar was added in EmEditor v14.6, giving you easier access to different CSV formats and sorting commands. You can quickly edit the CSV file with various column/separator commands, the Delete Duplicate Lines command, Line Number, Ruler, and Heading commands. Moreover, the enhanced CSV features in EmEditor v14.6 gives you more options to customize your documents. You can define up to 8 CSV formats, and each format now allows up to 39 character long text. Each CSV format can be customized.
