uniCSVed

uniCSVed is a tool that packs the same type of features as CSVed but with a different look, helping users easily edit Comma-Separated Values files (CSV format), thanks to a friendly environment.
The interface is made from a regular window with a seemingly cluttered layout, but which is actually quite simple to work with. CSV items can be imported into the workspace using either the file browser or drag-and-drop method.
However, since this app has not been updated for a very long time, it looks like uniCSVed has some stability issues on newer OS platforms. For example, it was unable to recognize a CSV file during our tests that we imported with the drag-and-drop support. But the app had no problems displaying its contents (same file) when using the file browser.
You can select any column of the file, edit records and expand rows by double-clicking entries. It is possible to set the separator type and starting row, add new records, edit or move columns, as well as join or split columns.
Other options of uniCSVed let you add a prefix or suffix value, insert leading zeros or delete the first/last count of characters, filter text, remove duplicate entries, append a file, use a search and replace function, and convert the CSV file to an XML item, among more.
uniCSVed has a minimum impact on the system performance, using a limited amount of CPU and RAM. It has a good response time to commands and performed well throughout our evaluation. The only downside is that the utility has been left unattended for so long. Otherwise, uniCSVed sports numerous handy features to satisfy all users who want to edit CSV files.
