CSV Converter is a simple application for opening, editing and saving CSV (Comma-separated values) files. The CSV file format is widely used to exchange data arranged in a table, like in a Numbers or Excel spreadsheet.
CSV Converter opens CSV files that some apps are having problems with, preview the tabular data and re-save it without the internal inconsistencies that cause the issue.
Additionally, it can export the table in various formats like RTF, Word and Open Document text or copy the table to the clipboard in the format that iWork uses.
There is very basic editing support, but the main purpose of the app is getting usable data out of CSV files.
