I am looking for a free editor to edit comma-delimited text files, or .csv format.
I just used Google Docs for exactly this purpose but all I needed to do was extract a column of email addresses from a CSV file.
Note: Google Docs has file size limits, so this is not a silver bullet. A great bullet, but those limitations are critical when applied.

Table Tool opens CSV files. It auto-detects character encoding and record separator (comma/semicolon/tab), and supports basic editing operations (like add row, delete row, add column delete column etc).
Table Tool can convert files to a different format.
Table Tool is also available on the Mac App Store.
LibreOffice does quite a good job now and is compatible even with OS X 10.9
Disclaimer: Free on new Macs
Apple Numbers also opens and saves to CSV. Just had to add to the list.
Save as CSV after editing:
Note that you can choose text encoding as well when exporting if needed for other systems.
Not an obvious candidate but very powerful (and free).
- Create an empty Database
- Import Table form CSV file
- With various import options
- Edit, search, plot the data
- Export your edits as (new) CSV file
Very simple (no undo), java program (some may stop reading here ;) - does the job
You have to create an empty table upon launch but then you can open any file.
What better product than Excel is there to open and manipulate CSV files?
With this option, you don't need to install anything. It has the convenience of Google Docs but the guaranteed compatibility of MS Office.
When interacting with large and messy text csv and other structured text files, I now typically go to Google Refine (now called OpenRefine). I've used it for TSV/CSV, JSON, and XML documents. In my experience it crashes rarely, and is pretty good for mangling data (you can apply transformations with scripting languages).
Its approach is more database-oriented, rather than spreadsheet oriented.
RStudio wraps a really nice IDE-like environment around the popular, open source R language. The R language "is an integrated suite of software facilities for data manipulation, calculation and graphical display."1 It includes facilities for importing and exporting CSV data from its built-in data store so you can work on it with its powerful toolkit and then export it back out to CSV.
It's free (as in beer and speech) for use with paid options available if you need someone to yell at when things aren't working quite right.
Free. Reads, writes, creates CSV, Excel, Word and an number of other formats.
XTabulator edits CSV but is not free.
XTabulator is a tabular data file editor for Mac OS X. With XTabulator, you can edit, manipulate, massage, slice, and dice comma-separated (CSV), tab-separated (TAB), or anything-separated files quickly and easily.
