I am looking for a free editor to edit comma-delimited text files, or .csv format.

    What do you need a special, CSV-specific editor to do that something like TextWrangler (or anything with column-based selections) can't do for you? Might help guide the answers if you could detail why something like Google Docs or CodeWrangler doesn't cut it for you. – Ian C. Jun 14 '11 at 13:56
  • Column-based selection won't help if the CSV has varying-width fields, right? – Alan Shutko Aug 22 '15 at 0:49

Google Docs

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

Free and Open Source (MIT License).

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

  • And it's fast to start and compatible with all the weird CSV gotchas floating around. +1 – a paid nerd Jan 13 '15 at 1:32


Disclaimer: Free on new Macs

Apple Numbers also opens and saves to CSV. Just had to add to the list.

Note that you can choose text encoding as well when exporting if needed for other systems.

    For my CSV editing needs (which are few) I use Numbers and TextEdit. – GEdgar Aug 22 '15 at 0:48

    Yep, that works. For me, Textastic or TextWrangler and Numbers work just fine. – bjbk Aug 22 '15 at 0:51
  • Is it possible to just save edits to an exisiting CSV file in place, i.e. just by pressing a shortcut key or click a menu item, without confirming the dialogues? – Frozen Flame Nov 4 '15 at 9:56

    Numbers doesn't really edit CSV. It imports and exports them, which is a much more awkward (and often useless) workflow. – orome Dec 24 '15 at 16:32


The latest version of NeoOffice works fine (in that it supports Versions etc) but you need to donate a small amount of money to download it before the end of August 2011.

    24$ yuck, to test a beta, probably never... others are paying you to test beta :) – sorin Aug 11 '11 at 17:34
  • I highly recommend NeoOffice. I have used it for eight years. It is a fork of OpenOffice and LibreOffice with Mac OS-specific features and fully suports Mac OS 10.7 Lion. You can download and use version 3.1 for free; only the most recent version 3.2 requires a donation. – user9290 Dec 24 '11 at 18:34

csveditor (Java)

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.

Free Microsoft Office Online

What better product than Excel is there to open and manipulate CSV files?

enter image description here

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.

Apache Open Office

Free. Reads, writes, creates CSV, Excel, Word and an number of other formats.
