CSV files (comma-separated values) are often used to save tables of data in plain text. Following are some useful techniques for working with CSV files. You can:

  • Highlight all text in any column.
  • View fields (convert csv text to columns or separate lines).
  • Navigate using the HJKL keys to go left, down, up, right by cell (hjkl work as normal).
  • Search for text in a specific column.
  • Sort lines by column.
  • Delete a column.
  • Specify a delimiter other than comma.

Highlighting a columnEdit

It's easy to find a column in csv text if you source the following script. Enter a command like :Csv 23 to highlight column 23.

" Highlight a column in csv text.
" :Csv 1    " highlight first column
" :Csv 12   " highlight twelfth column
" :Csv 0    " switch off highlight
function! CSVH(colnr)
  if a:colnr > 1
    let n = a:colnr - 1
    execute 'match Keyword /^\([^,]*,\)\{'.n.'}\zs[^,]*/'
    execute 'normal! 0'.n.'f,'
  elseif a:colnr == 1
    match Keyword /^[^,]*/
    normal! 0
command! -nargs=1 Csv :call CSVH(<args>)

Highlighting the header rowEdit

If the first row is a header row, you can highlight the header fields by putting the following lines in the file syntax/csv.vim (see syntax highlighting for moin). This requires csv file type detection (see Usage below).

syntax match csvHeading /\%1l\%(\%("\zs\%([^"]\|""\)*\ze"\)\|\%(\zs[^,"]*\ze\)\)/
highlight def link csvHeading Type

Viewing csv fieldsEdit

The following commands can be entered to convert csv text to columns for easy viewing. Work on a temporary copy of your data because these commands will damage it!

" Convert csv text to columns (press u to undo).
" Warning: This deletes ',' and crops wide columns.
:let width = 20
:let fill = repeat(' ', width)
:%s/\([^,]*\),\=/\=strpart(submatch(1).fill, 0, width)/ge

Alternatively, you can change each comma to a newline to put each field on its own line:

" Change CSV fields on current line to a list of separate items.
" Same, for all lines.

In the replace text of a substitute, \r substitutes a newline.

Navigating in csv textEdit

The simple script given above does not provide easy navigation, and it assumes that commas are only used as delimiters. The following code has more features, and it is presented as a plugin due to its length.


  • Fields are generally correctly highlighted, according to the CSV specification: quotes, commas inside quotes, quote inside quotes are all correctly processed.
  • (However it does not handle quoted fields that begin with a space before the quote, i.e. where the delimiter is ", " so for this see work-around below)
  • It does not go beyond the last column (from a count of the columns in the first and last three lines).
  • HJKL go left, down, up, right by "cell". Focus is set to the first character of the cell.
  • 0 and $ highlight the first and last cell. Focus is set to the first character of the cell.
  • Ctrl-f, Ctrl-b page forward and back, while staying in the same column.
  • \J is Join :help J and \K is Keyword :help K (assuming the default \ local leader key :help maplocalleader).
  • The column number and heading are displayed when moving around. The headings are taken from a specified line, by default, the first line.
  • Search within column. The command
    :SC n=str
    will search for str in the n-th column. If "n=" is omitted, the search is within the currently highlighted column. For example:
    :SC 2=john  " search for john in the 2nd column only
    :SC john    " search for john in the currently highlighted column
    Case sensitivity is the same as for / (toggle with :set ic! ic? see :help 'ignorecase'). After the search, the @/ variable is set. So, for example, after :SC 2=john, one can use g//d to delete all lines whose second field contains john.
  • Copy column. The command
    :CC n x
    will copy (yank) the n-th column to register x. If n is omitted, then the current highlighted column is copied. If x is omitted, the unnamed register is used. Examples:
:CC              " copy current column to unnamed register
:CC 12           " copy column 12 to unnamed register
:CC a            " copy current column to register a
:CC 12 a         " copy column 12 to register a
  • Delete column. The command
    :DC n
    will delete the n-th column. If n is omitted, then the current highlighted column is deleted.
  • Change the headings line. By default the first line is assumed to contain column headings, but you can change the line used with the HL command. Note that the headings line is a fixed line number; it does not update if that line is moved, for example if you delete or insert lines above it. Also, the headings line value will be reset to 1 (the default) if you reload the buffer, for example, with the :e! command.
:HL 3            " set the third line of the buffer to contain the column headings
:HL              " set the line currently under the cursor to contain the column headings
:HL 0            " turn off the headings line
  • Specify a character to be used as the delimiter (',' is the default).
:Delimiter       " show delimiter
:Delimiter ;     " set delimiter to ';'
:Delimiter \t    " set delimiter to the tab character

Delimiters can only be one character. For multi-character delimiters see the work-around below)

  • Change the default delimiter (you could put one of the following examples in your vimrc):
:let g:csv_delimiter = ";"
:let g:csv_delimiter = "\t"
  • Sort lines by column. This works like the :sort command except that the specified field is used for sorting. The heading line and lines above it in the buffer are not included, unless you explicitly specify a range that starts on or before the heading line. To sort all lines, explicitly specify the range, or turn off the headings line. Some examples follow.
                 " Assuming the heading line is line 1, the default

:Sort            " sort by the current column excluding line 1
:Sort 3          " sort by column 3 excluding line 1
:Sort! 3         " same, reverse order
:5,12Sort! 3     " same, but sort only lines 5 to 12 inclusive
:Sort n          " numeric sort by the current column
:Sort 3 n        " same, by column 3
:Sort 3 x        " same, hex numbers
:Sort i u        " ignore case; omit duplicate lines (keep unique)
:Sort iu         " same
:Sort 3 iu       " same, by column 3

                 " Assuming the heading line is line 5

:Sort            " sort only lines 6 to end of buffer
:%Sort           " sort the whole buffer, including heading line
:5,$Sort         " sort lines 5 to end of buffer, including heading line
:4,$Sort         " sort lines 4 to end of buffer, including heading line
:1,6Sort         " sort lines 1 to 6, including heading line

                 " Assuming the heading line is line 0 (disabled)

:Sort            " sort the whole buffer

" The n and x options use integers ("12.9" is 12, overflow is ignored).
" Use the f option for floating point (:version must show +float).
" Non-numbers sort before numbers.
:Sort f          " sort using floats in current column
:Sort 3 f        " same, by column 3
:5,12Sort! 3 f   " reverse sort lines in range using column 3 floats


Put a .csv rule in filetype.vim

au! BufNewFile,BufRead *.csv setf csv

Create file ~/.vim/ftplugin/csv.vim (Unix) or $HOME/vimfiles/ftplugin/csv.vim (Windows) containing the script below.

Open a file (named anything.csv) that contains fields separated by commas. Use H J K L 0 $ to move from cell to cell.

If you open a *.csv file, the current column will be highlighted. Conversely, you may open a file with csv data, yet the file is not named *.csv, so highlighting will not occur.

You can switch highlighting off by setting the filetype option to nothing:

:set ft=

This command switches highlighting on:

:set ft=csv

The codeEdit

This is the ftplugin csv.vim script:

Explanation of the regular expressionEdit

The above code is fairly easy to understand, except perhaps for the regular expressions. The following regex (inspired by RegExLib 1520) is used several times:


It is explained as follows:

1.  \%(                 # unbackref'ed grouping for one CSV field
2.     \%(              # first possibility of a field
3.        "             # starts and ends with "
4.        \zs           # beginning of matched string
5.        \%(
6.           [^"]\|""   # anything not ", or a "" (escaped quote)
7.        \)*
8.        \ze           # end of matched string
9.        "
10.    \)               # end first possibility of field
11.   \|                # or
12.    \%(              # second possibility
13.       \zs
14.       [^,"]*        # anything but " and comma
15.       \ze
16.    \)
17. \)

Working with multi-character delimitersEdit

The delimiter can only be one character. This causes the code to fail with delimiters of more than one character, notably if there is a space after each comma (i.e. you want to set delimiter to ", ").

As a workaround you can put this code into your vimrc, the idea is to temporarily replace the multi-character delimiter with a comma. The file will be read-only but you can save changes to a new name. Changes will be silently abandoned if you just close the file. Notice it will change all values that look like the delimiter, even within quoted fields where they are not delimiters. (If your delimiter isn't ", ", modify the code accordingly.)

autocmd BufWinEnter *.csv set buftype=nowrite | :%s/, /,/g

Working with Excel xls filesEdit

One can use the xls2csv Perl script to convert Excel files to CSV, and then view/edit with Vim. You may put the following code in your vimrc:

autocmd BufReadPre *.xls set ro | setf csv
autocmd BufReadPost *.xls silent! %!xls2csv -q -x "%" -c -
autocmd BufReadPost *.xls redraw

It will view the XLS file in readonly mode as a CSV file by first converting on-the-fly.

  • quick comment: (2013-01-31) I changed csv.vim as follows since I often have wrapmargin set to a positive number in, for instance, markdown files.
  • There's also exist rainbow_csv plugin for highlighting csv columns in different colors. It can be found on github: rainbow_csv
< setlocal nowrap textwidth=0
> setlocal nowrap textwidth=0 wrapmargin=0
< let b:undo_ftplugin = "setlocal wrap< textwidth<"
> let b:undo_ftplugin = "setlocal wrap< textwidth< wrapmargin<"
