Full Discussion: Combine multi-row cell into a single line

Are you able to install csvtool or csvkit? I know the former is able to work with multiline cells in a csv file; I don't know about the latter.

csvtool has a "call command" option allowing it to call a shellscript or shell function to modify the file one line at a time.

I think for the example you gave:
Code:
flatten() { echo "$1","$2","${3//$'\n'/ }","$4","$5" }
export -f flatten
csvtool call flatten file.csv

This is untested and you will have to try it out.

csvtool has the ablilty to cut and paste columns just like the cut and paste tools, so it might be easier to pull out the problem column, fix it as above. and paste it back into the original file.

I think you need version 4 of bash to get the $'' functionality, or look at using tr: tr '\r' ' '

paste

PASTE(1)						      General Commands Manual							  PASTE(1)

NAME

       paste - paste multiple files together

SYNOPSIS

       paste [-s] [-d list] file...

OPTIONS

       -d     Set delimiter used to separate columns to list.

       -s     Print files sequentially, file k on line k.

EXAMPLES

       paste file1 file2   # Print file1 in col 1, file2 in col 2

       paste -s f1 f2	   # Print f1 on line 1 and f2 on line 2

       paste -d : file1 file2
			   # Print the lines separated by a colon

DESCRIPTION

       Paste  concatenates  corresponding  lines of the given input files and writes them to standard output. The lines of the different files are
       separated by the delimiters given with the option -s. If no list is given, a tab is substituted for every linefeed, except  the	last  one.
       If  end-of-file	is hit on an input file, subsequent lines are empty.  Suppose a set of k files each has one word per line.  Then the paste
       output will have k columns, with the contents of file j in column j.  If the -s flag is given, then the first file is on line 1, the second
       file on line 2, etc.  In effect, -s turns the output sideways.

       If  a list of delimiters is given, they are used in turn.  The C escape sequences 
, 	, \, and  are used for linefeed, tab, backslash,
       and the null string, respectively.
