will your script work for the above ?

My point is the script should replace comma with pipeline at the same time it should check whether the column has comma inside the double qouted qualifier for each record and shouldnt replace those. A column will have double qoutes in the data only if it has comma inside it. Next month i may get different column which has comma inside it and being double qouted.
Why you don't try by yourself...?

Please use code tags for code and data sample.
And always provide every details about input and desired output.
Please try to give your desired output.

please check..

Code:
$ cat file
Menstrain,A0022699,"Woodstock,IL,2",A0013195,"Rockford,IL",A0013243,"Chicago,IL","EMERGING,QUALITY"
Menstrain,A0022699,Woodstock,IL,2,A0013195,Rockford,ILA0013243,Chicago,EMERGING,QUALITY
"Menstrain,arr",A0022699,"Woodstock,IL",2,"A001,3195",RockfordIL,"A001,3243","Chicago,america",EMERG INGQUALITY

$ awk -F '"' 'NF>1{ for(i=1;i<=NF;i+=2){gsub(",","|",$i)}}
NF==1{gsub(",","|")}1' OFS='"' file
Menstrain|A0022699|"Woodstock,IL,2"|A0013195|"Rockford,IL"|A0013243|"Chicago,IL"|"EMERGING,QUALITY"
Menstrain|A0022699|Woodstock|IL|2|A0013195|Rockford|ILA0013243|Chicago|EMERGING|QUALITY

mdb-tables

MDBTools(1)															       MDBTools(1)

NAME

       mdb-tables - Get listing of tables in an MDB database

SYNOPSIS

       mdb-tables [-S] [-1 | -d delimiter] database

DESCRIPTION

       mdb-tables is a utility program distributed with MDB Tools.

       It produces a list of tables contained within an MDB database in a format suitable for use in shell scripts.

OPTIONS

       -S     Show system tables. System tables are generally those beginning with 'MSys'

       -1     specifies that the tables should be listed 1 per line.

       -d delimiter
	      specifies an alternative delimiter. If no delimiter is specified, table names will be delimited by a tab character, or by newline if
	      the -1 option was specified.

NOTES

ENVIRONMENT

       MDB_JET3_CHARSET
	      Defines the charset of the input JET3 (access 97) file. Default is CP1252. See iconv(1).

       MDBICONV
	      Defines the output charset. Default is UTF-8. mdbtools must have been compiled with iconv.

       MDBOPTS
	      semi-column separated list of options:

	      o  use_index

	      o  no_memo

	      o  debug_like

	      o  debug_write

	      o  debug_usage

	      o  debug_ole

	      o  debug_row

	      o  debug_props

	      o  debug_all is a shortcut for all debug_* options

HISTORY

       mdb-tables first appeared in MDB Tools 0.3.

AUTHORS

       The mdb-tables utility was written by Brian Bruns.

BUGS

       Access allows for tables to have spaces embeded in the table name.
	      You must specify a delimiter (-d) if you intend on piping the output of mdb-tables to a program such as awk or cut.
