Whether you use utilities like cut and others to define where dilimiters go, you're still faced with the same problem of defining the column positions in numeric terms. And, unless you have control of the data feed and you can define delimieters, you're stuck mapping one way or the other.
If you have TOAD (gag!) at your disposal, one of its two nice features enable you to map this a little easier.
Besides, the positioning format is somewhat easier to read.
eg:
It doesn't offer much help with delimiters but you can read it versus "Fields terminated by ";" Optionally enclosed by '"'". Also, you don't have any issues with quotations mucking things up.

pr - convert text files for printing
SYNOPSIS
pr [OPTION]... [FILE]...
DESCRIPTION
Paginate or columnate FILE(s) for printing.
With no FILE, or when FILE is -, read standard input.
Mandatory arguments to long options are mandatory for short options too.
+FIRST_PAGE[:LAST_PAGE], --pages=FIRST_PAGE[:LAST_PAGE]
begin [stop] printing with page FIRST_[LAST_]PAGE
-COLUMN, --columns=COLUMN
output COLUMN columns and print columns down, unless -a is used. Balance number of lines in the columns on each page
-a, --across
print columns across rather than down, used together with -COLUMN
-c, --show-control-chars
use hat notation (^G) and octal backslash notation
-d, --double-space
double space the output
-D, --date-format=FORMAT
use FORMAT for the header date
-e[CHAR[WIDTH]], --expand-tabs[=CHAR[WIDTH]]
expand input CHARs (TABs) to tab WIDTH (8)
-F, -f, --form-feed
use form feeds instead of newlines to separate pages (by a 3-line page header with -F or a 5-line header and trailer without -F)
-h, --header=HEADER
use a centered HEADER instead of filename in page header, -h "" prints a blank line, don't use -h""
-i[CHAR[WIDTH]], --output-tabs[=CHAR[WIDTH]]
replace spaces with CHARs (TABs) to tab WIDTH (8)
-J, --join-lines
merge full lines, turns off -W line truncation, no column alignment, --sep-string[=STRING] sets separators
-l, --length=PAGE_LENGTH
set the page length to PAGE_LENGTH (66) lines (default number of lines of text 56, and with -F 63). implies -t if PAGE_LENGTH <= 10
-m, --merge
print all files in parallel, one in each column, truncate lines, but join lines of full length with -J
-n[SEP[DIGITS]], --number-lines[=SEP[DIGITS]]
number lines, use DIGITS (5) digits, then SEP (TAB), default counting starts with 1st line of input file
-N, --first-line-number=NUMBER
start counting with NUMBER at 1st line of first page printed (see +FIRST_PAGE)
-o, --indent=MARGIN
offset each line with MARGIN (zero) spaces, do not affect -w or -W, MARGIN will be added to PAGE_WIDTH
-r, --no-file-warnings
omit warning when a file cannot be opened
-s[CHAR], --separator[=CHAR]
separate columns by a single character, default for CHAR is the <TAB> character without -w and 'no char' with -w. -s[CHAR] turns
off line truncation of all 3 column options (-COLUMN|-a -COLUMN|-m) except -w is set
-S[STRING], --sep-string[=STRING]
separate columns by STRING, without -S: Default separator <TAB> with -J and <space> otherwise (same as -S" "), no effect on column
options
-t, --omit-header
omit page headers and trailers; implied if PAGE_LENGTH <= 10
-T, --omit-pagination
omit page headers and trailers, eliminate any pagination by form feeds set in input files
-v, --show-nonprinting
use octal backslash notation
-w, --width=PAGE_WIDTH
set page width to PAGE_WIDTH (72) characters for multiple text-column output only, -s[char] turns off (72)
-W, --page-width=PAGE_WIDTH
set page width to PAGE_WIDTH (72) characters always, truncate lines, except -J option is set, no interference with -S or -s
--help display this help and exit
--version
output version information and exit
