The problem doing this in bash is that every single value needs to be stored in order to do this, shell memory can be limited in size, and proper two-dimensional arrays aren't available. awk is probably better suited.

writing something.

I presume this is 'battleship' style notation, row then column then value? Are they always in order like that, AA, AB, AC, BA, BB, BC... Are they actually characters, or are they longer strings? Is the number of rows and columns known?

COLUMN(1)						    BSD General Commands Manual 						 COLUMN(1)

NAME
column -- columnate lists SYNOPSIS
column [-ntx] [-c columns] [-s sep] [file ...] DESCRIPTION
The column utility formats its input into multiple columns. Rows are filled before columns. Input is taken from file operands, or, by default, from the standard input. Empty lines are ignored. The options are as follows: -c Output is formatted for a display columns wide. -s Specify a set of characters to be used to delimit columns for the -t option. -t Determine the number of columns the input contains and create a table. Columns are delimited with whitespace, by default, or with the characters supplied using the -s option. Useful for pretty-printing displays. -x Fill columns before filling rows. -n By default, the column command will merge multiple adjacent delimiters into a single delimiter when using the -t option; this option disables that behavior. This option is a Debian GNU/Linux extension. ENVIRONMENT
The COLUMNS, LANG, LC_ALL and LC_CTYPE environment variables affect the execution of column as described in environ(7). EXIT STATUS
The column utility exits 0 on success, and >0 if an error occurs. EXAMPLES
(printf "PERM LINKS OWNER GROUP SIZE MONTH DAY " ; printf "HH:MM/YEAR NAME " ; ls -l | sed 1d) | column -t SEE ALSO
colrm(1), ls(1), paste(1), sort(1) HISTORY
The column command appeared in 4.3BSD-Reno. BUGS
Input lines are limited to LINE_MAX (2048) bytes in length. BSD
