It's somewhat difficult to follow the thread, but.... I think I understand what you're after.
Usually you don't to store ALL the records, but rather one record per key - where the 'key' is your 'unique identifier' for the type of a record.
Awk has a notion of the 'associative arrays' - very similar to perl's hashes. You can store by a 'key', update by a 'key' and lookup by a 'key'.
You can process your CSV once, store the relative pieces of a file in the array, manipulate the array cells as you go AND post-process the content of the array in the awk's 'END' session [by iterating through the array: for( i in array)].
The associative arrays are dynamic in nature and their size is bound only by the available memory. Seems like you don't have huge files to process - you should be ok.

XkbKeySymEntry(3) XKB FUNCTIONS XkbKeySymEntry(3)
NAME
XkbKeySymEntry - Returns the keysym corresponding to shift level shift and group grp from the two-dimensional array of keysyms for the key
corresponding to keycode
SYNOPSIS
KeySym XkbKeySymEntry macro ( xkb, keycode, shift, grp )
XkbDescPtr xkb;
KeyCode keycode;
int shift;
int grp;
ARGUMENTS
- xkb Xkb description of interest
- keycode
keycode of interest
- shift
shift level of interest
- grp group of interest
DESCRIPTION
The key width and number of groups associated with a key are used to form a small two-dimensional array of KeySyms for a key. This array
may be different sizes for different keys. The array for a single key is stored as a linear list, in row-major order. The arrays for all of
the keys are stored in the syms field of the client map. There is one row for each group associated with a key and one column for each
level. The index corresponding to a given group and shift level is computed as:
idx = group_index * key_width + shift_level
The offset field of the key_sym_map entry for a key is used to access the beginning of the array.
XkbKeySymEntry returns the keysym corresponding to shift level shift and group grp from the two-dimensional array of keysyms for the key
corresponding to keycode.
