Some pointers
since you say that in each file, the column no, containing the date may be different, the fist thing is that you program/script must take the file name and column number as arguments.

I would use "awk" (my favourite filter) called from a shell script by:
<Shell script> <FileName> <ColumnNo>
Within the shell script
awk 'A=$1 b=$2 {awk script} ;;;

In the example, it is the 10 th field (when separated by commas).

For each line:
-- Split the 10th filed into an array using "split" function"
-- Replace the month with the appropriate text (if .. else ..)
-- Write the first 9 fields, the rearranged 10 filed and any other fileds.
