Retrieving Data From Text?

i have a long list of what were once file names in excel that i need to retrieve data from. i have attached an example file with 2 file names which i recomend to view while reading this request.the file has 2 spreadsheets. the first one is just the file name in the format in which i recieve it. the second one is a table that i need to fill out from the data in those file names.

i have a problem with the following columns in spreadsheet 2:

1. column C: i have the command to copy the site name as it is to this column, but what i need is for the program to read if the site name is ZANUAH or ADORA and then write only Z or A. note that these two site names have a different number of charecters in them.

2. columnd D: similar problem. i need it to read the lab name and write AL if its MAGAMA, BA if its Ben-Ari and SH if its shafir. i have the command for excel to simply copy the word, but how do i make it write the letters that represent the lab name rather than the lab name itself?

3. column E: the report number is the 6 digit number in the file name. i have the command which retrieves it, but it has trouble when the length of the number changes. its important to note that sometimes the number might contain non-numerical characters like 219641-1.

4. column O:i have the command to get the data from the parentheses next to PSD in the file name into a box. what i need is to get it to copy just the letters C or NC from the file name into this column, without the number.

5. column P: same as column O, but here i need just the number, without the C or NC.

6. column T: all i need is for it to copy the last 2 letters from the file name, which i know how to do. the problem is that since the file names come with a .pdf at the end, all i get is df. so in fact i need it to copy th 6th and the 5th letters from the end of the file name, which is above my abilities.
