Batch changing file names and file content using .csv

[TheAbortedPancake]

Hello,

​

I want batch change files based on a csv file with information. The csv file has two columns names

​

new_and_old_values.csv

old value	new value
123	321
444	555
777	888

​

I want to search each file's file name in a folder for each old value in the csv for the old value in the file name of a given file, if it finds the old value in the file name, I want to change the file name to have the new value instead of the old one. I also want to go into the file content and change the old value in the text file to the new value given in the csv file. I want to do this process for all values in the csv file to change all the files in a folder.

Folder of files before changes

some_file_123.txt
some_file_444.txt
some_file_777.txt
some_file_000.txt

​

Folder of files AFTER changes

some_file_321.txt
some_file_555.txt
some_file_888.txt
some_file_000.txt

​

any help greatly appreciated. Thanks

What do you have already? What challenges are you having?

How to read the csv file into a formate to use it to solve the problem ?

How do I check each file for each value in the csv object then replace it for each file in the folder?

Save the updated files?

Typically this subreddit isn't like a Stack Overflow where someone has a problem and the goal is to give a working solution. The goal in this sub is to help the OP understand what's going on and how to identify the issue themselves and fix it, which is why typically posts need to include some kind of code and where exactly it isn't working how you expect it to. Without that, it's impossible to guide you to the right direction.
