Are there services for reformatting csv?

Question

csv

I am looking for an online service that can reformat / convert one csv to another, I will explain
at the input we load csv 1 with columns:
title
unnecessary field
unnecessary field
description {key:value|key2:value}
at the output we get csv 2 with columns:
title
description
key
key2
that is, firstly, we save only the data that we need, secondly, the value of the string can be split according to the specified separator into separate values ​​in the list, now there is a list of goods for 1000 lines with characteristics in the form of strings (color | size | season) , and manually breaking it all into separate columns is quite problematic
, maybe someone knows the existing online services for solving this problem?
