Find and replace encoded urls in files


I have several hundred markdown files.
Each one of the has a portion of the text in it,that contains an encoded url.

Is there any way I can use Search and replace,a command maybe to look up for all the encoded urls and auto decode them?
Thank you.


You can write your own command to do that. How comfortable are you with JavaScript or CoffeeScript, and with Node.js?


A bit JS only.These days I am expanding,learning a bit more through udemy courses.
I guess it isnt that easy?
