I am trying to find software - optimally free, which would allow me to play with regular expression in a way, that from current set of found capturing groups I would be able to setup new text, copy it and paste where I need.
I have 2 lines of text taken from somewhere (copied) and pasted into Regular expression software:
2018-09-18 Hash XY
2019-01-17 Hash AB
In search field I would search for (\d\d\d\d)-(\d\d)-(\d\d)
And somewhere in 3rd window I wanted to enter %3-%2-%1
Which would give me
Do you have any idea?
