How can i remove a part of a line of a big log file-CodePudding

i have a 15000 lines log and i want to remove a part of every line

This a what my log looks like

15 {"level":"warn","message":"warn: Player: 819631980014075905 | Track has been started playing [\u001b[34m34mSomethingElse2\u001b[39m]"}
12 {"level":"warn","message":"warn: Player: 819631980014075905 | Track has been started playing [\u001b[34m34mSomething2\u001b[39m]"}
1 {"level":"warn","message":"warn: Player: 819631980014075905 | Track has been started playing [\u001b[34m34mSomethingElse\u001b[39m]"}
3 {"level":"warn","message":"warn: Player: 819631980014075905 | Track has been started playing [\u001b[34mSomething\u001b[39m]"}

What i want the log to look like

15 SomethingElse2
12 Something2
1 SomethingElse
3 Something

Thank you all.

I didn't completely think about just using the find/replace function of almost any text editor

The obvious candidate is of course sed. It depends a bit on what you used to display the input-lines (especially the \u001b might give some trouble), but

sed 's/\{.*34m34m//;s/.u001b.*//`

You may want to put it through the same filter that you used to display the lines.
