vim RegExp(s)

%s /_find_/_replace_/gc (case-insensitive and ask for each instance)

All regexp chars need to be escaped \^, \(, \) etc

\0 full match, \1 first group, \2 second etc..

%s /^\(\s\+\)\([^:]\+\):/\1"\2":/gc - begining of line find all spaces followed by string followed by colon, replace with space + " + string +":

%s /,\(\_s\+\)]/\1}/gc - find all commas at end of line that are followed by whitespace and closing }|] IE to make a js object valid json
