Please help with a Find and Replace using Perl Regex and back references.
I get the unexpected output as shown in the 2nd screenshot.
I am expecting/wating to get rid of everything after the first 3 CSV entries

Many thanks for nay reply

\001\002\003 is wrong, needs to be

Code: Select all

$1$$2$$3$

ie $1$ followed by $2$ etc

Fantastic! Thank you. Works a treat. Should I have seen this in the notes/help somewhere? Thanks again

But why not use a CSV replace filter?

Simpler to understand & maintain.
