I have a big txt file. See example below;

||0011||
||0011||
||0011||
||0011||
||0011||
||0011||
||0011||
||0011||
||0011||
||0122||
||0122||
||0122||
||0122||
||0122||
||0122||
||0122||
||0122||
||0122||
||0122||
||0232||
||0232||
||0232||
||0232||
||0232||
||0232||
||0232||
||0232||
||0232||
||0232||
||0232||

What i want to do is, i want to replace 0011 with 001112, 0122 with 012234, 0232 with 023213. My problem is, that i want to replace them in one go. I am aware of replacing them in three steps i.e, first i can replace all rows that have 0011 with 001112, similar second time i can replace rows that have 0122 with 012234 etc. Please keep in mind that there are more columns and rows in the file. Above is just an example.

Since you can't do a conditional replacement with notepad++, you can use this way:

1) add these three lines at the end of your file:

#001112
#012234
#023213

2) use this pattern and replacement:

pattern: \|\|\K(\d+)(?=\|\|[\s\S]+#\1(\d+))|(?:\r?\n#.*)+$
replace: $1$2
