I would like to use regex in Java to substring text.
The string must be max 140 characters in all ( not counting new line/enter characters) and there might be max 4 lines
I found out how to substring 140 symbols: ^(.|\n|\r){0,140}
My question is how to add limitation for only 4 lines
and exclude new line/enter characters
Thanks for help!
This expression should do what you are looking for:
^([^\r\n]{0,140}(\r?\n|$)){4}
Try it here.

I want to receive in example regex match only 17 and 20 (skip 3 match only two match)
Depending on what you want to do, this one can be a good solution
[0-9]{2}(?!$)
It matches the groups of 2 digits not at the end of a line !
You can also try : ([0-9]{2})\s[A-z]+\s([0-9]{2}) if you want only 2 groups

or

and so on.
I tried \S{683} but it's too large sample so I need exclude repetition of characters and have their mandatory diversity to escape matching with "aaaaaaaaaa..." or "0000000000..."
Please help if someone has it. Thanks!
If you want to match only when the entire string is exactly 683 characters and contains only valid base64 characters, use:
^[a-zA-Z0-9_\-=]{683}$

The program contains text of this type:
A B Ccccc
A Ccccc
ACcccc
ABCcccc
I need only such text to remain:
Ccccc
I wrote a replacement function, but I just can’t pick up a pattern
How to make such a pattern?
No need for regex, nor VBA. It seems you simply are looking for the position of the last upper-case letter and then to extract from there:
Formula in B1 (with Excel O365):
=MID(A1,MAX(SEQUENCE(LEN(A1))*(EXACT(UPPER(MID(A1,SEQUENCE(LEN(A1)),1)),MID(A1,SEQUENCE(LEN(A1)),1)))),LEN(A1))
If you don't have Excel O365:
=MID(A1,MAX(ROW(A1:INDEX(A:A,LEN(A1)))*(EXACT(UPPER(MID(A1,ROW(A1:INDEX(A:A,LEN(A1))),1)),MID(A1,ROW(A1:INDEX(A:A,LEN(A1))),1)))),LEN(A1))
You probably need to enter as array through: CtrlShiftEnter
If you must go through VBA and regex then a pattern like:
[A-Z][^A-Z]*$

How do you find the first word after a string literal via regex?
I.e.
I want to extract "DAQJ7PS" from the line:
ERROR service.PostService - Failed to save post DAQJ7PS
/ERROR service\.PostService - Failed to save post (.+)/
will give you the result in the first capturing group. This can be tuned if you have more specific requirements.
