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]*$

Hello there can i have an hint about how should i write the regex code to search for the commas (,) in those values between the |'...'| pattern? i need to find the commas and replace with dots(.) , if there's a comma in there of course.
|'2,3'|;|'5,6'|;|'2,1'|;|'3'|;|'6,5'|;|'9'|;|'7'|;|'4,4'|;|'4'|;|'1,1'|
expected result:
|'2.3'|;|'5.6'|;|'2.1'|;|'3'|;|'6.5'|;|'9'|;|'7'|;|'4.4'|;|'4'|;|'1,1'|
the pattern can be also what i will write below depending on some input parameters that i am going to receive in my method:
|'2,3'|,|'5,6'|,|'2,1'|,|'3'|,|'6,5'|,|'9'|,|'7'|,|'4,4'|,|'4'|,|'1,1'|
expected result:
|'2.3'|,|'5.6'|,|'2.1'|,|'3'|,|'6.5'|,|'9'|,|'7'|,|'4.4'|,|'4'|,|'1.1'|
this why i need a pattern for this because i don't know if i will receive the string with (;) or (,) separating the values
thanks so much
Regex Pattern
Here is the pattern that you can use to search for the commas , between two numbers
(?<=[0-9]),(?=[0-9])

I am trying to filter medical words from general english words.
but most of the drugs name contains hypen in it.
pls suggest how to check in python, that a string contains only alphabets and hypen.
for example : anti-allergic
Simplest way to check string is as below, remove '-' from string and check if remaining characters are all alphabets.
test_str = 'anti-allergic'
if test_str.replace('-','').isalpha():
print('Valid string')
This can be accomplished by using regular expressions (https://docs.python.org/3/library/re.html), where a (very quick and dirty) regex could ask for all letters, a to z (and A to Z), that has a hyphen in it.
([a-zA-Z]+[-].+)
Would match the following:
suoad
ADDADA
waeewrw
omaeqweSADADSwu
iraaief
anti-allergic
ANTI-ALLERGIC
testtesttest
You can test this out yourself using https://pythex.org/.

I would like to search for everything before the string http://thepaperwall.com/wallpapers/ but not including that string.
I would also like to search for everything after .jpg but not including .jpg.
So my final string should look like this:
http://thepaperwall.com/wallpapers/cityscape/small/small_642331afcd78d0840485bb352d99b289b50e8467.jpg
How can I do this?
You can use look-behind and look-ahead to get a string position between 2 other strings:
(?<=http://thepaperwall.com/wallpapers/).*(?=\.jpg)
You need a non-capturing group:
(.*)(?:http:\/\/thepaperwall\.com\/wallpapers\/.*\.jpg)(.*)

i want to parse the values between -. but for some data like 1st url contains -- so in that case i need to get the gap only and the next one i am able to get **camry** successfully by using *(site_data,'[^-]+',1,2)*. but i want to handle the gap as well.
U=Google--undefined|http://www.google.com/urlsa=t&rct=j&q=&esrc=s&frm=1&source=web&cd=2&ved=0CFMQFjAB&url=http://www.toyota.com/tundra/features.html&ei=-zwQUvOyGIXu2QWC7oGgBg&usg=AFQjCNFQKGcr2dbDeC-0zagtYdKFEfXXzQ&bvm=bv.50768961,d.aWc
U=Bing-camry-undefined|http://www.bing.com/searchq=camry&pc=MOZI&form=MOZSBR
Please help on this.
You can extract the string along with the hyphens, and then trim the hyphens.
trim('-' from regexp_substr(site_data,'-[^-]*-'))
Alternatively, you can also use regexp_replace function.
regexp_replace(site_data,'(-([^-]*)-)|(.)','\2')

I'm having another issue where I want to extract values from a string. Please take a look.
string anotherTest = "Hello World [A12345 **(05,00,45)**] - [518.6Z] [51.5]"
I would like the result to return "A12345" "518.6Z" "51.5".
What I highlighted in bold is what I'm having issue with.
I'm using c# and I've tried [(\D?\d+.?\d+\D?)] ... which is fine if I don't have what's in parentheses.
You need to extract the first word from a [ ... ] substring. Use groups:
.*?(\[([^\[\] ]+).*?\])*
Then extract second group from all the captures (depending on your langauge)
