I'm having trouble getting a REGEXREPLACE working in a Google Sheets formula. I'm aiming to replicate a certain card game which is opposed to humankind. I have a cell containing a string which contains one, two or three occurrences of a series of underscores, e.g.
"_____ is the new _____"
And let's say I want to substitute in the strings "Orange" for the first occurrence, and "Black" for the second occurrence.
I don't know how many underscores will be in each string, it could be one or more, so it seems like a job for regex. I tried SUBSTITUTE and it didn't seem to recognise asterisks. Based on this link, I tried using {1} {2} and {3} to match the first/second/third occurrence, but I'm not doing something right:
=REGEXREPLACE(G16,".*(_*){1}.*",G17)
G16 is: _____ is the new _____.
G17 is: Orange
The output of the formula is: OrangeOrange.
Can anyone help me figure out the correct way to do this?
You may use
=REGEXREPLACE(REGEXREPLACE(G16,"^([^_]*)_+","$1Orange"), "^([^_]*)_+", "$1Black")
|----- First occurrence -----------------|
|----------------- Second occurrence ------------------------------------------|
Details
^ - start of string
([^_]*) - Capturing group 1 ($1 will refer to this group value): 0 or more chars other than an underscore
_+ - 1 or more underscores.
I work with text files, and I need to be able to see when the gps (last 3 columns of csv) "hangs up" for more than a few lines.
So for example, usually, part of a text file looks like this:
5451,1667,180007,35.7397387,97.8161897,375.8
5448,1053z,180006,35.7397407,97.8161814,375.7
5444,1667,180005,35.7397445,97.8161674,375.6
5439,1668,180004,35.7397483,97.8161526,375.5
5435,1669,180003,35.7397518,97.8161379,375.5
5431,1669,180002,35.7397554,97.8161269,375.6
5426,1054z,180001,35.7397584,97.8161115,375.6
5420,1670,175959,35.7397649,97.8160931,375.9
But sometimes there is an error with the gps and it looks like this:
36859,1598,202603.00,35.8867316,99.2515545,555.700
36859,1598,202608.00,35.8867316,99.2515545,555.700
36859,1142z,202610.00,35.8867316,99.2515545,555.700
36859,1597,202612.00,35.8867316,99.2515545,555.700
36859,1597,202614.00,35.8867316,99.2515545,555.700
36859,1596,202616.00,35.8867316,99.2515545,555.700
36859,1595,202618.00,35.8867316,99.2515545,555.700
I need to be able to figure out a way to search for matching strings of 7 different numbers, (the decimal portion of the gps) but so far I've only been able to figure out how to search for repeating #s or consecutive numbers.
Any ideas?
If you were to find such repetitions in an editor (such as Notepad++), you could use the following regex to find 4 or more repeating lines:
([^,]+(?:,[^,]+){2})\v+(?:(?:[^,]+,){3}\1(?:\v+|$)){3,}
To go a bit into detail
([^,]+(?:,[^,]+){2})\v+ is a group consisting of one or more non-commas followed by comma and another one or more non-commas followed by a vertical space (linebreak), that is not part of the group (e.g. 1,1,1\n)
(?:[^,]+,){3} matches one or more non-commas followed by comma, three times (your columns that don't have to be considered)
\1 is a backreference to group 1, matching if it contains exactly the same as group 1
(?:\v+|$) matches either another vertical whitespaces or the end of the text
{3,} for 3 or more repetitions - increase it if you want more
Here you can see, how it works
However, if you are using any programming language to check this, I wouldn't walk on the path of regex, as checking for those repetitions can be done a lot easier. Here is one example in Python, I hope you can adopt it for your needs:
oldcoords = [0,0,0]
lines = [line.rstrip('\n') for line in open(r'C:\temp\gps.csv')]
for line in lines:
gpscoords = line.split(',')[3:6]
if gpscoords == oldcoords:
repetitions += 1
else:
oldcoords = gpscoords
repetitions = 0
if repetitions == 4: #or however you define more than a few
print(', '.join(gpscoords) + ' is repeated')
If you can use perl, and if I understood you:
perl -ne 'm/^[^,]*,[^,]*,[^,]*,([^,]*,[^,]*,[^,]*$)/g; $current_line=$1; ++$line_number; if ($prev_line==$current_line){$equals++} else {if ($equals>=6){ print "Last three fields in lines ".($line_number-$equals-1)." to ".($line_number-1)." are equals to:\n$prev_line" } ; $equals=0}; $prev_line=$current_line' < onlyreplacethiswithyourfilepath should do the trick.
Sample output:
Last three fields in lines 1 to 7 are equals to:
35.8867316,99.2515545,555.700
Last three fields in lines 16 to 22 are equals to:
37.8782116,99.7825545,572.810
Last three fields in lines 31 to 44 are equals to:
36.6868916,77.2594245,581.358
Last three fields in lines 57 to 63 are equals to:
35.5128764,71.2874545,575.631
I am a noob at regex and i've been trying to select 6 numbers from within a file and then replace those 6 numbers with the same numbers plus , new line (making a CSV obviously).
Anyway sample data is simply nonsense like this:
fafksadjlkgtjafglkj210000adsfaklgjadklgjag3600001skfjaklaj093i393593390000002sadfljafkjgakjgasafksadjlkgtjafglkj£94.00 489438adsfaklgjadklgjag7700001skfjaklaj093i393593390000002ssafksa djlkgtjafglkj000000adsfaklgjadklgjag0000001skfj aklaj093i393593£39.00900002ssafksadjlk gtjafglkj000000adsfaklgjadklgjag0000001skfjaklaj093i3935£933.90000002s
Note some of the numbers are attached to currency values as well (and some are next to it but contain a space before hand) but the end will always be 6 numbers (consider them to be random as I can't see a pattern).
So I basically need to select strings matching numerics that are six digits long or longer, if longer then it just uses the last 6 digits.
Then I will replace it with itself and a comma and new line.
I hope that makes sense, i've tried a few things without success..
Thanks, edit the closest I have is:
(\d)\d{6}(?!\d)
In the Find what: text field, type in (\d{6})(\D). In the Replace with: text field, type in $1\r\n$2. Make sure that the regular expression radio button is selected. For your input, that should yield this:

i've been trying to select 6 numbers from within a file and then replace those 6 numbers with the same numbers plus , new line
So you're basically trying to do this, right?:
Find:
(\d{6})(\D)
Replace:

How about:
Find what: (\d{6,})(?:\D*)$

I'm parsing a bunch of line items on an inventory list and while each line describes something similar, the text format was not standardized. I'm been working on a regex pattern for the past few days but I'm not having much luck with getting a pattern that can match all of my test scenarios. I hoping that someone with a lot more regex experience might be able to point out a few errors in the the pattern
Pattern To Match the palette number: \([Pp]alette [No\.\s]?#?(.*?)\),
1. Warehouse A, (Palette #91L41)
# Match Result Correct: 91L41
2. Warehouse B Palette No. 214
# Match Result Incorrect: no match
3. Warehouse Lot Storage C (Palette No. 9),
# Match Result Incorrect: o. 9 //I don't quite understand why it matches the o
4. Store Location D of Palette (Palette #1),
# Match Result Correct: 1
5. Store Location E of Palette, Empty, lot #45,
# Match Result Incorrect: no match
I've also tried to make the parenthesis optional so that it will match examples 2 and 5 but it's too greedy and included the previously mentioned lot word
Anything in brackets causes the engine to look for ONE of the provided characters. Your pattern successfully matches, for example, strings like: Palette Nabcdefg
To indicate one of different options, you'll need to use paranthesis. What you're actually looking for should look something like this: [Pp]alette (No\.?\s?|#)?(\d+?)
Though it seems highly ineffective to not standardize the pattern. Your last case for example could be completely incompatible since it seems to be capable of containing possibly any kind of input.
A little bit of explanation on matching your patterns with regular expressions. You really don't need to look for and match your parentheses ( .. ) in this case.
Let's say we want to just find any string with the word Palette that is followed with whitespace and the # symbol and capture the Palette sequence from it.
You could simply just use the following:
[Pp]alette\s+#([A-Z0-9]+)
This will result in capturing 91L41 and 1 from the matched patterns
1. Warehouse A, (Palette #91L41)
4. Store Location D of Palette (Palette #1)
Now say we want to find any string that has Palette, followed by whitespace and either a # symbol or No.
We can use a Non-capturing group for this. Non-capturing parentheses group the regex so you can apply regex operators, but do not capture anything.
So we could do something like:
[Pp]alette\s+(?:No[ .]+|#)([A-Z0-9]+)
Now this results in matching the following strings and capturing 91L41, 214, 9 and 1
1. Warehouse A, (Palette #91L41)
2. Warehouse B Palette No. 214
3. Warehouse Lot Storage C (Palette No. 9)
4. Store Location D of Palette (Palette #1)
And last if you want to match all the following strings and capture the Palette sequence.
[Pp]alette[\w, ]+(?:No[ .]+|#)([A-Z0-9]+)
See working demo and an explanation on this regular expression.
Everyone has a different way of using regular expressions, this is just one of many ways you can simply understand and accomplish this.
This should work for your case:
[Pp]alette.*?(?:No\.?|#)\s*(\w+)
This will search following types of patterns:
[Pp]alette{any_characters}No.{optonal_spaces}(alphanumeric)
[Pp]alette{any_characters}No{optonal_spaces}(alphanumeric)
[Pp]alette{any_characters}#{optonal_spaces}(alphanumeric)

I am beginner and have some problems with regexp.
Input text is : something idUser=123654; nick="Tom" something
I need extract value of idUser -> 123456
I try this:
//idUser is already 8 digits number
MatchCollection matchsID = Regex.Matches(pk.html, #"\bidUser=(\w{8})\b");
Text = matchsID[1].Value;
but on output i get idUser=123654, I need only number
The second problem is with nick="Tom", how can I get only text Tom from this expresion.
you don't show your output code, where you get the group from your match collection.
Hint: you will need group 1 and not group 0 if you want to have only what is in the parentheses.
.*?idUser=([0-9]+).*?
That regex should work for you :o)
Here's a pattern that should work:
\bidUser=(\d{3,8})\b|\bnick="(\w+)"
Given the input string:
something idUser=123654; nick="Tom" something
This yields 2 matches (as seen on rubular.com):
First match is User=123654, group 1 captures 123654
Second match is nick="Tom", group 2 captures Tom
Some variations:
In .NET regex, you can also use named groups for better readability.
If nick always appears after idUser, you can match the two at once instead of using alternation as above.
I've used {3,8} repetition to show how to match at least 3 and at most 8 digits.
API links
Match.Groups property
This is how you get what individual groups captured in a match
Use look-around
(?<=idUser=)\d{1,8}(?=(;|$))
To fix length of digits to 6, use (?<=idUser=)\d{6}(?=($|;))
