I'm encountering an error when typing out a DAX formula in a new column. The idea is to see if one of multiple criteria are true, and as part of that I am testing which formulas to use.
When trying to see if someone's name appears in a different column, I took two approaches:
ColumnName = 'Lead'[User.Name] = "John Smith"
and
ColumnName = SEARCH("John Smith",'Lead'[User.Name])
In the first case it correctly finds John Smith. In the second case I get an error: "The search Text provided to function 'SEARCH' could not be found in the given text. This is a problem as I'm hoping to use SEARCH for a partial match on another column.
If I expand the SEARCH formula by including the start position and/or criteria for value not found it doesn't fix the issue.
Am I doing something wrong?
OK, was doing something wrong. Should have used formula:
ColumnName = SEARCH("John Smith",'Lead'[User.Name],,0)

I'm using some VLOOKUPs to pull in text from another tab on my spreadsheet using the below formula
={"Product Category Test";ARRAYFORMULA(IF(ISBLANK(A2:A),"",
VLOOKUP(A2:A,'Import Template'!A:DB,MATCH("Product Category",'Import
Template'!A1:DB1,0),false)&"|"&IF(VLOOKUP(A2:A,'Import Template'!A:DB,MATCH("Automatic
Categories",'Import Template'!A1:DB1,0),false)<>"",VLOOKUP(A2:A,'Import
Template'!A:DB,MATCH("Automatic Categories",'Import Template'!A1:DB1,0),false),"")))}
Example of results: Books|Coming Soon Images|
All of my results will be delimited by a "|" which will also be the final character. I need to remove the final "|" from the results ideally without using a helper column, is there a way to wrap another function around my formula to achieve this? I've played around with RIGHT and LEN but can't figure it out.
Thanks,
use regex:
=ARRAYFORMULA({"Product Category Test"; REGEXREPLACE(""&IF(ISBLANK(A2:A),,
VLOOKUP(A2:A,'Import Template'!A:DB,MATCH("Product Category",'Import
Template'!A1:DB1,0),)&"|"&IF(VLOOKUP(A2:A,'Import Template'!A:DB,MATCH("Automatic
Categories",'Import Template'!A1:DB1,0), )<>"",VLOOKUP(A2:A,'Import
Template'!A:DB,MATCH("Automatic Categories",'Import Template'!A1:DB1,0),),)), "\|$", )})
if this won't work make sure there are no empty spaces after last |
I need to create some columns from a cell that contains text separated by "_".
The input would be:
campaign1_attribute1_whatever_yes_123421
And the output has to be in different columns (one per field), with no "_" and excluding the final number, as it follows:
campaign1 attribute1 whatever yes
It must be done using a regex formula!
help!
Thanks in advance (and sorry for my english)
=REGEXEXTRACT("campaign1_attribute1_whatever_yes_123421","(("®EXREPLACE("campaign1_attribute1_whatever_yes_123421","((_)|(\d+$))",")$1(")&"))")
What this does is replace all the _ with parenthesis to create capture groups, while also excluding the digit string at the end, then surround the whole string with parenthesis.
We then use regex extract to actuall pull the pieces out, the groups automatically push them to their own cells/columns
To solve this you can use the SPLIT and REGEXREPLACE functions
Solution:
Text - A1 = "campaign1_attribute1_whatever_yes_123421"
Formula - A3 = =SPLIT(REGEXREPLACE(A1,"_+\d*$",""), "_", TRUE)
Explanation:
In cell A3 We use SPLIT(text, delimiter, [split_by_each]), the text in this case is formatted with regex =REGEXREPLACE(A1,"_+\d$","")* to remove 123421, witch will give you a column for each word delimited by ""
A1 = "campaign1_attribute1_whatever_yes_123421"
A2 = "=REGEXREPLACE(A1,"_+\d*$","")" //This gives you : *campaign1_attribute1_whatever_yes*
A3 = SPLIT(A2, "_", TRUE) //This gives you: campaign1 attribute1 whatever yes, each in a separate column.
I finally figured it out yesterday in stackoverflow (spanish): https://es.stackoverflow.com/questions/55362/c%C3%B3mo-separo-texto-por-guiones-bajos-de-una-celda-en...
It was simple enough after all...
The reason I asked to be only in regex and for google sheets was because I need to use it in Google data studio (same regex functions than spreadsheets)
To get each column just use this regex extract function:
1st column: REGEXP_EXTRACT(Campaña, '^(?:[^_]*_){0}([^_]*)_')
2nd column: REGEXP_EXTRACT(Campaña, '^(?:[^_]*_){1}([^_]*)_')
3rd column: REGEXP_EXTRACT(Campaña, '^(?:[^_]*_){2}([^_]*)_')
etc...
The only thing that has to be changed in the formula to switch columns is the numer inside {}, (column number - 1).
If you do not have the final number, just don't put the last "_".
Lastly, remember to do all the calculated fields again, because (for example) it gets an error with CPC, CTR and other Adwords metrics that are calculated automatically.
Hope it helps!
How can I use regular expression in excel ?
In above image I have column A and B. I have some values in column A. Here I need to move data after = in column B. For e.g. here in 1st row I have SELECT=Hello World. Here I want to remove = sign and move Hello world in column B. How can I do such thing?
Stackoverflow has many posts about adding regular expressions to Excel using VBA. For your particular example, you would need VBA to actually move a substring from one cell to another.
If you simply want to copy the substring, you can do so easily using the MID function:
=IFERROR(MID(A1,FIND("=",A1)+1,999),A1)
I used 999 to ensure that enough characters were grabbed.
IFERROR returns the cell as-is if an equals sign is not found.
To return the portion of string before the equals sign, do this:
=LEFT(A1,FIND("=",A1&"=")-1)
In this case, I appended the equals sign to A1, so FIND won't return an error if not found.
You can use the Text to Column functionality of MS-Excel giving '=' as delimiter.
Refer to this link:
Chop text in column to 60 charactersblocks
You can simply use Text to Column feature of excel for this:
Follow the below steps :
1) Select Column A.
2) Goto Data Tab in Menu Bar.
3) Click Text to Column icon.
4) Choose Delimited option and do Next and then check the Other options in delimiter and enter '=' in the entry box.
5) Just click finish.
Here are URL for Text to Column : http://www.excel-easy.com/examples/text-to-columns.html
I have a xpath expression which I want to use to extract City and date from a td which contains a string of this kind:
City(may contain spaces and may be missing, but the following space is always present) on 2013/07/20
So far, I got to the following solution for extracting the date, which works partially:
//path/to/my/td/text()/replace(.,'(.*) on (.*)','$3')
This works when City is present, but when City is missing I get "on 2013/07/20" as a result.
I think this is because the first capturing group fails and so the number of groups is different.
How can I get this expression to work?
I did not fully check your regex, but it looks fine at first sight. Anyway, you can also go an easier way if you only want to get the date by extracting the text after "on ":
//path/to/my/td/text()/substring-after(.,'on ')
edit: or you may go the substring-way and select the last 10 characters of the content:
//path/to/my/td/text()/substring(., string-length(.) - 9)
Earlier I got some help as to how to make a script that will extract hashtags from a list of tweets and put them into an array of cells.
I used this as my code, inside a for loop
hashtagCell{i} = regexp(textRead{i}, '#[A-z]*', 'match');
This works for what it is supposed to do, but now I'm trying to find the average character length of the hashtags, so I need to be able to add the character length of each hashtag pulled out by the above function and add them together. However, when I try to use the size() function, it just gives me the size of the cell instead of the size of the strings, which is what I want. I can't figure out how to do this.
For a single string it would be like this:
%# example string with hashtags.
MyText = 'this is a #text with #hashtag and also #another hashtag';
%# create the hashtagCell.
hashtagCell = regexp(MyText, '#[A-z]*', 'match');
%# compute the mean.
AverageLength = mean(cellfun(#(x) size(x,2), hashtagCell));
This should help (and it gets rid of any loops, other than, perhaps, the one used to create CellOfText):
%# Example cell array of tweets
CellOfText = {'Bah #humbug says #Mr scrooge'; 'No #presents for you'};
%# Get all hash tags
HTC = regexp(CellOfText, '#[A-z]*', 'match');
%# Get the average hash tag length, being careful to unnest HTC
AvgLength1 = mean(cellfun('length', [HTC{:}]));
DISCLAIMER: The inspiration for this method came from this excellent answer to a similar question. Thanks to #Andrey for that.
