How to simplify this google sheets regex sequence? - regex

I want to make the following transformation to a set of datas in my google spreadsheets :
6 views -> 6
73K views -> 73000
3650 -> 3650
163K views -> 163000
1.2K views -> 1200
52.5K -> 52500
All the datas are in a column and depending on the case I need to apply a specific transformation.
I tried to put all the regex in one formula but I failed. I always had a case over two regular expressions etc.
Anyaway I end up making these regex one case by one case in different columns. It works fine but I feel like it could slowdown the sheet since I except a lot of data coming into this sheet.
Here is the sheet : spreadsheet
Thank you for your help !

Use regexreplace(), like this:
=arrayformula(
iferror( 1 /
value(
regexreplace(
regexreplace(trim(A2:A), "\s*K", "e3"),
" views", ""
)
)
^ -1 )
)
See your sample spreadsheet.

replace 'views' using regex: /(?<=(\d*\.?\d+\K?)) views/gi
To replace 'K' with or without decimal value, first, detect K then replace K with an empty string and multiply by 1000.
use call back function as:
txt.replace(/(?<=(\d*\.?\d+\K?)) views/gi, '').replace(/(?<=\d)\.?\d+K/g, x => x.replace(/K/gi, '')*1000)
code:
arr = [`6 views`,
`73K views`,
`3650`,
`163K views`,
`1.2K views`,
`52.5K`];
arr.forEach(txt => {
console.log(txt.replace(/(?<=(\d*\.?\d+\K?)) views/gi, '').replace(/(?<=\d)\.?\d+K/g, x => x.replace(/K/gi, '')*1000))
})
Output:
6
73000
3650
163000
1200
52500

Say your inputs are in column A. Empty cells allowed. In any other column,
=arrayformula(if(A2:A<>"",value(substitute(substitute(A2:A," views",""),"K","e3")),))
works.
Adjust the range A2:A as needed.
Also note that non-empty cells with empty strings are ignored.
Basically, since Google Sheet's regex engine doesn't support look around, it is more efficient to take advantage of the rather strict patterns in your application and use substitute() instead.

Google Sheets: How can I extract partial text from a string based on a column of different options?

Goal: I have a bunch of keywords I'd like to categorise automatically based on topic parameters I set. Categories that match must be in the same column so the keyword data can be filtered.
e.g. If I have "Puppies" as a first topic, it shouldn't appear as a secondary or third topic otherwise the data cannot be filtered as needed.
Example Data: https://docs.google.com/spreadsheets/d/1TWYepApOtWDlwoTP8zkaflD7AoxD_LZ4PxssSpFlrWQ/edit?usp=sharing
Video: https://drive.google.com/file/d/11T5hhyestKRY4GpuwC7RF6tx-xQudNok/view?usp=sharing
Parameters Tab: I will add words in columns D-F that change based on the keyword data set and there will often be hundreds, if not thousands, of options for larger data sets.
Categories Tab: I'd like to have a formula or script that goes down the columns D-F in Parameters and fills in a corresponding value (in Categories! columns D-F respectively) based on partial match with column B or C (makes no difference to me if there's a delimiter like a space or not. Final data sheet should only have one of these columns though).
Things I've Tried:
I've tried a bunch of things. Nested IF formula with regexmatch works but seems clunky.
e.g. this formula in Categories! column D
=IF(REGEXMATCH($B2,LOWER(Parameters!$D$3)),Parameters!$D$3,IF(REGEXMATCH($B2,LOWER(Parameters!$D$4)),Parameters!$D$4,""))
I nested more statements changing out to the next cell in Parameters!D column (as in , manually adding $D$5, $D$6 etc) but this seems inefficient for a list thousands of words long. e.g. third topic will get very long once all dog breed types are added.
Any tips?
Functionality I haven't worked out:
if a string in Categories B or C contains more than one topic in the parameters I set out, is there a way I can have the first 2 to show instead of just the first one?
e.g. Cell A14 in Categories, how can I get a formula/automation to add both "Akita" & "German Shepherd" into the third topic? Concatenation with a CHAR(10) to add to new line is ideal format here. There will be other keywords that won't have both in there in which case these values will just show up individually.
Since this data set has a bunch of mixed breeds and all breeds are added as a third topic, it would be great to differentiate interest in mixes vs pure breeds without confusion.
Any ideas will be greatly appreciated! Also, I'm open to variations in layout and functionality of the spreadsheet in case you have a more creative solution. I just care about efficiently automating a tedious task!!
Try using custom function:
To create custom function:
1.Create or open a spreadsheet in Google Sheets.
2.Select the menu item Tools > Script editor.
3.Delete any code in the script editor and copy and paste the code below into the script editor.
4.At the top, click Save save.
To use custom function:
1.Click the cell where you want to use the function.
2.Type an equals sign (=) followed by the function name and any input value — for example, =DOUBLE(A1) — and press Enter.
3.The cell will momentarily display Loading..., then return the result.
Code:
function matchTopic(p, str) {
var params = p.flat(); //Convert 2d array into 1d
var buildRegex = params.map(i => '(' + i + ')').join('|'); //convert array into series of capturing groups. Example (Dog)|(Puppies)
var regex = new RegExp(buildRegex,"gi");
var results = str.match(regex);
if(results){
// The for loops below will convert the first character of each word to Uppercase
for(var i = 0 ; i < results.length ; i++){
var words = results[i].split(" ");
for (let j = 0; j < words.length; j++) {
words[j] = words[j][0].toUpperCase() + words[j].substr(1);
}
results[i] = words.join(" ");
}
return results.join(","); //return with comma separator
}else{
return ""; //return blank if result is null
}
}
Example Usage:
Parameters:
First Topic:
Second Topic:
Third Topic:
Reference:
Custom Functions
I've added a new sheet ("Erik Help") with separate formulas (highlighted in green currently) for each of your keyword columns. They are each essentially the same except for specific column references, so I'll include only the "First Topic" formula here:
=ArrayFormula({"First Topic";IF(A2:A="",,IFERROR(REGEXEXTRACT(LOWER(B2:B&C2:C),JOIN("|",LOWER(FILTER(Parameters!D3:D,Parameters!D3:D<>""))))) & IFERROR(CHAR(10)&REGEXEXTRACT(REGEXREPLACE(LOWER(B2:B&C2:C),IFERROR(REGEXEXTRACT(LOWER(B2:B&C2:C),JOIN("|",LOWER(FILTER(Parameters!D3:D,Parameters!D3:D<>""))))),""),JOIN("|",LOWER(FILTER(Parameters!D3:D,Parameters!D3:D<>""))))))})
This formula first creates the header (which can be changed within the formula itself as you like).
The opening IF condition leaves any row in the results column blank if the corresponding cell in Column A of that row is also blank.
JOIN is used to form a concatenated string of all keywords separated by the pipe symbol, which REGEXEXTRACT interprets as OR.
IFERROR(REGEXEXTRACT(LOWER(B2:B&C2:C),JOIN("|",LOWER(FILTER(Parameters!D3:D,Parameters!D3:D<>""))))) will attempt to extract any of the keywords from each concatenated string in Columns B and C. If none is found, IFERROR will return null.
Then a second-round attempt is made:
& IFERROR(CHAR(10)&REGEXEXTRACT(REGEXREPLACE(LOWER(B2:B&C2:C),IFERROR(REGEXEXTRACT(LOWER(B2:B&C2:C),JOIN("|",LOWER(FILTER(Parameters!D3:D,Parameters!D3:D<>""))))),""),JOIN("|",LOWER(FILTER(Parameters!D3:D,Parameters!D3:D<>"")))))
Only this time, REGEXREPLACE is used to replace the results of the first round with null, thus eliminating them from being found in round two. This will cause any second listing from the JOIN clause to be found, if one exists. Otherwise, IFERROR again returns null for round two.
CHAR(10) is the new-line character.
I've written each of the three formulas to return up to two results for each keyword column. If that is not your intention for "First Topic" and "Second Topic" (i.e., if you only wanted a maximum of one result for each of those columns), just select and delete the entire round-two portion of the formula shown above from the formula in each of those columns.

Regex (re2 googlesheets) multiple values in multiline cell

Getting stuck on how to read and pretty up these values from a multiline cell via arrayformula.
Im using regex as preceding line can vary.
just formulas please, no custom code
The first column looks like a set of these:
```
[config]
name = the_name
texture = blah.dds
cost = 1000
[effect0]
value = 1000
type = ATTR_A
[effect1]
value = 8
type = ATTR_B
[feature0]
name = feature_blah
[components]
0 = comp_one,1
[resources]
res_one = 1
res_five = 1
res_four = 1
<br/>
Where to be useful elsewhere, at minimum it needs each [tag] set ([effect\d], [feature\d], ect) to be in one column each, for example the 'effects' column would look like:
ATTR_A:1000,ATTR_B:8
and so on.
Desired output can also be seen in the included spreadsheet
<br/>
<b>Here is the example spreadsheet:</b>
https://docs.google.com/spreadsheets/d/1arMaaT56S_STTvRr2OxCINTyF-VvZ95Pm3mljju8Cxw/edit?usp=sharing
**Current REGEXREPLACE**
Kinda works, finds each 'type' and 'value' great, just cant figure out how to extract just that from the rest, tried capture (and non-capturing) groups before and after but didnt work
=ARRAYFORMULA(REGEXREPLACE($A3:$A,"[\n.][effect\d][\n.](.)\n(.)","1:$1 2:$2"))
**Current SUBSTITUTE + REGEXEXTRACT + REGEXREPLACE**
A different approach entirely, also kinda works, longer form though and left with having to parse the values out of that string, where got stuck again. Idea was to use this to simplify, then regexreplace like above. Getting stuck removing content around the final matches though, and if can do that then above approach is fine too.
// First ran a substitute
=ARRAYFORMULA(SUBSTITUTE(SUBSTITUTE($A3:$A,char(10),";"),";;",char(10)))
// Then variation of this (gave up on single line 'effect/d' so broke it up to try and get it working)
=ARRAYFORMULA(IF(A3:A<>"",IFERROR(REGEXEXTRACT(A3:A,"(?m)^(?:[effect0]);(.)$")&";;")&""&IFERROR(REGEXEXTRACT(A3:A,"(?m)^(?:[effect1]);(.)$")&";;")&""&IFERROR(REGEXEXTRACT(A3:A,"(?m)^(?:[effect2]);(.)$")&";;"),""))
// Then use regexreplace like above
=ARRAYFORMULA(REGEXREPLACE($B3:$B,"value = (.);type = (.);;","1:$1 2:$2"))
**--EDIT--**
Also, as my updated 'Desired Output' sheet shows (see timestamped comment below), bonus kudos if you can also extract just the values of matching 'type's to those extra columns (see spreadsheet).
All good if you cant though, just realized would need that too for lookups.
**--END OF EDIT--**
<br/>
Ive tried dozens of things, discarding each in turn, had a quick look in version history to grab out two promising attempts and shared them in separate sheets.
One of these also used SUBSTITUTE to simplify input column, im happy for a solution using either RAW or the SUBSTITUTE results.

<b>Just some more words:</b>
I also have looked at dozens of stackoverflow and google support pages, so tried both REGEXEXTRACT and REGEXREPLACE, both promising but missing that final tweak. And i tried dozens of tweaks already on both.
Any help would be great, and hopefully help others in future since examples with spreadsheets are great since every new REGEX seems to be a new adventure ;)

This was a fun exercise. :-)
Caveat first: I have added some "input data". Examples:
[feature1]
name = feature_active_spoiler2
[components]
0 = spoiler,1
1 = spoilerA, 2
So the output has "extra" output.

Exact match of string in pandas python

I have a column in data frame which ex df:
A
0 Good to 1. Good communication EI : tathagata.kar#ae.com
1 SAP ECC Project System EI: ram.vaddadi#ae.com
2 EI : ravikumar.swarna Role:SSE Minimum Skill
I have a list of of strings
ls=['tathagata.kar#ae.com','a.kar#ae.com']
Now if i want to filter out
for i in range(len(ls)):
df1=df[df['A'].str.contains(ls[i])
if len(df1.columns!=0):
print ls[i]
I get the output
tathagata.kar#ae.com
a.kar#ae.com
But I need only tathagata.kar#ae.com
How Can It be achieved?
As you can see I've tried str.contains But I need something for extact match
You could simply use ==
string_a == string_b
It should return True if the two strings are equal. But this does not solve your issue.
Edit 2: You should use len(df1.index) instead of len(df1.columns). Indeed, len(df1.columns) will give you the number of columns, and not the number of rows.
Edit 3: After reading your second post, I've understood your problem. The solution you propose could lead to some errors.
For instance, if you have:
ls=['tathagata.kar#ae.com','a.kar#ae.com', 'tathagata.kar#ae.co']
the first and the third element will match str.contains(r'(?:\s|^|Ei:|EI:|EI-)'+ls[i])
And this is an unwanted behaviour.
You could add a check on the end of the string: str.contains(r'(?:\s|^|Ei:|EI:|EI-)'+ls[i]+r'(?:\s|$)')
Like this:
for i in range(len(ls)):
df1 = df[df['A'].str.contains(r'(?:\s|^|Ei:|EI:|EI-)'+ls[i]+r'(?:\s|$)')]
if len(df1.index != 0):
print (ls[i])
(Remove parenthesis in the "print" if you use python 2.7)
Thanks for the help. But seems like I found a solution that is working as of now.
Must use str.contains(r'(?:\s|^|Ei:|EI:|EI-)'+ls[i])
This seems to solve the problem.
Although thanks to #IsaacDj for his help.
Why not just use:
df1 = df[df['A'].[str.match][1](ls[i])
It's the equivalent of regex match.

cts:value-match on xs:dateTime() type in Marklogic

I have a variable $yearMonth := "2015-02"
I have to search this date on an element Date as xs:dateTime.
I want to use regex expression to find all files/documents having this date "2015-02-??"
I have path-range-index enabled on ModifiedInfo/Date
I am using following code but getting Invalid cast error
let $result := cts:value-match(cts:path-reference("ModifiedInfo/Date"), xs:dateTime("2015-02-??T??:??:??.????"))
I have also used following code and getting same error
let $result := cts:value-match(cts:path-reference("ModifiedInfo/Date"), xs:dateTime(xs:date("2015-02-??"),xs:time("??:??:??.????")))
Kindly help :)
It seems you are trying to use wild card search on Path Range index which has data type xs:dateTime().
But, currently MarkLogic don't support this functionality. There are multiple ways to handle this scenario:
You may create Field index.
You may change it to string index which supports wildcard search.
You may run this workaround to support your existing system:
for $x in cts:values(cts:path-reference("ModifiedInfo/Date"))
return if(starts-with(xs:string($x), '2015-02')) then $x else ()
This query will fetch out values from lexicon and then you may filter your desired date.
You can solve this by combining a couple cts:element-range-querys inside of an and-query:
let $target := "2015-02"
let $low := xs:date($target || "-01")
let $high := $low + xs:yearMonthDuration("P1M")
return
cts:search(
fn:doc(),
cts:and-query((
cts:element-range-query("country", ">=", $low),
cts:element-range-query("country", "<", $high)
))
)
From the cts:element-range-query documentation:
If you want to constrain on a range of values, you can combine multiple cts:element-range-query constructors together with cts:and-query or any of the other composable cts:query constructors, as in the last part of the example below.
You could also consider doing a cts:values with a cts:query param that searches for values between for instance 2015-02-01 and 2015-03-01. Mind though, if multiple dates occur within one document, you will need to post filter manually after all (like in option 3 of Navin), but it could potentially speed up post-filtering a lot..
HTH!

Stata: Efficient way to replace numerical values with string values

I have code that currently looks like this:
replace fname = "JACK" if id==103
replace lname = "MARTIN" if id==103
replace fname = "MICHAEL" if id==104
replace lname = "JOHNSON" if id==104
And it goes on for multiple pages like this, replacing an ID name with a first and last name string. I was wondering if there is a more efficient way to do this en masse, perhaps by using the recode command?
I will echo the other answers that suggest a merge is the best way to do this.
But if you absolutely must code the lines item-wise (again, messy) you can generate a long list ("pages") of replace commands by using MS Excel to "help" you write the code. Here is a picture of your Excel sheet with one example, showing the MS Excel formula:
columns:
A B C D
row: 1 last first id code
2 MARTIN JACK 103 ="replace fname=^"&B2&"^ if id=="&C2
You type that in, make sure it looks like Stata code when the formula calculates (aside from the carets), and copy the formula in column D down to the end of your list. Then copy the whole block of Stata code in column D generated by the formulas into your do-file, and do a find and replace (be careful here if you are using the caret elsewhere for mathematical uses!!) for all ^ to be replaced with ", which will end up generating proper Stata syntax.
(This is truly a brute force way of doing this, and is less dynamic in the case that there are subsequent changes to your generation list. All--apologies in advance for answering a question here advocating use of Excel :) )
You don't explain where the strings you want to add come from, but what is generally the best technique is explained at
http://www.stata.com/support/faqs/data-management/group-characteristics-for-subsets/index.html
Create an associative array of ids vs Fname,Lname
103 => JACK,MARTIN
104 => MICHAEL,JOHNSON
...
Replace
id => hash{id} ( fname & lname )
The efficiency of doing this will be taken care by the programming language used
