Append check function with _Strict? - google-sheets

An answer in this question mentioned you can use ISDATE_STRICT in an array formula, and it worked.
I searched all over and could not find a reference to the use of _STRICT anywhere.
Does this apply to all "IS" check functions?
What exactly is it doing?

Yes, unfortunately, I also don't see any articles/documentations about this one except this.
The link above is a list of sheets formulas, we can see _STRICT on 3 formulas.
ISDATE_STRICT, ISDATETIME_STRICT, ISTIME_STRICT
The link above does answer your first question, it does not apply to all functions IS functions.
Based on their behaviors, I guess that they strictly check if the value is treated and valid as date/time/datetime in sheets itself. Simply passing string as parameter will yield FALSE.
Testing:
Note:
I have a hunch why 25:02:00 for ISTIME_STRICT is still valid for time even though it goes past 24. Sheets automatically converted that value from the inputted value 25:02 thus suggests that what sheets treats as date/time/datetime, will always yield TRUE for those functions.
To test the hypothesis above, I inputted November 31, 2021 1:00 manually and it wasn't converted into 11/31/2021 01:00:00 automatically, it was still the same cell value because it wasn't treated as datetime variable by sheets, thus returning FALSE

Getting what is in between brackets from a value

I have the following value in a cell:
May 04, 2022 (50bp)
I need only what is in between ( and ). I was thinking of using =RIGHT() but I never know how much is inm between the two brackets (so the number of characters I have to give as a parameter to RIGHT(), will differ.
What is the correct way of handling this in Google Sheets?
Use REGEXEXTRACT() function.
=REGEXEXTRACT(A1,"\((.*)\)")
To extract the text between any characters, use a formula with the MID and FIND functions despite how much is in between the two brackets.
=MID(A1,FIND("(",A1)+1,FIND(")",A1)-FIND("(",A1)-1)

Parsing Error trying to import Coinbase Pro API into Google Sheets

New to APIs in Google sheets, but I feel like I'm 95% of the way to where I'm trying to go.
I'm trying to pull crypto data into my spreadsheet to do a simple 24 hour price comparison and gauge whether the price has gone up or down, maybe use some conditional code to change the background to green or red. Simple enough. Most of the sites that offer APIs have given me various errors, though, so coinbase pro (and weirdly the deprecated gdax) have been most reliable (although I haven't ruled out that it started breaking because I'm now putting in too many call requests).
Found this as a way to get the current price of ETH, for instance:
=VALUE(SUBSTITUTE(SUBSTITUTE(INDEX(IMPORTDATA("https://api.gdax.com/products/ETH-USD/ticker"),0,2), "price:",""), """", ""))
Works like a charm. So I changed the request to target different info, specifically the 24hr stats listed on the API doc, and the first value in that section, "open" for opening price (this ensures I get the price exactly 24hrs earlier). But I got a weird parsing error using the request, which is here:
=VALUE(SUBSTITUTE(SUBSTITUTE(INDEX(IMPORTDATA("https://api.pro.coinbase.com/products/ETH-USD/stats"),0,1), "open:",""), """", ""))
I've figured out the issue, but not the solution. Google Sheets says I am pulling in text. Because the "open" (opening price) value is the first listed in the JSON code, it is pulling in the code bracket from the nested HTML/JSON code. For instance, it says I can't parse "{open" into a number. And I get the same problem in reverse when I pull the last value listed in the stats section, which is "volume_30day:"
=VALUE(SUBSTITUTE(SUBSTITUTE(INDEX(IMPORTDATA("https://api.pro.coinbase.com/products/ETH-USD/stats"),0,6), "volume_30day:",""), """", ""))
This returns an error saying "volume_30day: #}" can't be parsed, so now it is the closing bracket of the JSON code. So I can't use "open" the first item in the API 24hr stats section, or Volume_30day, which is the sixth item on that list, but items 2-5 work just fine. Seems super weird to me, but I've tested it and it is seems to be what's going on.
There must be something stupid I need to tweak here, but I don't know what it is.
Answer 1:
About =VALUE(SUBSTITUTE(SUBSTITUTE(INDEX(IMPORTDATA("https://api.pro.coinbase.com/products/ETH-USD/stats"),0,1), "open:",""), """", ""))
When I checked =SUBSTITUTE(SUBSTITUTE(INDEX(IMPORTDATA("https://api.pro.coinbase.com/products/ETH-USD/stats"),0,1), "open:",""), """", ""), the value is {open:617. I think that when by this, when VALUE is used for the value, the error occurs.
In order to retrieve the values you expect, I would like to propose to use REGEXREPLACE instead of SUBSTITUTE. The modified formula is as follows.
=VALUE(REGEXREPLACE(INDEX(IMPORTDATA("https://api.pro.coinbase.com/products/ETH-USD/stats"),0,1), "open|""|{|}|:",""))
In this modified formula, open|""|{|}|: is used as the regex. These are replaced with "".
In this case, I think that =VALUE(REGEXEXTRACT(INDEX(IMPORTDATA("https://api.pro.coinbase.com/products/ETH-USD/stats"),0,1), "\d+")) can be also used. But when I thought about your 2nd question, I thought that above formula might be useful.
Result:
Answer 2:
About =VALUE(SUBSTITUTE(SUBSTITUTE(INDEX(IMPORTDATA("https://api.pro.coinbase.com/products/ETH-USD/stats"),0,6), "volume_30day:",""), """", ""))
When I checked =SUBSTITUTE(SUBSTITUTE(INDEX(IMPORTDATA("https://api.pro.coinbase.com/products/ETH-USD/stats"),0,6), "volume_30day:",""), """", ""), the value is 7101445.64098932}. I think that when by this, when VALUE is used for the value, the error occurs.
In order to retrieve the values you expect, I would like to propose to use REGEXREPLACE instead of SUBSTITUTE. The modified formula is as follows.
=VALUE(REGEXREPLACE(INDEX(IMPORTDATA("https://api.pro.coinbase.com/products/ETH-USD/stats"),0,6), "volume_30day|""|{|}|:",""))
In this modified formula, volume_30day|""|{|}|: is used as the regex. These are replaced with "".
In this regex, it can use by replacing open of open|""|{|}|: to volume_30day at above regex.
Result:
Other pattern 1:
As other pattern using the built-in formula, how about the following modified formulas?
=VALUE(TEXTJOIN("",TRUE,ARRAYFORMULA(IFERROR(VALUE(REGEXREPLACE(IMPORTDATA("https://api.pro.coinbase.com/products/ETH-USD/stats"), "open|""|{|}|:","")),""))))
=VALUE(TEXTJOIN("",TRUE,ARRAYFORMULA(IFERROR(VALUE(REGEXREPLACE(IMPORTDATA("https://api.pro.coinbase.com/products/ETH-USD/stats"), "volume_30day|""|{|}|:","")),""))))
In these formulas, the values can be retrieved by replacing KEY of KEY|""|{|}|: of the regex.
Other pattern 2:
The returned value from https://api.pro.coinbase.com/products/ETH-USD/stats is the JSON value. So in this case, when the custom function created by Google Apps Script can be also used.
The Google Apps Script is as follows.
const SAMPLE = (url, key) => JSON.parse(UrlFetchApp.fetch(url).getContentText())[key] || "no value";
When you use this script, please copy and paste the above script to the script editor of Spreadsheet and save it. And please put the custom function like =SAMPLE("https://api.pro.coinbase.com/products/ETH-USD/stats","open") and =SAMPLE("https://api.gdax.com/products/ETH-USD/ticker","price") to a cell. By this, the value can be retrieved.

Convert text to number in Google Sheets

I'm reading currency values from a website and I'd like to do some calculations with these numbers. They come in this format:
$7,821.24
Here's an example file:
https://docs.google.com/spreadsheets/d/1vHEH_m16KXcDh7hY_BVG9lur1huFjWOnx5bWtgrdGdA/edit?usp=sharing
Now for some reason neither VALUE() and TO_PURE_NUMBER work for me (Can't parse to numberic value, telling me it's a text value).
My guess is that the comma and the $-sign confuse the formula, is there anything I can do to format this correctly? The dollar sign always appears in the values but the comma only appears separating thousands of values.
I just started using Sheets for this so I absolutely have no clue. Would really appreciate if someone could help me out.
Thanks for your time!
Issue:
It's a locale problem. The value coming from IMPORTXML is formatted as in United States locale, so your spreadsheet (which uses a different format) cannot convert it.
Solution #1. Changing locale:
If the spreadsheet locale is changed to United States or others with the same format (via selecting File > Spreadsheet settings and setting the mentioned locale), the retrieved value will be a number, and you can work with it without using any other formula.
Solution #2. Formula:
If changing the locale is not an option, one possible way to convert the value to a valid number in your locale is the following formula:
=SUBSTITUTE(SUBSTITUTE(RIGHT(A2;LEN(A2)-1);",";"");".";",")
Changing locale didn't work in my case. But I was able to split the number which google sheet isn't detecting as a real number. So split it with "," and "." and any currency sign you may have, and then combine individual values for desired output

Replace 0's with FALSE and 1's with TRUE

I'm using a COUNTIF formula to find matches between two ranges. Of course, COUNTIF returns a numerical value, but I need TRUE or FALSE values. So I added NOT() to the formula, which gave me TRUE/FALSE, but in my case, the results were backward, so I added an additional NOT() to reverse the results and this works fine for my purposes.
My question is: is there a better way to do this? Obviously, this isn't a lot of characters to type (I've put more effort into typing this question...), but if there is a simpler, cleaner solution, I'd like to know.
Here is my full formula:
=NOT(NOT(COUNTIF(projectSelections!B2:B&projectSelections!C2:C,itemsAssociations!A3:A&itemsAssociations!B3:B)))
=ARRAYFORMULA(A1:A10=B1:B10)
=ARRAYFORMULA(REGEXMATCH(A1:A10, "^"&B1:B10&"$"))
=ARRAYFORMULA(IF(A1:A10=B1:B10, TRUE))
=ARRAYFORMULA(NE(A1:A10, B1:B10))
=ARRAYFORMULA(REGEXMATCH(""&A1:A10, "^"&B1:B10&"$"))
I don't know specifically about google sheets, but in general a double negation is not an unusual technique to convert a numeric value to a boolean.
Alternatively, there is also the possibility to check if the value is not equal to zero, which in the case of google sheets can apparently be done with the NE() function: NE(COUNTIF(...) ,0). As explained in the documentation, NE(a,b) is equivalent to a <> b.
You're overthinking. To get TRUE and FALSE just use
=COUNTIF(...)=0
Nothing wrong with what you did. Another option is to use Perl or Python to clean up the data file. You could export in CSV format or clean up before going into google docs.

Google spreadsheets - how to handle duration: store and use in calculations?

I've got a lot of "duration" values - basically a race duration - in a format m:ss.millis [4:03.810 for example].
Currently GS handles it as text, but I would like to use those values for comparison and create some statistics.
Is this possible? I have read this: How to format a duration as HH:mm in the new Google sheets but even though I have created a custom formats like:
or
but neither with one nor with another I cannot use those values for calculations. GS always complains about the values beeing stored as text.
I guess I'm just doing something wrong, but I definitely need to be able to provide values in this format and be able to use them in calculations.
How can I do that?
I regret that Duration seems to be a useless abomination and Sheets appears to offer no relatively easy way to convert text representation to values. Pending a better answer I suggest you convert all your durations as below:
=(left(A1,find(":",A1)-1)+right(A1,6)/60)/1440
format as Number:
mm:ss.000
and then apply your formulae.
(Change , to ; if required by your locale.)
A shorter formula might be used to cajole TIMEVALUE to work by including an hour value of 0:
=TIMEVALUE("00:"&A1)
A happy coincidence brought me back here because only very recently have I found that Google Sheets does offer a way to convert Text to Number (or I was having another aberration when I claimed otherwise). However, this still seems not to apply to Duration. Maybe there is yet hope though.
